Japanese, Research institution, ハタハタActoscopus japonicusは，朝鮮半島東岸から沿海州，サハリン，カムチャッカを経て北米まで北太平洋北部に広く分布しており，水深450m以浅の大陸棚に生息する冷水性底魚類である(草刈，1994)。日本海には秋田県の牡鹿半島付近を産卵場とする「日本海北部系群」と韓国の東岸を産卵場にする「日本海西部系群」の2郡が存在している(京都府立海洋センター，2005)。藤原ら(2011)の報告によると，鳥取県のハタハタは日本海西部系群に属し，本系群は近年，我が国周辺における本州の漁獲量の半分以上を占めており，資源状態は高水準で横ばいと判断されている。また，本県においてハタハタはかけまわし漁法(倉長，2010)で漁獲されており，漁期は9月から翌年の5月までである。雌雄とも2歳から成熟過程に入り(三尾，1967)，漁場に現れる満1歳の2～3月頃には体長100mm前後，2歳で体長150mm，3歳180mm，4歳200mm前後と見られ，メスの方がやや大きめのサイズになる(藤原ら，2011)。小型個体は市場価値が低く，さらに再生産の点で未成魚の保護が将来の資源保護に繋がることから，未成魚の漁獲を防ぐ必要がある。そのため同県水産試験場では，これまでにハタハタに対してコッドエンドの網目規制による管理を検討してきた(倉長ら，1999; 倉長，2010)。こういった小さな個体の混獲を減少させる方法としては，コッドエンドの網目拡大が有効であるが，その効果を定量的に評価するためには，網目選択性を求める必要がある。そこで，本研究では倉長(2010)と同様のデータを用いて，同かけまわし網における選択性のマスターカーブの推定を行い，本漁業における適切な目合について定量的に検討することを目的とした。

Japanese, Research institution, A seawater sampling system using underwater towed body was developed to obtain the water continuously. The systemwas composed of two towed bodies, which are vertically linked each other, to sample water in different layers. The range oftowing speed and target depth of the system were planned as up to 5.0 kt, and 10.0 to 20.0 m, respectively. At first, hydrodynamiccharacteristic of the towed body was examined using CFD analysis, and then the towing depth under the planned speedwas predicted dynamically. Finally, the validity of the towed body was confirmed at sea experiment. In the sea experiment,the depth of each towed body was measured changing towing speed on both conditions with hose to pump-up water and withoutit. The depth at the case with hose decreased by about 60 percent to compared with the case without hose. The depth of thelower side body with hose reached 20.0 m when the towing speed was 3.3 kt. Based on these results, it was estimated that thetowing speed to attain the depth of 20.0 m will increase to 5.0 kt by decreasing hose diameter from 18.0 mm to 8.0 mm, orincreasing each body weight to 150.0 kg.

English, Scientific journal, To clarify the process that leads to large-angle inclinations or even the capsizing of fishing boats, it is useful to be able to track dynamic changes in ship motions. These motions during fishing operations are not static, they change from moment to moment according to the fishing process, and it is important to understand the characteristics of the motions during each fishing operation process. To this end, in this study we focused on conducting a wavelet analysis to simultaneously estimate the time and frequency characteristics of the motions. We conducted a wavelet analysis of motion data obtained from a 160GT offshore trawler under standard running conditions and during Danish seine trawling. From the result obtained, we were able to accurately estimate motion characteristics as conditions changed during the fishing process. Periodical changes in motion were observed as a result of the resonance between the ship motions and the waves that were encountered.

English, Scientific journal, A study of coastal fishing boats (small purse seiners) was made in North Sulawesi province, Indonesia. The goal of this study is to clarify the rolling motion under fishing operation of the small purse seiners. First of all we examined the boat form of the purse seiners and practical conditions of rolling motion under fishing operations. Based on the data, the characteristics such boat's stability and rolling motion under fishing operation were calculated. The results of the analysis are as follows: the boat types were relatively slim around the hulls, and the boats had the round shape under water, and a boat still used by fishermen had extremely poor stability, and the roll angle increased remarkably in stage when the boat crossed the wave direction with hauling process, and results of Wavelet analysis showed that the purse seiners used in North Sulawesi had the same characteristics of rolling motion, and wavelet coefficients became large in hauling process.

Fishery income fluctuation with changing social situation and selecting fishing ground, in the Japanese coastal squid jigging fishery
Osamu Tamaru, Kazushi Miyashita, Nobuo Kimura, Yasuzumi Fujimori, Hideo Takahara, Teisuke Miura
Bulletin of Fisheries Sciences, Hokkaido University, 62, 3, 75, 82, 北海道大学大学院水産科学研究院, 2012
English, Research institution, In recent years in Japan, falling fish prices and rising fuel costs have worsened the economic conditions for many fisheries-dependent households. Many fishermen select the fishing ground in which they anticipate they can maximize their total catch, even when such grounds are far from their home harbor. As a result, fishermen have the potential to select a fishing ground in which they do not maximize their income. Especially the Japanese coastal squid jigging fishermen need to develop energy-saving squid jigging fishery practices, because of the high fuel consumption in comparison to other fisheries. By using the Management Simulation Method, we show that income fluctuations are caused by various factors. We used social factors and fishing ground factors in this simulation. According to the simulation results, small changes in social and fishing ground situations can result in changes in selection of the optimal fishing grounds. We conclude that the selection of fishing grounds by fishermen based only on their own knowledge and/or intuition might not result in choices that maximize their income, and it is necessary to develop objective methods to choose the fishing ground in which they can maximize their income.

Japanese, Danish seine trawl which is major offshore trawler in Hokkaido is regarded as having high risk of the resonance due to the characteristics of its operation method. However, as there are few study of ship motions in fishing operation, the actual condition is not clear. In this study, we perform estimating ship stability and the characteristics of ship motions by frequency analysis based on the data of ship motion. In the result, the ship stability decreased at short wave length and the resonance occurred between the natural period of rolling motion and the encountered period of wave in hauli...

English, A series measurement of coastal fishing boats (small purse seiners) has been made in North Sulawesi province, Indonesia. The goal of this study is to clarify the physical characteristics of the small purse seiners in North Sulawesi. First of all we examined the boat form of the purse seiners and practical conditions under fishing operations. Based on the data, the characteristics such coefficient of fineness and the boat's stability were calculated. Typical fishing boats in Indonesia have conventional round hull shapes with a long bar keel. Purse seiners in North Sulawesi have different characteristics in every region, especially for principal dimensions and boat's designs. The results of the analysis are as follows: the boat types are relatively slim around the hulls and have the round shape under water, stability values are relatively small, and the cluster based on the principal dimensions and the coefficient of fineness has been categorized into two groups and three classes.

Japanese, To clarify the difference of fish species attraction to artificial fish reefs according to the structure of fish reef units, fish catch experiments were performed at different reef units and a control area arranged in Furubira-cho offing, Hokkaido. The attraction effect of the fish reefs for each fish species due to differences in structure was ascertained by use of principal component analysis (PCA). As a result, accumulated contribution ratio of the directivity for the element of fish reef unit accounted for 89% and the main characteristics were explained by just four components. It was suggested that the characteristics of the attraction effect for each fish species were different among the types of the fish reefs.

Japanese, A trousers-type framed midwater trawl (T-FMT) was developed for the simultaneous sampling of plankton and micronekton, which allows the use of two kinds of mesh sizes at the same time. This paper describes the performance of T-FMT in the survey of plankton and micronekton. In addition, the estimation of size selectivity for these small creatures was conducted by using the SELECT analysis expanded for a sub-sample from the trousers trawl experiment. The experiments for plankton and juvenile walleye pollock were conducted offshore of Usujiri, Hokkaido. Three kinds of codends were prepared: tw...

日本航海学会論文集, 116, 116, 243, 248, Japan Institute of Navigation, 25 Mar. 2007, [Peer-reviewed]
Japanese, Fishing boats for the scallop cultivation in Hokkaido, Japan are small less than 10GT and harvest time of scallop is in winter season. As the fishing boats are moored to the big scale scallop cultivation facilities to do fishing work, the ship inclines about 6〜10 degrees into mooring side. Then, we aimed to develop the mooring device to reduce ship motion. If the large amplitude motion would generate under such inclining condition, the ship would be dangerous for capsize. In this study, we made the mooring device model for the fishing operation, that installed oil damper as absorber for ship motions. And we conducted model experiments under regular waves. As a result, the effect of the motion reduction was suggested by the use of the proposed mooring device.

Japanese, Maintenance of fishing ports have been advanced till today for the purpose of keeping for safe mooring of small fishing boats or improvement in cargo work efficiency. However, occurrence of mooring disasters of small fishing boats is still reported and it has been a serious problem. Then, in this study, we made experiments using a model ship based on the actual condition of the mooring method and considered interrelation between the ship motion and tension of mooring lines. In addition, we suggested safe mooring of small fishing boats such as how to take a mooring line and the mooring method.

Squid Material Flow, Zeroemission Technology and the Nitrogen balance in Japan
MIURA Teisuke, WATANABE Kazuhito, SHIODE Daisuke, FUJIMORI Yasuzumi, SHIMIZU Susumu

Japanese, The squid raw material supply system models in Japan and in the case of a local city Hakodate were investigated from the concept of nitrogen balance. The amount of nitrogen in imported squid material was 2, 755 tons and that in exported all products made from squid material was 2, 311 tons. As the result, 409 tons nitrogen remained in the area of Hakodate. Only the nitrogen of 62 tons (2.2% of the input) was abandoned as a waste in the area of Hakodate except the nitrogen of amount of 347 tons that man eats. This value shows that Hakodate is a region that circulates well from the respect of squid's nitrogen balance. There is a problem in the processing of the feed maker of squid's internal organs by charge. It means that squid's internal organs are not evaluated. In Japan, the industry that relates to the squid imports a large amount of raw materials as well as other food industries, and consumes the most domestically. The entire squid import has only 21, 000 tons to compare with that of export for 730, 000 tons in 1997. It means nitrogen 18, 200 tons input and 1, 090 tons output. The nitrogen of 17, 100 tons stays domestically as a result. It is necessary to promote the development of the commodity which can be consumed in the foreign countries or which can be exported to improve this state.

Japanese, This paper describes the reactions of freshwater fishes to He-Ne laser light and discuss herding effect of moving laser screen. The indoor tank experiments were conducted to examine herding effect at different fish numbers (10, 20 and 30 fish) and different species (Japanese dace Tribolodon hafronensis, carp Cyprinus carpio and rainbow trout Oncorhynchus mykiss). In outdoor tank, it was attempted to herd rainbow trout at different moving speeds of laser screen. Laser temporally dispersed fish school, and then fish again swam in school avoiding the laser. Thereby laser can drive fish into an area of tank. Fish are however considered to leam to escape through laser screen, since herding effects decreased, following repeated exposure to the stimuli of laser screen. Laser could herd fish more effectively in the dark than in the light at the indoor tank experiment. The larger fish number of Japanese dace was, the sooner laser screen could herd. Moreover, the herding effect was different among species. The proportion of herded rainbow trout decreased over 25 cm/s of laser screen moving speed. It is therefore resulted.that the herding effect depends on several factors e. g. fish school behavior and swimming performance.

Saeki Kimiyasu, Kimura Nobuo, Fujimori Yasuzumi, Yasuma Hiroki, Memoirs of the Faculty of Fisheries Sciences, Hokkaido University, 55, 1, 107, 132, Dec. 2013
In many commercial operations of set net fishery and trawl in Japan, fish catch unloaded from boats are promptly sorted anddisplayed for an auction at a fishing port. This work is achieved with machines and by hand. There have been existed manuallabor and dangerous operations. However, the system of work is so empirical and complicated because of variety of species offish catch and its day-by-day fluctuation. This remarkable feature prevents worksite from improvement. In this study, based onexisting work analysis technique, systematic technique of work process description for improvement of caught fish handling isnewly proposed. Practicality of this technique is proved through the application to two worksites in Japan. Process chart anddescription derived from this technique would contribute to improvement of occupational health and safety at fishing ports., Faculty of Fisheries Sciences, Hokkaido University, Japanese, Report research institution

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。

This study investigated a method to improve selectivity of shrimp pot aiming to protect the stock of Coonstripe shrimp Pandalus hypsinotus in the Funka-Bay, Hokkaido. It was found that small individuals were particularly active at night from the water tank experiment to investigate the behavior and diurnal activity. This suggested mesh size expansion and the installation of escape gap on pot for exclusion of small shrimp would be effective.
The mesh selectivity of the pot was estimated by water tank experiments, and it was elucidated that 35 mm mesh size was suitable to protect individuals with 20 mm carapace length which correspond to the size of recruitment. Also, we confirmed that the circular escape gap with an inner diameter of 25 mm was expected to exclude the carapace length of 30 mm which correspond to the size after sexual conversion.

01 Apr. 2012 - 31 Mar. 2017
Yamaguchi Atsushi
From both viewpoints of fisheries and oceanography, zooplankton size structure is a prime important factors to determine their flux. Concerning zooplankton size spectra, following four topics were evaluated: 1. Spatial distribution of neighboring water of Japan, 2. Geographical distribution in the North Pacific, 3. Vertical distribution down to greater depths covering whole North Pacific, 4. Yearly changes (1946-2012) in the Chukchi Sea.
Concerning energy transfer within the zooplankton community, bottom-up control and high energy transfer efficiencies were observed for the western subarctic Pacific. In the western subarctic Pacific, zooplankton community was dominated by large-sized copepod Neocalanus spp. For vertical distribution, regional differences in zooplankton community were recognized even in the deep-sea down to 2000 m. Inter-annually, zooplankton biomass in the Chukchi Sea increased through 1946-2012.

A drift net series consisting of several net panels of different mesh sizes was used to investigate pelagic fish resources in the waters around Japan. First, mesh selectivity of research driftnet for Japanese sardine was estimated. The relationship of body girth against the mesh perimeter suggested that Japanese sardine was efficiently caught by the capture process of “wedged” or “gilled”. Next, selection curves of research driftnet for chub mackerel were estimated in the two periods of June-July and September-November. Fish caught in June-July had slightly greater fork length than those in September-November, and they also had a lower condition factor implying a smaller body girth following spawning. The pooled relative catching intensity steeply declined for fish with fork length over 300 mm at the current mesh combination, and the addition of two panels with larger mesh sizes (82 and 106 mm) kept a constant intensity for fish below 350 mm fork length.

This study aims to develop a new method of measuring the size of fish on the image from camera. The tank experiment was conducted using a digital camera and laser unit that generate flat beam. Further, sea experiment was done preparing a measuring system installed to watertight case that has capability of 300 m sea depth.
The measurement error was 4 % in mean and up to 5 % in the tank experiment. In the sea experiment, the measuring system was hanged underwater from the ship. The fish that recognized as walleye pollock was observed. The estimated length accorded with the size of walleye pollock distributed in the experimental area.

In coastal area, Sargassum spp., Zostera spp. and Laminaria spp. forms dense vegetation community, which are called as seaweed bed, seagrass bed and kelp bed. In this study, we estimated the characteristics and the wave shapes of acoustic intensity of these beds, and then we developed the discriminate method of these beds by acoustic technique using the characteristics. In the result, it was suggested that the discrimination of the beds is possible using a two-stage approach. The first stage is the discrimination of the area backscattering (Seaweed bed; -33.3~-57.0 dB, Seagrass bed; -39.2~-66.1 dB, Kelp bed; -59.8~-74.3 dB). In the second stage is the discrimination of the wavelet coefficient of Lv. 4 (Seagrass bed; 12000-39000, Kelp bed; 3000-12000). This method may allow better biomass estimation of these beds by acoustic technique.

HU Fuxiang, TOKAI Tadashi, SHIODE Daisuke, HUJIMORI Yasuzumi
In this research, the new multi-sampling trawl with automatic net opening and closing control system was developed to sample pelagic juvenile fish. A net-release controller is used, which not only controls the net release mechanism but alsorecords the net depth, temperature and flow rate during net towing.
The field experiment was carried out using training ship Shinyo-maru, and RV Kaiyo-maru in Sagami Bay. From the results, the net maintained almost constant depth under towing speed from 2. 0-4. 0kt, and the nets were surely opened/closed smoothly by the command from the controller. The newly developed multi-sampling trawl is considered to be suitable for quantitative layer sampling of juvenile fish.

It is very important that we develop multi-dimensional sensing in combined with satellite remote sensing, underwater remote sensing and direct survey to predict when, where and how much are marine living resources available. Objectives of this study are to develop methodology of multi-dimensional sensing of marine living resources and their environment and to monitor three-dimensional distributions of Japanese common squid and three dimensional environment using acoustic with towed body transducer and real-time towing CTD system with satellite images. Major results are as follows :(1)Observ...

イカ残滓の有効利用技術の現状
我々の研究グループが行っているイカゴロを釣の人工餌料として活用する試みもその一つである。鹿児島大学水産学部との協力で、キンメダイやメヌケなどを対象に近海・沿岸漁業での応用可能性について調査を始めた。また、北海道大学水産学部では、ハワイ沖漁場でマグロの延縄の試験操業を行い、代替飼料としての可能性を調査した。遠洋漁業の代表とも言えるマグロ延縄漁業は、年間、6万トンほどの天然餌料(イカ、サンマなど)を消費している。一方、遊魚の餌としての利用も始まった。これらの利用方法が確立すれば、道南のイカゴロ問題解決策の重要な決め手となる。青森では、以前からイカ墨の抗腫瘍性の研究が進み、イカ墨利用の各種食品の開発が進んだ。また、イカの皮から染色材を抽出する研究も進行中である。北大工学部では、イカの骨からとったキチンを利用して人工皮膚の研究も進んでいる。
現在進行中の企業化プラン(イカ墨染めの特産品化)
イカゴロから釣餌を造る過程で廃棄されるイカ墨を利用して、特産品(アート・工芸品)の開発を試みる計画である。釣餌を製造する株式会社コーノがその生産過程でイカ墨を排出する。これを使って蕃伎社を支援して最終的に函館市の特産品化を目指すものである。
今後の計画
函館市商工観光部の呼びかけでイカの加工から消費にいたる過程で関わる地域の関係者を集め、現状の課題や今後の産業起こしを目指して、相互に情報・意見の交換を行うことを目的に、仮称“いかゼロエミッション調査研究会"の発足準備が進められている。参加者は北海道大学水産学部、道立工業試験センター、水産加工組合、関連企業、自主研究グループ、市関係部局が中心に、平成11年度、年5回程の会議が予定されている。
以上、今年度は当初計画していたイカ残滓有効利用技術の現状把握に加えて未来型技術の提案について、ならびに来年度に向けての具体的な成果を得ることができた。
