Winter Diets of Pacific Salmon in the North Pacific
Fisheries Oceanography, Volume 34, Issue 6, Page 118-138, November 2025.ABSTRACT The winter feeding ecology of Pacific salmon and Steelhead trout in the North Pacific Ocean was investigated, with a focus on species‐specific diets and interannual and spatial variability in diet composition. We used results from the 2022 International Year of the Salmon Pan‐Pacific Expedition to examine diet composition across the North ...

Model tests of high speed midwater trawls with large meshes.
NIPPON SUISAN GAKKAISHI, 1990 Midwater trawling technology has become important since the early 1980's for harvesting underutilized fast swimming fish. Developmental work has involved fishing trials with full scale midwater trawls by the Japan Marine Resources Development Center (JAMARC).

Characteristics of Dynamic Control of Midwater Trawl System in Field Experiments.
NIPPON SUISAN GAKKAISHI, 1994 In order to investigate the characteristics of dynamic control of a midwater trawl, a field experiment was conducted by FRV “SINYO-Maru” of Tokyo University of Fisheries. The parameters of the midwater trawl being towed were measured with a SCANMAR system and a self-recording underwater load-depth meter.

Environmental DNA for Aquatic Monitoring: Impact of Diel Vertical Migration
Environmental DNA, Volume 7, Issue 5, September–October 2025.Environmental DNA concentrations are affected by animal behavior, such as diel vertical migration (DVM), which has repercussions for designing eDNA sampling strategies. The effect of DVM was identified for hake using samples from the Bay of Biscay and corroborated using theoretical Lagrangian particle‐tracking modeling.
