Metagenomic insights into the role of gut microbes in the defensive ink “Tsunabi” of physeteroid whales
Hayate Takeuchi; Takashi Fritz Matsuishi; Takashi Hayakawa
Ecology and Evolution, 15, e71910, Wiley, 08 Aug. 2025, [Peer-reviewed]
English, Scientific journal, ABSTRACT

Whales of the superfamily Physeteroidea, which includes the genera Physeter and Kogia , exhibit a unique visual defense mechanism involving the release of dark reddish‐brown feces (locally called “tsunabi‐ink” in Japan) into the water to obscure themselves from predators and other threats. However, the mechanism underlying pigmentation remains unknown. Because physeteroids possess an enlarged distal colon that retains fecal material, a possible explanation is that symbiont microbial metabolism contributes to the feces pigmentation. To investigate this, we provided a shotgun metagenomic catalog of gut microbiomes from the intestinal tracts of eight cetacean species, including two physeteroids: a sperm whale ( Physeter macrocephalus ) and a pygmy sperm whale ( Kogia breviceps ). The colonic microbiome of physeteroids exhibited relatively high abundances of tryptophan metabolism genes, particularly indolepyruvate ferredoxin oxidoreductases ( iorA and iorB ), suggesting that physeteroids accumulate indole‐3‐pyruvate‐derived pigments in their colons. Furthermore, bacterial members of the phyla Bacillota and Bacteroidota were identified in the physeteroid colon as primary taxa conferring heavy‐metal resistance, which may be related to the primary predation of physeteroids on cephalopods, which bioaccumulate high levels of heavy metals. Prolonged fecal retention can expose gut microbes to chronic heavy‐metal stress and colonize them as heavy metal‐tolerant microbial communities, some of which may produce pigments to reduce their toxicity. Thus, we propose that tsunabi‐ink is a metabolic byproduct of shifts in the gut microbial community, influenced by the host's digestive physiology and foraging behavior through sustained ecological interactions with gut symbionts. Moreover, we believe that further empirical investigation would validate this hypothesis.

Scientific journal, Abstract. Sari WK, Rahmalinda WPF, Harlyan LI, Sambah AB, Matsuishi TF, Rust S. 2025. Fishing area mapping and gear competition in Paiton Waters, East Java, Indonesia. Biodiversitas 26: 636-650. Fisheries in the northern waters of Java Island, Indonesia, particularly in East Java, exhibit high complexity, requiring comprehensive management to effectively address multiple challenges. However, this complexity requires simplification of contributing variables to facilitate sustainable management. One potential solution is spatial clustering. This study aims to analyze species diversity, identify the distribution of fishing gear, cluster areas and fishing gear, and assess indications of competition between fishing gear operating at the Paiton Fish Landing Base (PPI). This study used the Hierarchical Cluster Analysis (HCA) method. The results showed that species diversity in Paiton waters was categorized as moderate (0.00-1.52), with species richness categorized as low (0.00-0.72). Spatial clustering identified two clusters of fishing areas and one cluster of different fishing gears. Fishing areas near the harbor and close to Madura Island are dominated by Indian scad Decapterus russelli, while the central part of the Madura Strait is dominated by Bullet tuna Auxis rochei. Gear groupings showed competition between gillnets and driftnets, both of which target Savalai hairtail Lepturacanthus savala. This research contributes to fisheries management by providing insights into the spatial distribution and competition of fishing activities, supporting better resource allocation and sustainable practices in the region.

Status of Southeast Asian fisheries: distinctive characteristics and pathways to sustainable fisheries

Fisheries Sceince, 91, 2, 205, 216, 05 Feb. 2025, [Peer-reviewed], [Lead author, Last author, Corresponding author], [International Magazine]
English, Scientific journal, Southeast Asia is a vast tropical region comprised of 11 countries and has experienced uniquely prominent development, particularly in capture fisheries. The large exclusive economic zones and continental shelf areas heavily support the region’s fisheries, with capture fisheries production having steadily increased over the past 30 years, outperforming other regions. The percentage of fishers as a share of the total population in this region is 3.4 times that of the world average. The region’s per capita supply of aquatic foods is 1.9 times higher than the world average. Despite warnings of overfishing for decades, the region has a 3.6 times higher ratio of underfished marine stocks as compared with the global estimate, primarily owing to the prevalence of artisanal or small-scale fisheries and non-selective fisheries, which are supported by high biodiversity. However, the growth of the per capita supply of aquatic foods has plateaued in recent years. As Southeast Asia’s population is expected to stabilize in about the year 2055 at 113% of its current size, the demand for aquatic food products will likely level off, enabling a transition toward sustainable fisheries.

AACL Bioflux, 16, 6, 3227, 3239, 30 Dec. 2023, [Peer-reviewed], [Last author, Corresponding author]
English, Scientific journal, Quantifying behaviour among captive odontocetes is important for understanding the social structure and managing the captive conditions. Based on frequent interactions, trainers of captive cetaceans establish perceptions of relationships between animals. Distances between individual cetaceans during synchronous breathing can be used to express social relationships among odontocetes. If the perceptions of trainers can be visualised, these diagrams represent graphically a useful tool to improve animal care. The study aimed to both quantify social relationships among captive odontocetes, and to visualise trainer perceptions, using the distance between individuals during synchronous breathing as a metric of odontocetes social cohesion. Data were collected from three pools at three facilities housing common bottlenose dolphins or harbour porpoises. Individuals distance for dyads (a pair of cetaceans in an interactional situation) were calculated using a combination of video recordings, visual observations, and body measurements. Proximity relationships between individuals in each pool were visualised using multidimensional scaling analysis (MDS). Mathematically predicted relationships among captive odontocetes were consistent with trainer perceptions of social relationships. We demonstrated that MDS can be used to visualise social relationships among captive odontocetes, and that these visualisations can be used to assist trainers and animal management to improve captivity conditions. Key Words: dolphin proximity, multidimensional scaling analysis, synchronous breathing.

English, Scientific journal, Rapid and accurate data gathering on fish catches and the geographical distribution of fishing activitiesis essential in fish stock assessments and fisheries management. Surveillance systems like the VesselMonitoring System (VMS) have become popular globally, providing accurate data on fishing activitiesand fish abundance in near real-time. Our study demonstrates a procedure to find the best methodin machine learning algorithms for detecting fishing operations from surveillance data. VMS dataof 3,237 trips conducted by 91 purse seiners targeting short mackerel (Rastrelliger brachysoma) inThai waters of the Andaman Sea during 2020 were used for the study. Twenty-five spatiotemporal,environmental, and fisheries-related parameters were investigated as predictors to detect and map thefishing activity. Eight algorithms were used to compare the model performance using cross-validation.The total catch per trip was reallocated to the predicted fishing locations of the trip from the bestalgorithms to depict the fishing ground. The results show that operation time and vessel speed areessential elements for determining the fishing operation of purse seiners. The most-relevant predictorsare the calculated speed, operation time, and instantaneous speed. The Random Forest (RF) algorithmperformed the best, with 86% accuracy, and therefore was used as the final model to detect thefishing operations. However, all reallocation approaches performed similarly well in depicting fishdistribution. The allocation of catch data equally to the fishing position is recommended since it is themost straightforward technique. In contrast, reallocation catch using the RF algorithm prediction ratiofor visualising the CPUE distribution achieved the best performance (with a slope of 1) compared withthe training data. This study provides the first decent procedures for using surveillance informationto detect and identify the prospective fishing operation of purse seiners—an approach that allowsfor a better understanding of short mackerel distribution. The proposed procedures should help withtime–area-based management of intensively exploited migratory fish species, which requires rapid andaccurate information.

English, Scientific journal, Besides a vital sector of the economy, agriculture is a primary source of greenhouse gas (GHG) emissions. The present paper investigates the impact of carbon tax policy on Vietnamese agriculture by focusing on multi-product systems such as rice, livestock, and aquaculture, traditionally called the Vuon (Garden)–Ao (Pond)–Chuong (livestock pen) system (VAC). In it, farmers use garden, pond, and pen by-products as fertilizer and feed. We use shadow prices and Morishima substitution elasticities as greenhouse gas emissions indicators, estimated with directional output distance function. Farmers in the Mekong Delta region are found to be technologically less efficient than in other regions of Vietnam, though the shadow prices of GHG emissions are lower there too. This indicates that farmers in the Mekong Delta, generally concentrating either on livestock or aquaculture, have greater potential for reducing GHG emissions by way of improvements in technical efficiency than do those in other regions. However, Morishima elasticity estimates show that policy impacts diminish more quickly in the Mekong than elswhere. We suggest the Vietnamese government encourage Mekong Delta farmers to employ technologically more efficient methods or shift to more balanced farming to reduce the shadow price of GHG emissions, encouraging more efficient emissions reduction.

English, Scientific journal, The brownbanded bamboo shark (Chiloscyllium punctatum) is a benthic shark species distributed in Southeast Asia. The species has been listed as “Near Threatened” by the IUCN, but only based on indirect information. In this study, yield per recruit (YPR) and spawning per recruit (SPR) analyses were conducted to determine the current stock status. Data were obtained from three major landing sites of this species: Sihanoukville, Cambodia (Sv); Songkhla, Thailand (Sk); and Kota Kinabalu, Malaysia (KK). The von Bertalanffy growth curve parameters L∞ and K were estimated as 81.62 cm and 0.37 year-1 for Sv, 88.09 cm and 0.51 year-1 for Sk, and 86.48 cm and 0.40 year-1 for KK. The YPR and SPR analyses showed that the Fcurr, F0.1, and F30% were 0.29, 0.26, and 0.21 year-1 for Sv; 0.39, 0.23, and 0.23 year-1 for Sk; and 0.06, 0.24, and 0.24 year-1 for KK. The results indicate that the fishery for brownbanded bamboo sharks in KK is efficient and sustainable, but in Sv and Sk, harvest is nearing inefficiency, and fishing mortality cannot sustainably be increased from the current level. Some fisheries management measures are recommended for the sustainability of these stocks.

English, Scientific journal, Traceability is considered the most important requirement for shrimp products exported to global markets. However, implementing traceability in shrimp-exporting countries is challenging because of limited production at the local supply chain and lack of financial welfare awareness. This study aims to investigate the expected farm-gate price for traceability implementation using a double-bound dichotomous choice experiment. The censored regression model is used to estimate the factors influencing the anticipated farm-gate price of shrimp farmers. The survey was conducted in Ca Mau Province, Vietnam, by interviewing 71 Penaeus monodon Fabricius, 1798, and 43 Penaeus vannamei Boone, 1931, farmers. To implement traceability, P. monodon farmers estimated the farm-gate price at 10.17 USD.kg-1 , while P. vannamei farmers expected 6.18 USD.kg-1 . Application of international quality assurance certifications, willingness to implement traceability, land used, culture methods, shrimp species, current farm-gate price, and variable costs affected the expected farm-gate price. The attractive anticipated farm-gate price compensated for the negative influence of applying international quality assurance certifications, indicating that the farmers were willing to implement traceability. This suggests that the application of certifications increased the ability to implement traceability in the shrimp supply chain. The attractive farm-gate price for certified shrimp products would enhance their willingness to implement the traceability of shrimp products.

English, Scientific journal, AbstractGrowth and maturity parameters of harbour porpoises (Phocoena phocoena) around Japanese waters were summarized using samples and information from 214 individuals stranded and bycaught along the coast of Hokkaido from 2009 to 2019. We estimated ages from dental growth layer groups (GLGs), made more accurate by independently determining the mean date when layers are established. Gompertz growth curves were fitted, predicting asymptotic lengths of 136.9 cm for males and 158.5 cm for females. Sexual dimorphism was present from 3 years of age, with females larger than males as reported in other subpopulations. Length at sexual maturity (LSM) and age at sexual maturity (ASM) were estimated as 143.1 cm and 7.7 years, respectively, for males, and 154.4 cm and 7.3 years, respectively, for females. In comparison with other studies that examined stranded and bycaught harbour porpoises in other locations, foetuses and neonates comprised a very small proportion of samples. Differences from other populations in the age distributions of pregnant females also indicated that the coastal area of Hokkaido is not used as an area for parturition. This study uses data from the past 10 years to provide basic information on growth and reproduction of animals in and around Hokkaido, which is part of the North Pacific subpopulation of harbour porpoises., 29849513;29849514

Feasibility of a single-species quota system for management of the Malaysian multispecies purse-seine fishery
Ledhyane Ika Harlyan; Matsuishi Takashi Fritz; Mohammad Faisal; Md Saleh
Fisheries Management and Ecology, 28, 2, 126, 137, 05 Mar. 2021, [Peer-reviewed], ［Internationally co-authored］, [International Magazine]
English, Scientific journal, Malaysian fisheries employ multiple measures to improve management; however, not all are well-suited to the multispecies fisheries. As part of a pilot project, an individual quota system was recently introduced for the purse-seine fishery off the East Coast of Peninsular Malaysia (ECPM), but no assessment of this particular measure nor the feasibly of its implementation has been confirmed. Therefore, this study analysed patterns of purse-seine fishing spatially and temporally, by collecting catch composition data per landing and its fishing ground within three period fishery surveys during August 2017 – September 2018 at six different landing. Similarity and cluster analysis were taken by examining species composition and diversity, to determine the feasibility of implementing a single-species quota system in this multispecies fishery. Some overlapped of indices results and minor difference in catch composition were found due to changes in spatial and temporal fishing activities. However, no specific spatial or temporal patterns were discernible as structuring the fishing grounds that were used by purse-seiners. The absence of patterns, using the available data, might be attributable to huge species aggregations and widely distributed and homogenously-mixed fish stocks. Thus, it is likely impractical to manage species individually in such a multispecies fishery.

Determinants of echolocation click frequency characteristics in small toothed whales: recent advances from anatomical information
Kuroda Mika; Miki Nobuhiro; Matsuishi Takashi Fritz
Mammal Reviews, 50, 4, 413, 425, 30 Sep. 2020, [Peer-reviewed], [Last author, Corresponding author], [International Magazine]
English, Scientific journal, The pulse‐like clicking sounds made by odontocetes for echolocation (biosonar) can be roughly classified by their frequency characteristics into narrow‐band high‐frequency (NBHF) clicks with a sharp peak at around 130 kHz and wide‐band (WB) clicks with a moderate peak at 30–100 kHz. Structural differences in the sound‐producing organs between NBHF species and WB species have not been comprehensively discussed, nor has the formation of NBHF and WB clicks.
A review of the sound‐producing organs, including the latest findings, could lead to a new hypothesis about the sound production mechanisms. In the current review, data on echolocation click characteristics and on the anatomical structure of the sound‐producing organs were compared in 33 species (14 NBHF species and 19 WB species).
We review interspecific information on the characteristics of click frequencies and data from computed tomography scans and morphology of the sound‐producing organs, accumulated in conventional studies. The morphology of several characteristic structures, such as the melon, the dense connective tissue over the melon (the ‘porpoise capsule’), and the vestibular sacs, was compared interspecifically.
Interspecific comparisons suggest that the presence or absence of the porpoise capsule is unlikely to affect echolocation frequency. Folded structures in the vestibular sacs, features that have been overlooked until now, are present in most species with NBHF sound production and not in WB species; the vestibular sacs are therefore likely to be important in determining echolocation click frequency characteristics. The acoustical properties of the shape of the melon and vestibular sacs are important topics for future investigations about the relationship between anatomical structure and sound‐producing mechanisms for echolocation clicks., 29849513

English, Scientific journal, The harbor porpoise is a marine mammal rarely seen in aquariums. The ecology of this species is not well known, and captive breeding is difficult without essential information such as milk composition, amount consumed and frequency nursed per day, and lactation period. At the Otaru Aquarium in Japan, several deliveries of harbor porpoise offspring have occurred, but the calves have not survived. In the present study, we analyzed the colostrum of a harbor porpoise and attempted to hand-rear a calf using artificial milk after the mother denied nursing. The crude fat and crude protein contents of the colostrum were relatively high compared to values for other odontocetes. The present information will be helpful for future efforts to hand-rear harbor porpoises.

English, Scientific journal,

A serologic investigation of Brucella infection was performed in 7 species of cetaceans inhabiting along the coast of Japan. A total of 32 serum samples were examined by enzyme-linked immunosorbent assay (ELISA) using Brucella abortus and B. canis antigens. One serum sample from five melon-headed whales (Peponocephala electra) was positive for B. abortus. No serum sample showed positive for B. canis. The ELISA-positive melon-headed whale serum demonstrated a strong band appearance only against B. abortus antigens in Western blot analysis. Many detected bands were discrete, while some of them had a smeared appearance. The present results indicate that Brucella infection occurred in melon-headed whale population and the bacterial antigenicity is more similar to that of B. abortus than B. canis.

Journal of Veterinary Medical Science, 81, 6, 897, 902, Japanese Society of Veterinary Science, 17 Apr. 2019, [Peer-reviewed], [International Magazine]
English, Scientific journal, Systemic amyloidosis is rarely reported among cetaceans, and a surveillance dedicated for its occurrence across a certain geographic location has not been reported. Between 2013 and 2018, comprehensive gross and histopathologic examinations were conducted on 54 animals comprising 11 species of stranded and bycaught cetaceans in Hokkaido, Japan. Systemic amyloidosis was diagnosed in 2 out of 3 Stejneger's beaked whales (Mesoplodon stejnegeri), through Congo red staining and immunohistochemistry for amyloid A. The kidney and gastrointestinal tract had the largest amounts of amyloid deposits, representing a previously undescribed organ distribution in the species. The current study demonstrates the possibility of Stejneger's beaked whales being prone to the development of systemic amyloidosis, and highlights the need for further investigations.

English, Scientific journal, This study aims to conduct the consumer’s willingness to pay (WTP) for traceable pork products by using the auction experiments methods, estimate the factors affecting to the WTP and identify the demand for specific information in traceability systems from information of consumers in Vietnam. The results indicated that, the WTP for traceable pork products of consumers is higher than 24%, comparing to the non-traceable pork products. The frequency of pork consumption, gender, age, education, health self-report and consumer’s attitude from risk of unsafe pork products were the influencing factors to the consumer’s WTP for traceable pork. The necessary information of traceability, suggested by consumers, included: information of additives included in the purchased pork, place of origin, expiration date and quality certificate.

English, Scientific journal, Shrimp products play a vital role in the international trade of fisheries products. The main suppliers for shrimp products are developing nations such as Vietnam, Thailand, Bangladesh and other countries in Southeast Asia. Among them, Vietnam is one of the largest exporters of shrimp products, and developed countries, especially the United States, Europe and Japan, are key importers of shrimp in the global market. An increase in the demand for shrimp products has led to the development of traceability regulations in developed countries. In this study, Pressure–State–Response (PSR) concepts are applied to evaluate the implementation responses of traceability regulations by exporting countries to meet the mandatory requirements of global markets. The evaluation was based on the prepared questions that were developed to allow comparison of specified indicators in the traceability regulations of importing countries and those of Vietnam. The examination showed that importing countries have introduced stringent traceability regulations via legislation and quality assurance practices. Regarding measures taken by exporting countries, Vietnam has introduced traceability regulations for both shrimp and other seafood products. Thus, Vietnamese regulations were found to satisfy the regulations of importing countries. However, the implementation of these regulations has faced a number of challenges, largely because of complicated of distribution channels, small-scale production, price discrimination and a lack capital to apply for international certificates.

Marine Pollution Bulletin, 136, 230, 242, Nov. 2018, [Peer-reviewed], [International Magazine]
English, Scientific journal, Species-dependent profiles and regional trends in naturally produced halogenated bipyrroles (Br4Cl2-DBP and Cl7-MBP), methoxylated tetrabromodiphenyl ethers (MeO-BDEs), and anthropogenic erfluoroalkyl carboxylic acids (PFCAs) were investigated in the livers of 14 cetaceans from the Sea of Japan and the North Pacific Ocean. Levels of Br4Cl2-DBP were high in cetaceans from the North Pacific (up to 4,900 ng/g-wet), whereas Cl7-MBP was abundant in cetaceans from the Sea of Japan (up to 3,900 ng/g-wet), indicating different sources for the bipyrroles. PFCAs were dominated by perfluoroundecanoic acid and perfluorotridecanoic acid (up to 540 ng/g-wet) in cetaceans from the Sea of Japan, reflecting a potential source of long-chain PFCAs in this region. Concentrations of 6- MeO-BDE47 were widely distributed (up to 190 ng/g-wet) in cetaceans in both oceans. These natural products could serve as a tracer or marker to determine temporal or regional trends in anthropogenic PFCAs and/or newer contaminants in cetaceans.

Japanese, Scientific journal, The morphological characteristic of the tongue of a Neonate Minke whale (Balaenoptera acutorostrata) was observed on gross and with scanning electron microscopy. The tongue was oval shaped, and had the marginal papillae of various forms on the both sides of the anterior part. Three types of papillae (dome-, short cylindrical- and club-shape) were found on the surface of the tongue. Dome-shape papillae were distributed on the anterior surface of the tongue, and the short cylindrical- and club-shape papillae were distributed on the several grooves of the posterior surface of tongue. The connective tissue cores of these papillae were dendritic shape, fist-like, and cauliflower-like shape, respectively.

English, Scientific journal, Dall's porpoise (Phocoenoides dalli) is one of most common North Pacific porpoise species, for which information on sound-emitting processes is limited. To evaluate the mechanism of click emission in the head of this porpoise, the distribution of acoustic impedance in head tissues was calculated using density and Young's modulus'which is a measure of linear resistance to linear compression. Two Dall's porpoise heads were examined: one for macroscopic dissection, and one for investigating the distribution of acoustic impedance calculated from CT-measured density, and Young's modulus measured by creep meter. Acoustic impedance increased from the dorsal bursae to the melon's emitting surface, with impedance matching observed at the boundary between the emitting surface and seawater, and was more similar in distribution to Young's modulus than it was to density. The distribution of acoustic impedance differed from that of harbor porpoise (Phocoena phocoena), despite similarities in the sound producing organs in the heads of Dall's and harbor porpoises. A comparison of the physical properties of Dall's and harbor porpoise head tissues suggests that hypertrophic vestibular sacs and an oval emitting surface are common characteristics in Phocoenidae.

English, Scientific journal, Beaked whales are among the least known group of cetaceans, and information regarding their pathology and parasitology is especially scarce. We describe a case of significant parasitism by a trematode found in the liver of an adult male Hubbs' beaked whale Mesoplodon carlhubbsi that stranded in Hokkaido, Japan. Post-mortem examinations revealed a localised area of discolouration restricted to the hilar region of the left hepatic lobe, where spindle-shaped trematodes occupied the dilated and hypertrophic bile ducts. Histologically, the intrahepatic bile ducts were characterised by adenomatous hyperplasia with goblet cell metaplasia of the biliary epithelium. Findings in the adjacent hepatic parenchyma included pseudocarcinomatous ductular reactions obliterating hepatocytes, a histomorphology not previously reported in marine mammals. Morphological identification of the trematode corresponded to Oschmarinella macrorchis, which has only been reported once in a Stejneger's beaked whale, M. stejnegeri. PCR amplification and sequencing analyses of the parasite's mtDNA ND3, 18S and 28S rRNA regions generated novel gene sequences. Environmental contaminant levels were measured to explore its potential relationship with the parasitism but there was no conclusive association. A high level of polychlorinated biphenyl (30000 ng g-1 lipid weight) was detected in the blubber of this individual, when compared to those of 3 other male Hubbs' beaked whales stranded in Japan. Stomach contents were also analysed, indicating the presence of various squid species and unidentified fish. Our results contribute to the knowledge of a little-known beaked whale and provide evidence for the first time of the pathobiological response caused by O. macrorchis.

Evaluation of the Sustainability on the Walleye Pollock Fishery off Pacific Coast of Hokkaido by using the MSC Fishery Standard
Fukutake C; Matsuishi T; Nagano I
Bulletin of Fisheries Sciences, Hokkaido University, 64, 3, 83, 87, 北海道大学大学院水産科学研究院, Dec. 2014
Japanese, Research institution, To evaluate and improve the sustainability of Walleye Pollock fisheries for the Pacific stock according to the global standard, the fisheries is evaluated by MSC Fishery Standard which is a globally recognized requirements for an eco-label certification of sustainable fishery published by the Marine Stewardship Counsil. MSC Certification Requirements were used which describes the scoring of 31 performance indicators (PI) grouped to three principles, (1) stock assessment, (2) ecological consideration, and (3) fishery management. For the certification, all score should be over 60, and the average score for each principles should be over 80. The evaluation was carefully conducted by two researchers independently based on the disclosed information. As a result, the total average score was 78.3, and the average score for each principle was (1) 92.5, (2) 69.0, (3) 84.4. The scores of the 4 PIs in principle 2 were under 60. Thus, the fisheries of the Walleye Pollock Pacific stock does not meet the requirements as sustainable fishery as the current condition according to the MSC standards. The main cause for the low score is the lack of the monitoring of the otter trawl fishery on the damage to the sea bed, and on the by-catch. An observers program would improve the sustainability of the fisheries.

Japanese, Scientific journal, A Spatial distribution of cetacean has been thought to be closely related to marine environment, such as sea surface temperature, chlorophyll-a concentration, sea floor gradient, and water depth which may affect an abundance of prey and in turn may affect spatial distribution of cetacean. In this study, from the data of sighting survey in Tsugaru Strait conducted by Hokkaido University cetacean research group, encounter rate and degree of aggregation of Pacific white-sided dolphin (PWS) were examined for every division. In addition to this, a relationship of a spatial distribution of PWS to the marine environment ware also examined by using generalized linear mixed model (GLMM). From these analysis, it was shown that PWS is aggregated on one or two divisions inside a bay area. Moreover, the division where PWS aggregated had feature low sea surface temperature and low chlorophyll-a concentration. Prevented studies show that aggregation of cetacean related with high chlorophyll-a concentration, however, the result of this study indicated the opposite tendency to these studies. Additionally the aggregation of PWS was seen regardless of the feature low sea surface temperature and low chlorophyll-a concentration. Thus it was showed that in spite of the environment the spatial distribution of PWS is determined in Tsugaru Strait

Japanese, Scientific journal, The cetacean sighting records from 375 sighting survey in the Tsugaru Strait for ten years were compiled and the seasonal variability and yearly trend of cetacean encounter was examined. A total of 1876 school 19065 individuals were observed, and at least 7 species are identified such as Pacific white-sided dolphin, Dall’s porpoise, Habour porpoise, Minke whale, Bottle nosed dolphin, Common dolphin, and Killer whale. Except for Killer whale, the encounter of all of the cetacean were peaked during April to June. The encounter is rare during August and October, and no encounter has been recorded for this season for 10 years except for Pacific white-sided dolphin and Habour porpoise. The encounter rate of Harbour porpoise has been significantly increased. No encounter of Common dolphin and Bottle-nosed dolphin has been recorded after 2004, and the encounter to Killer whales had been occurred after 2009.

Fish diversity and abundance of Lake Tanganyika: comparison between protected area (Mahale Mountains National Park) and unprotected areas
Sweke,EA; Assam,JM; Matsuishi,T; Ch; e,A
International Journal of Biodiversity, 269141, 269141, 1, 10, Feb. 2013, [Peer-reviewed]
English, Scientific journal, High biodiversity is the most remarkable characteristic of Lake Tanganyika including vertebrates, invertebrates, and plants. A few protected areas have been created along the lake to protect its biodiversity. However, limited studies have been carried out to ascertain their effectiveness. The current study aimed at assessing and comparing fish diversity and abundance of Lake Tanganyika in a protected area (Mahale Mountains National Park (MMNP)) and unprotected areas surrounding it. The data were collected in the near shore zone at 5?m and 10?m depths using stationary visual census (SVC) technique. The protected area recorded higher fish richness and abundance than unprotected areas. It was concluded that the protected area is effective in conserving the fish diversity and abundance of the lake. However, more studies should be carried out regularly to explore the efficacy of the protected area in conservation of aquatic biodiversity and abundance.

Japan Cetology, 22, 9, 13, 日本セトロジー研究会, Aug. 2012, [Peer-reviewed]
Japanese, Scientific journal, Dalls’s porpoise, Phocoenoides dalli stranded in Hokkaido were studied for their stomach contents. Seventeen individuals were reported from May to July in 2008. This is biggest number to have been reported within such a short period of time in the history of stranding recorded in the紅 白 Nine and ten individuals were reported in 1997 and 2005 respectively but neither clear details nor stomach contents were recorded. The paper reported the stomach contents of Dall’s porpoise and clarified the species of their prey. The stomachs were taken from thirteen individuals. Six individuals had empty stomachs. These individuals were small in size compared to individuals with partly filled or filled stomachs. To investigate the quantitative composition of the stomach contents, frequency of occurrences and composition of the prey species were determined. The stomach contents revealed that the porpoises fed mainly on Gonatidae species. This was different from the previous studies in which walleye pollock Theragra chalcogramma was the main prey. In this study, stomach contents showed that walleye pollock was not a prey in any Dall’s porpoise. This suggested that the main prey species have changed probably due to decrease in population of walleye pollock in recent years.

Japanese, Scientific journal, Pacific white-sided dolphin (PWS) Lagenorhynchus obliquidens is the most common cetacean species found in the Tsugaru Strait, Japan. It is suggested that PWS use this strait as a feeding ground and Japanese anchovy is one of the major prey species. PWS also feed Walleye Pollock, Squids and Salmonidae. The population of PWS migrated in the Tsugaru Strait fluctuate every year. In this study, the PWS population migrated in the Tsugaru Strait from 2004 to 2009 were estimated. Moreover, the relationship between the population of PWS and an abundance of Japanese anchovies was examined. The estimated population fluctuated between 2,000 and 8,000 every year. A significant correlation was found between the PWS population and the abundance of Japanese anchovy Pacific stock (r^2= 0.75, P=0.0249). Regression analysis between the PWS population and catches of other prey species, such as Walleye Pollock, Cherry salmon, Japanese common squid and Japanese anchovies in the Tsugaru Strait, and the surface water temperature were also conducted. As a result, no significant correlations were found. The fluctuation of PWS population migrated in the Tsugaru Strait was affected by the population of Japanese anchovies in the Pacific Ocean. It suggested that the majority of PWS in the Tsugaru Strait are migrated from Pacific Ocean.

Interdisciplinary Studies on Environmental Chemistry-Marine Environmental Modeling & Analysis, 221, 228, 2011, [Peer-reviewed]
English, International conference proceedings, In the present study, stranded or by-caught Harbour porpoises (Phocoena phocoena) and Dall 's porpoises (Phocoenoides dalli) were collected from Hokkaido, Japan, and brominated flame retardants (PBDEs and HBCDs) and Polychlorinated bipl1enyls (PCBs) concentrations in their blubber were measured. All the target compounds were detected in all the specimens. Levels of PCBs were significantly higher thar1 those of PBDEs and HBCDs. PCBs, PBDEs and HBCDs levels in harbour porpoises of the present study were lower than those in Dall's porpoises (p=0.03). This result might reflect the difference in habitat and feeding behavior between these species. Additionally, HBCDs levels in harbor porpoises and Dall's porpoises analyzed in this study were higher than finless porpoises from Seto Inland Sea, suggesting contamination by HBCDs is more serious in Hokkaido. To evaluate the temporal trends, blubber samples of adult male harbour porpoises and Dall's porpoises collected in 1985- 2009 and 1980- 2008 were analyzed. Concentrations of PCBs in both species did not sl1ow any trend during 1980- 2009. In contrast, remarkable increasing trend of HBCDs in Harbour porpoise was observed. PBDEs and HBCDs concentrations ir1 Dall's porpoises also increased during the survey period. These results suggest growing consumption of these chemicals in Japan and surrounding countries in recent years.Proceedings of interdisciplinary studies on environmental chemistry Vol. 5 Modeling and analysis of marine envrionmental problems, Koji Omori, Xinyu Guo, Naoki Yoshie, Naoki Fujii, Itsuki C.

English, International conference proceedings, The present study investigated the accumulation features and metabolic capacities of PCBs and OH-PCBs in the blood of harbor porpoises, Dall's porpoises and finless porpoises stranded or bycaught along the Japanese coastal waters. OH-PCBs concentrations were the highest in Dall's porpoise (61 pg/g wet wt), followed by finless porpoise (23 pg/g wet wt) and harbor porpoise (14 pg/g wet wt), and the level in Dall's porpoise was significantly higher than that of harbor porpoise (p < 0.05). There was a positive correlation between PCBs and OH-PCBs concentrations (r = 0.62, p < 0.001), suggesting possible induction of CYP enzymes in a concentration dependent manner. Distinct OH-PCB congener patterns were observed among the three porpoise species. These species specific accumulation patterns are possibly due to the differences in their metabolic capacity for PCBs, such as the induction of CYP enzymes, substrate specificity in phase I and II enzymes and/or affinity of OH-PCB congeners to Transthyretin (TTR).

Japanese, Scientific journal, From the sighting survey in the TsugaruStrait, which is located betweenHokkaido and Honshu in northern Japan, it is known that Pacific white-sided dolphin (PWS) is the most common cetacean species in this strait, and is mostly observed from April to June. In this study, to show temporal changes of school size of PWS in the strait, the data were analyzed which is obtained from sighting surveys on a ferry between Hakodate,Hokkaido and Aomori, Honshu from May 2003 to September 2009 The school size of PWS in March to July was analyzed by using smooth spline. Its school size was large in April when PWS came to the strait, small in May to the beginning of June whenP WSf ed on prey in the strait,a nd large in mid-June again when PWS went out of the strait. These result supported the past study.

Japanese, Scientific journal, In spring, the Pacific white-sided dolphin (PWS) comes to the Tsugaru Strait and is observed mostly from April to June. In this study, we analyzed the data of sighting surveys conducted from ferry vessels between Hakodate and Aomori from May 2003 to August 2008, and examined the migration of PWS in the strait. The distribution of PWS varied during this period. In March, April and early May, PWS were observed in the northern part of the Tsugaru Strait. Between mid-May and mid-June, the distribution of PWS expanded to cover all the Tsugaru Strait. Between late June and July, PWS were observed in the southern part of the Tsugaru Strait. Subsequently, PWS were not observed. This migration pattern was found in all survey years.

Japan Cetology, 15, 13, 19, Oct. 2006, [Peer-reviewed]
English, Scientific journal, A histological examination was carried out on a young harbor porpoise, Phocoena phocoena (♀), 1.3m long, caught in a set net installed off Takashima, Otaru City, Hokkaido, facing the Sea of Japan. The formalin-preserved left lobe of the ovary was 13mm long and 0.2g in weight, the right lobe being 20mm and 0.2g, respectively. Both lobes were smooth, flat and disc-shaped, and revealed similar microscopic conditions which confirmed the young age of the animal. The cortical region comprised a number of primordial-and primary follicles, and few secondary follicles, whereas the medullary region, consisting of a large amount of interstitial tissue, included a few vesicular and many atretic follicles, in association with spiral arteries. However, no Graaffian follicles were encountered, and the uterine glands were simple and underdeveloped.

English, Scientific journal, Fisheries resources are resource is a great natural asset to this planet and ensuring the responsible use of these resources can enrich the lives of its people. However, global fishery resources are under high and mounting pressure which is severe, particularly in the developing countries. Until recently, traditional fisheries management failed to prevent over-exploitation and degradation and often ignored the socio economic aspects in the case of small-scale fisheries. Moreover, many developing countries face major constraints in capacity and the ability to promote implementation of long-term sustainable policies. International concern about people and their resources has significantly impacted thinking about how fisheries should be managed and the need for greater responsibility by fishers and managers is becoming more frequently heard. Bangladesh, a reverine developing country of South East Asia where more than 70% of the population lives in flood plain and coastal situations, fisheries resources suffer from severe over-exploitation so resource protection is important in sustaining the contribution of aquatic products to food security and livelihoods for the people. This situtation urgently requires effective management measures. This This can be best achieved by involving all user groups and the national fisheries agency, as the leader of the managers, for long term success oriented ultimately towards societal well-being, and based upon economic and resource sustainability. The purpose of this paper is to provide background information on the fisheries of Bangladesh and to justify the implementation of community-based fisheries management (CBFM) as vital if sustainable solutions are to be found.

English, Scientific journal, along the coast of Hokkaido, Japan was examined based on RPSI, imposex frequency, and sex ratio. The extent of imposex was compared between species in shallow waters and deep waters. In whelks in shallow waters, imposex was observed, with low RPSI values. However, for whelks in deep waters, there is no need to put imposex in question in all localities. Imposex was not found at all among whelks, or if any, only very few whelks with very slight imposex were observed. From this fact, it is considered that whelks in deep waters are less subjected to the influence of TBT, or that at present, the whelk populations have recovered from imposex, even though they had been affected by the use of TBT compounds.

English, Scientific journal, The ovaries (each 25mm in length) of a female harbor popoise, Phocoena phocoena, accidently caught in a set net on 26 April 2004, were examined histologically to assess their degree of maturity. The sectioned cortical region was occupied entirely with numerous primordial and primary follicles, whereas in the medullary region a small number of secondary follicles, thick-walled arteries and thin-walled veins were apparent. A few atretic follicles were also encountered. However, more developed follicles, such as Graafian follicles, were not detected. No secretory substance could be demonstrated in the mucous epithelia of the oviduct and underdeveloped uterine glands. The specimen appeared to be an infant owing to its very immature ovarian architecture.

Surfacing Interval of Minke Whale Balaenoptera bonaerensis in Antarctic
Saito T; Ikeda H; Matsuishi T
Bulletin of Fisheries Sciences, Hokkaido University, 55, 1, 7, 10, Hokkaido University, Aug. 2004
Japanese, Research institution, The surfacings of minke whales were collected through direct observation from JARPA (Japanese Whale Research Program under special permit in the Antarctic) and analyzed to see the distribution and average of the surfacing interval. The distribution of surfacing interval was found to be of single-peeked and long tailed. The average was 1’ 35’’ with all data. The averages for group size of 1, 2 and 3 were 2’ 11”, 1’ 54” and 55” respectively. The result of surfacing interval of this study was observed longer than that of the other studies in Antarctic. It is thought that this difference resulted from the difference of surfacing definition among studies.

Winter sightings of humpback and Bryde's whales in tropical waters of the western and central North Pacific
Ohizumi,H; Matsuishi,T; Kishino,H
Aquatic Mammals, 28, 1, 73, 77, Jan. 2002, [Peer-reviewed]
English, Scientific journal, Sighting surveys of cetaceans were conducted in tropical waters of the western and central North Pacific during January and February 1993. In total, 51 schools and 1915 individuals were sighted, including humpback whales, Bryde's whales, sperm whales, striped dolphins, and other unidentified cetaceans. Humpback whales were sighted around Hawaii and Iwo Island. Surveys around the Pagan and Agrihan Islands in the Northern Mariana Islands yielded no sightings. The probable southernmost area of the common wintering and breeding grounds of humpback whales in the Ogasawara-Mariana region is around the Kazna Islands, including Iwo Island. A solitary humpback whale was sighted some distance from Hawaii, which may have been a 'wanderer' that was flexible in its selection of wintering grounds. Bryde's whales were sighted in the central North Pacific at about 20 degree N. This area is just south of the summer distribution of Bryde's whales. The wintering area of Bryde's whales in the central North Pacific partially overlaps with the summering area. About 20 degree N may be the northernmost boundary of the pelagic wintering area that extends from the western North Pacific to the central Pacific.

Relationships between otolith weight and fish swimming speed
Mori,T; Noda,T; Matsuishi,T; Lee,TH
Journal of the Fisheries Society of Taiwan, 28, 3, 203, 207, 01 Sep. 2001, [Peer-reviewed]
English, Scientific journal, The otolith is an important part of the sensory organ of fish in detecting their direction and keeping balance through the movement of the otolith when swimming. The size of the otolith tends to vary according to the swimming speed of different fishes as the higher the speed, the smaller the otolith. Therefore, the deduction model was made to show the relationships between gravitational force being received by one cilium according to the otolith and fish swimming speed, and the aspect ratio was used as index to estimate fish swimming speed. Various otoliths were obtained from seventeen species of fish and otolith weight/body weight and aspect ratio were measured and regression analysis was performed to check whether or not the formula fit these data of otoliths and aspect ratio. The formula fitted the actual data well (R^2=0.735), and suggesting that fish have taken a strategy of adapting to their different swimming sty les by changing the otolith size more than by changing the cilium sensitivity.

Stock structure of walleye pollock, Theragra chalcogramma, around Hokkaido and Sakhalin in the term of mitochondrial DNA RFLP
Mizuno M; Kobayashi T; Matsuishi T; Maeda K; Saitoh K
Science Reports of Hokkaido Fisheries Experimental Station, 57, 1, 1, 8, 北海道立水産試験場, 31 Mar. 2000
English, Scientific journal, For the understanding about stock structure of walleye pollock, Theragra chalcogramma, around Hokkaido and Sakhalin, variation in mitochondrial DNA (mtDNA) was examined via restriction endonuclease digestions in 196 walleye pollock from 7 areas. Ten enzymes produced variant restriction patterns both within and among populations, and significant differences in their haplotype frequencies were detected between walleye pollock from off the east coast of Sakhalin and the others, therefore its genetic independence was estimated. But all of their genetic divergences in terms of nucleotide substitution were fairly small. From these evidences, we could draw tentative conclusions about stock structure of walleye pollock around Hokkaido and Sakhalin, that a genetically distinct population existed in the Okhotsk Sea, and that among stocks of around Hokkaido and Sakhalin either genetic differentiation was not so progressed or genetic exchange occurred.

Growth curve of abalone
Matsuishi T; Saito K; Kanno Y
Bulletin of the Faculty of Fisheries Hokkaido University, 46, 3, 53, 62, Hokkaido University, Dec. 1995
Japanese, Research institution, von Bertalanffy's growth curve has been widely used to express the growth of abalone, but this curve is known to fit poorly for the young growth stages. We used the von Bertalanffy, Logistic, Gompertz's, and Richards's growth curves to fit the length-at-age data of three populations of abalone collected in the southern part of Akita Prefecture, Japan. Generally, the AIC of the von Bertalanffy's growth curve was highest, and the logistic growth curve had a low AIC. Thus the logistic growth curve is thought to express abalone growth best. We also fitted this curve to length-at-age data by individuals, and examined the correlation among the parameters. Loo has a positive correlation with K and a negative correlation with c. This indicates that individuals that undergo slow growth during their young stages tend to become large.

An estimation method of population abundance using purse seine fishery catch-effort data
Matsuishi T
Bulletin of the Faculty of Fisheries Hokkaido University, 44, 3, 116, 126, 北海道大学, Aug. 1993
Japanese, Research institution, The catch per shot (CPUE) is often used as a population index, not only for demersal fish but also pelagic fish. However, this only represents the weight of the school in purse seine fishery, because one school is caught in one shot. Because there is no direct relationship between the weight of a school and its population abundance, CPUE cannot be used as an index of the population abundance in purse seine fishery. When searching time data for schools is available, the number of schools can be estimated from this data. From the estimate of school number and weight of school (CPUE), the population abundance can be estimated as the product of both estimates. A method to estimate the population abundance from these data was proposed, and was applied to the purse seine fishery data in the Southeastern Hokkaido region. From the results of such an estimation, a strong correlation was found between the weight of a school and the number of schools. The possibility of school selection in relation to the population density is suggested.

今年度はかいあし漁業の内容を広く一般に普及させるための情報発信を主に行った。国内学会の発表２件に加え、Fish of the Month (FoM) という、北海道大学水産学部の研究成果を紹介するHPにおいて、本科研費の研究分担者を主とする５名による、かいあし漁業に関する内容を紹介した。紹介内容と紹介者は以下の通りである：「海洋生態系におけるカイアシ類の重要性とかいあし漁業への夢（山口 篤）」、「カイアシ類の音響探知（向井 徹）」、「カイアシ類の音響散乱特性（福田美亮）」、「カイアシ類を対象とした商業漁業（藤森康澄）」、「カイアシ類-新たな水産脂質供給源として（別府史章）」。
カイアシ類を対象とした研究論文として、北太平洋亜寒帯域に優占する日周鉛直移動を行うカイアシ類Metridia pacificaの一次生産への摂餌インパクトを推定し、呼吸量による輸送量の推定を行った。これは、表層（0-50 m）と深海（50-200 m）の水温条件下において、同種の雌成体を飼育し、呼吸による酸素消費量を測定し、現場の表層における摂餌量の推定と、深海における呼吸による炭素輸送量を推定したものである。夜間の表層における個体数は１平方メートルあたり27～5422個体の間にあり、昼間の表層には本種は出現せず、これは日周鉛直移動の反映と考えられた。日周鉛直移動バイオマスは、１平方メートルあたり1-309 mg Cであった。1日の夜間表層と昼間深海での滞留時間を考慮すると、1日あたり１平方メートルあたりの摂餌量は0.04-11.04 mg Cと推定され、これは現場一次生産量の0-2.4％を占めていた。一方、昼間深海での1日あたり１平方メートルあたりの呼吸量は0.02-9.39 mg Cと計算された。これは有光層からの沈降粒子輸送量の0-10％に相当しており、物質循環における重要性が示された。

Harbour porpoise is strongly affected by human activities because its habitats is near shore. Wide range of researches are conducted in Europe and North America but little in Japan. Recently, stranding network and acoustic observation devices has developed in Japan, which enable to conduct new approach to the research of harbour porpoise. In the current study, specimens are collected from stranded and by caught harbour porpoise to analyse the diet and the conflict between fisheries. Also by using acoustic devices, observations are conducted around fishing gears to clarify the behaviour around the gears. From these result, conflicts between harbour porpoise and fisheries are described which will help to find a sound coexistence between cetacean and human.

We investigated organohalogen contaminants in blubber of cetaceans stranded at the Japanese coast to elucidate the contamination status and to estimate the toxicological risk of those contaminants. Concentrations of PCBs, DDTs, HCHs and HCB in adult male blubber showed significant decreasing trends during the research period (p < 0.05). Because the use of POPs was restricted worldwide, these chemicals showed decreasing trends. On the other hand, substantial increase of PBDEs and HBCDs were observed, suggesting growing consumption in Japan and other Asian countries during the study period. Since the contaminant levels exceeded the reference dose of some toxicological effects, adverse effects on cetaceans’ health were concerned.

小池 裕子; 松石 隆; 西田 伸
本研究では、鯨類の特に座礁集団および個体に着目し、座礁の原因究明の一つの手段として、ウィルス感染の有無とその動向のモニタリング、および検出されたウィルスの系統解析をおこない、宿主-ウィルスの共進化関係の有無と、免疫遺伝子MHCとの相互関係について探ることを目的としてきた。本年度も引き続き日本各地において座礁・混獲された鯨類より試料の収集をおこない、10鯨種・47個体の試料を得た。これは北海道ストランディングネットワーク・北海道大学・国立科学博物館・大村湾スナメリネットワーク(仮称)・宮崎くじら研究会との連携によるものであり、本プロジェクトもこれらネットワークの構築・運営の一部に携わっている。これまでに蓄積された試料について、DNA診断によるウィルス検出をおこなったところ、4鯨種・4個体よりヘルペスウィルスが検出された。本年度は特にこれらの系統解析と病理学的所見との関連性について解析を進めた。系統解析の結果、カズハゴンドウの鼻腔粘膜およびオキゴンドウの肺より検出されたウィルスは、それぞれ新たな系統のアルファヘルペスで、オウギハクジラおよびマッコウクジラのリンパ節からのものは、同じく新たな系統のガンマヘルペスと同定された。鯨類から検出されたアルファヘルペスウィルスは単一のクレードを形成し、種1分類群特異的な進化が示唆された。一方で、ガンマヘルペスウイルスの鯨類クレードは大きく2つに分かれており、これらウィルスの起源が複数あることを示した。またアルファヘルペスウィルスは主に呼吸器系統から、先行研究におけるガンマヘルペスウイルスは主に生殖器から、そして本研究によるガンマヘルペスウィルスはリンパ節から検出され、これらの系統のウィルスがそれぞれ異なる組織をターゲットとし、潜伏感染をおこなっていることが示唆された.なおこれらの結果は学術誌に投稿中である。

B & K社製水中マイク8103型および他の研究経費にて開発したマイクアンプ試作器を用いて,サンプリング1MHz,量子化ビット数16bitにてネズミイルカ鳴音を収録する手法を確立し,2005年3月2日に小樽水族館にてネズミイルカ鳴音の収音を行った。
ネズミイルカの鳴音の多様性について
上記の鳴音および,2004年4月に臼尻水産実験所屋外水槽,2004年8月20日〜9月3日に小樽水族館にて収録した鳴音について,LPC分析を用いてクリック音のピーク周波数抽出を行い,その時系列変化を解析した。
その結果,1クリックの間に鳴音の周波数に変化が見られた。コウモリと同様の周波数変調された音をエコロケーションに使用している可能性が示唆された。
ネズミイルカの鳴音のクリックインターバルと行動の関係
2005年4月に臼尻水産実験所屋外水槽にて,給餌時の鳴音を収録した。同時に行動をビデオカメラにて収録し,目標物へのアプローチ行動と鳴音についての関係を調べた。その結果,クリックインターバルは2msおよび5msにピークを持った。これはエコロケーションで4mおよび1.5mに認識の照準をおいていることに相当する。ビデオ映像の解析より餌が提示されているときは餌の4m手前にて遊泳周回行動が変化していた。このことより,クリックによる認識が行動に影響を与えていることが強く示唆された。

MATSUISHI Takashi; ITO Kiyohide; SASAKI Masato; IIDA Koji; SUZUKI Kentaro
The stranding records of Harbour porpoise Phocena phocoena collected by Institute of Cetacean Research was analyzed and the high proportion of the stranding was reported on April and May. The most frequently reported stranding place was Usujiri (36 individuals) and the next was Shiraoi (7 individuals). The number of bycatch individuals confirmed by our survey was 16. From the observation of ovary, they were immature. The passability experiment was conducted in the pool of Otaru Aquarium for an individual and found that the 50% passable aperture width was 39cm and become narrower as the habituation. The tau dot analysis was conducted to find the approach speed control to the target. Tau was increased linearly and tau-dot was estimated as 0.772. There were two inflection points of tau at 2sec and 0.7sec before the target. From the behaviour observation, there were two peaks of inter crick intervals at 2ms and 5ms, which means the target of the echo-location was 1.5m and 4m. These result suggest that the target recognitions of harbour porpoise was occurred at 4m and 1.5m before the target using echo-location.

漁獲物の体長組成データにもとづく資源量推定法の推定精度評価と適用
科学研究費助成事業 奨励研究(A)
1997 - 1998
松石 隆
従来、水産資源の資源量推定には、漁獲物の年齢組成を用いたコホート解析(VPA)が広く行われてきていた。この方法は、標準化が困難な漁獲努力量を用いない点で優れているが、漁獲物の年齢査定を行わなければならない点で、困難である。多くの魚種では年齢査定は耳石によって行われるが、耳石を採取するためには魚体を購入しなければならず、高価な魚種では標本数が限定された。また、年齢査定には熟練を要するため、研究者が多くの時間を割かねばならなかった。
一方、漁獲物の体サイズは、年齢組成よりも容易に得ることができる。また、漁獲規制等を行う場合、漁獲物の体サイズに応じた制限(網目制限など)を行うことが一般的であるため、年齢ごとの解析結果よりも、体サイズによる解析結果の方が直接活用することができる。
本研究では、体長によるコホート解析(LPA)、体重によるコホート解析法(WPA)を確立し、この方法を道南海域に生息するスケトウダラ、マダラ資源に適用した。
スケトウダラ資源にVPA,LPA,WPAを適用した結果、どの推定法も同様な推定結果を示し、LPA,WPAの推定結果が従来の推定結果と同様に扱えることが示唆された。
マダラ資源にWPAを適用した結果、資源量の減少傾向が見られ、漁獲開始サイズを引き上げる漁獲規制を行うことによって、確実に漁獲量の増大が期待されることが示唆された。

Long-term variations in sea condition in the subarctic circulation connected with variation in the Aleutian Low system. Residence time index of the sea ice in the Bering Sea and the Okhotsk Sea indicated decadal changes which showed negative phase between them. Current path and transport in the subarctic circulation and the transition zone also changed inter-annually. Pelagic fishes such as the salmonoid and the squids changed in their distribution and abundance with inter-annual variation in sea conditions.
Life history of the saury were discussed with modeling analysis based on catch-at-age data. Useful cohort analysis for the cods based on catch-at-weight data were proposed.

漁獲物の体長組成データに基づくコホート解析手法の開発と推定精度の評価
科学研究費助成事業 奨励研究(A)
1994 - 1994
松石 隆
【目的】従来のコホート解析は年齢別に行われるが、体長組成から年齢組成を推定したり、網目規制など体長に関する漁獲規制を検討する場合は、体長階級ごとにコホート解析を行う方が簡単であり、また体長-年齢変換に伴う誤差も除くことができる。演者らは、既に体長組成によるシングルコホート解析を提案したが、この方法では多くのパラメータを与える必要があった。そこで本講演では、Pope & Shepherd(1982)のマルチコホート解析の原理を応用した体長によるマルチコホート解析法を提案し、その精度を検討した。
【方法】まず、体長組成の推移を表現する遷移行列を作成する。個体の成長の履歴が分かる場合は直接、推移行列を推定できるが、年齢での平均体長と分散さえ得られれば、粗解析は可能である。次に、年ごとの漁獲強度を示すパラメータf_iと体長階級ごとの漁獲選択性を示すパラメータs_jを、以下の方法により推定する。最終年の漁獲量とf・sから最終年の資源量を計算し、これに遷移行列をかけ、自然死亡分をたし、前年の体長別資源量を計算する。これとf・sから前年の理論漁獲量が得られる。以上の手順を、データのある全ての年について順次行い、全期間の理論漁獲量を得る。理論漁獲量と実測漁獲量の残差平方和が最小になるようなf_i,s_jを、Apple社製Power Macintosh 6100/60上で非線形最適化法(シンプレックス探索法)を計算して求める。また、この方法の妥当性と精度を検討するために、さまざまなパラメータに誤差を導入した模擬データを作成し、設定した値と推定された値の誤差を検討した。
【結果】誤差を与えない模擬データを推定過程にかけると、設定した資源量などの値が高い精度で偏りなく推定された。また、成長曲線のまわりの偏差、成長曲線のパラメータの個体差、加入量の変動などを与えても、精度良く推定された。
