Characterization of salmon‐foraging harbor seals (Phoca vitulina) in the Erimo region, Hokkaido, Japan, using finite mixture models

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

The Impacts of Marine Heatwaves on Economic Fisheries in Adjacent Sea Regions Around Japan Under Global Warming

Fishes
Climate change has significantly affected marine fisheries. In recent years, marine heatwaves (MHWs) have intensified concurrently with increasing sea surface temperature (SST), particularly along the coast of Japan in the Northwest Pacific. Although the

Overwintering Fish Community in Ice‐Covered Environments in Hokkaido, Japan, Inferred From Environmental DNA

Environmental DNA, Volume 7, Issue 2, March/April 2025.
Using fish eDNA metabarcoding, we successfully described an overwintering fish community in ice‐covered environments. eDNA data indicated that the dominant species were Clupea pallasii in the lagoon and Tribolodon spp. in the inlet river. Our findings suggested that the eDNA technique is useful for studying ice‐covered areas and could provide new ...

Simple visualization of fish migration history based on high‐resolution otolith δ18O profiles and hydrodynamic models

Limnology and Oceanography Letters, Volume 10, Issue 1, Page 101-112, February 2025.
Abstract Oxygen‐stable isotope (δ18O) in otoliths has been useful to infer marine fish migrations. However, because otolith δ18O is affected by two parameters, temperature and δ18O of ambient water, its interpretation becomes challenging when neither of them is constant.

Feeding habits of splendid alfonsino Beryx splendens in the vicinity of Kuroshio, the south of Japan

Fisheries Oceanography, Volume 34, Issue 1, January 2025.
Abstract Gut contents and nitrogen isotope ratio (δ15N) analyses were conducted on splendid alfonsino Beryx splendens collected in the vicinity of Kuroshio from May 2015 to November 2016 (n = 708) to identify their feeding habits in the Western North Pacific.

Leveraging ecological indicators to improve short term forecasts of fish recruitment

Fish and Fisheries, Volume 25, Issue 6, Page 895-909, November 2024.
Abstract Forecasting the recruitment of fish populations with skill has been a challenge in fisheries for over a century. Previous large‐scale meta‐analyses have suggested linkages between environmental or ecosystem drivers and recruitment; however, applying this information in a management setting remains underutilized.

Migration patterns of the Japanese sardine in the Sea of Japan by combining the microscale stable isotope analysis of otoliths and an ocean data assimilation model

Frontiers in Marine Science
The Japanese sardine (Sardinops sagax melanostictus) is a small pelagic fish found in the Sea of Japan, the marginal sea of the western North Pacific. It is an important species for regional fisheries, but their dispersal and migration patterns during ...

Growth–feeding linkage in small pelagic fish larvae in the Kii Channel, Japan

Fisheries Oceanography, Volume 33, Issue 6, November 2024.
Abstract The linkage between growth rate and feeding success has been shown to strengthen the effects of early growth rate on later growth rate in the early life history of fish. However, the growth–feeding linkage largely remains to be tested at the individual level within the same populations/cohorts.

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.
