• Human dimension of small-scale fisheries and Steller sea lion conflict in Hokkaido coastal water, Japan: exploring perceptions and attitudes between fishermen groups

  Frontiers in Marine Science, 17 Dec. 2025
  Scientific journal, The conflicts between pinnipeds and coastal fisheries are harmful for both pinniped conservation and fishermen’s livelihood. In Hokkaido, Japan, negative interactions between Steller sea lions (SSL) and gillnet and set net fisheries have been an issue for decades. Damage control measures have been implemented, but little is known about fishermen’s perception of the conflict. The recent increase in human dimension research has demonstrated the necessity of this approach in conflict mitigation and resolution. This study aims to clarify the fishermen’s perception of and attitude toward SSL and mitigation methods, and explores the context in which fishermen face this conflict. We conducted 29 on-site interviews with fishermen in several fishing villages along the Sea of Japan and Sea of Okhotsk coasts. We found that most fishermen approved population control as a damage control measure and considered it the only effective method. However, they were open to the development of non-lethal methods. Gillnet and set net fishermen’s perception of SSL's ecological role was more complex than just a threat to their catch. Gillnet fishermen showed a more negative attitude toward SSL compared to set net fishermen. We conclude that fishermen need solutions not only to mitigate the conflict with SSL but also to maintain a decent livelihood while practicing their fishing activity. Our findings explored the larger context surrounding conflict with wildlife and provided valuable information for developing strategies to coexist with wildlife.

• Relationship between body density and feeding habit among flatfishes

  Journal of Fish Biology, 27 Mar. 2025, [Peer-reviewed]
  English, Scientific journal, AbstractThe body density of 16 species of flatfish was measured. Their density varied, ranging from 1.011 to 1.074 g cm−3, with benthic feeders tending to have the highest values, followed by mixed feeders and then pelagic feeders. Greenland halibut, Reinhardtius hippoglossoides, had the lowest value (1.022 ± 0.0052 g cm−3), below the density of seawater (1.026 g cm−3), indicating that this species can swim away from the sea floor with low‐energy costs. In this manner, low body density may contribute to pelagic feeding. Further study of lipid content and other body characteristics of each flatfish is expected to elucidate their evolutionary traits more clearly.

  Japanese, Research institution, To reveal the oceanic environmental changes in and around Shiretoko, a UNESCO World Heritage Site, we established coastal monitoring networks for marine environments and conducted shipboard observations and mooring observations in seasons and areas where observations were limited. This overview focuses mainly on the observations of physical oceanography by the ongoing coastal monitoring, as well as shipboard and mooring observations. The obtained data is anticipated to enhance our understanding of the short-term, seasonal, and longterm variations in the Shiretoko region.
• Effects of Temperature on the Gastric Evacuation Rate and Maintenance Ration of Adult Pointhead Flounder Cleisthenes pinetorum
  Sango Nishio; Orio Yamamura
  Journal of Applied Ichthyology, Jan. 2024, [Peer-reviewed]
  English, Scientific journal, We investigated the gastric evacuation rate (GER) and maintenance ration (MR) for the adult pointhead flounder Cleisthenes pinetorum (77–421 g) at 4°C, 9°C, and 14°C which reflect the bottom, middle, and surface temperatures of their habitat in early summer. GERs were obtained from gravimetric experiments with 34 flounders fed juvenile walleye pollock Gadus chalcogrammus as prey. A 169‐day feeding experiment for 67 pointhead flounders fed krill Thysanoessa inermis was undertaken to measure MR. The effects of a 10°C temperature increase (Q10) on the GER and the MR were 6.55 and 2.04, respectively, indicating that the effect of temperature was greater on GER than on MR. As a result, the differences between the GER and MR, indicating the maximum amount of food ingestible for growth, were 2.8 and 30.7 cal·g−1 day−1 at 4 and 14°C, respectively. The water temperature on the sea floor generally remained at <4°C from winter through summer, but exceeded 10°C in the surface layer of Funka Bay, where pointhead flounders were sampled. Therefore, their growth rate should be considerably limited if they remain in the bottom layer. The unique ecology of this species among the flatfishes of floating from sea floor and feeding at pelagic zones may represent a strategy to compensate for the physiological limitation of growth at low temperatures.

  Japanese, The Japan Pacific population of walleye pollock, which is distributed widely along the Pacific coast of northern Japan, is one of the most important fishery resources in Japanese waters. Spawning of the population occurs in winter adjacent to the mouth of Funka Bay. Pre-settlement juveniles have been found to be migrated from the Funka Bay area to the southeastern coast of Hokkaido (Doto area) via the coast of Hidaka Bay by their first autumn. Thus the Doto area, where they settle and remain for several years, is an important nursery ground for juvenile pollock; they spend 3-5 years while they are immature in the Doto area. By the age of 3 to 5, pollock mature and migrate back to the Funka Bay spawning ground. After spawning, the adults return to the Doto area to recover taking advantage of the high prey abundance. Such a life history capitalizes on the features of the two adjacent areas, the mouth of Funka Bay and the Doto area, as a spawning ground and a feeding ground, respectively.

  2020年6月に予定していた調査がCOVIDで中止になったため，2021年5月に観光船をチャーターし，調査を実施した．また，2019年度に実施したおしょろ丸調査のデータ解析を進めた．目視調査で最も多く記録された海鳥はハシボソミズナギドリであった（6月29日知床岬沖で65,000羽）．鯨類では，イシイルカ，シャチ，マッコウクジラ，ミンククジラが知床半島の東西で見られたが，ナガスクジラは西側のみで見られた．音響調査により，プランクトンの反応を示す120 kHzの周波数では，能取岬沖と知床半島周辺の東西で大きな反応が見られた一方，魚類の反応を示す38 kHzの周波数では知床半島東側に大きな反応が見られた．CTD-LADCPとXBT観測からオホーツク海沿岸は宗谷暖流水が分布し，根室海峡北部にも海面から水深150dbar付近まで，既に入り込んでいることが明らかになった．また，植物プランクトンの優占分類群では，宗谷暖流が卓越する沿岸域および中冷水では珪藻類，沖合域ではナノ鞭毛藻類と，海域により異なっていた．このような海域差は，水塊間の栄養塩および鉄濃度の違いに起因すると考えられた．動物プランクトンバイオマスには，中型動物プランクトンのカイアシ類Metridia okhotensisが優占し，この種の排泄する糞粒が鉛直的な物質輸送に大きく貢献することが示された．11地点で実施したMOHTネットによる採集では，斜里沖陸棚斜面上部の2地点（B2およびB3）でソコイワシ科に属する魚類マイクロネクトンのまとまった採集がみられた．しかし，両地点は必ずしも鯨類や海鳥類との高密度域とは一致しておらず，これら高次捕食者の分布との関連が薄い可能性が示された．
