A quantitative evaluation of the pollock Gadus chalcogrammus restocking programme in South Korea

Canadian Journal of Fisheries and Aquatic Sciences
The collapse of the Korean pollock ( Gadus chalcogrammus) stock in the late 1990s is hypothesised to be due to environmental changes, overexploitation, or a combination of both factors. However, due to limited data availability, no conclusive scientific analysis is available to support any of these hypotheses.

Midwater trawl comparison study for acoustic surveys of walleye pollock (Gadus chalcogrammus) in Alaska

Midwater trawling is a critical component of acoustic-trawl fisheries surveys, and it is used to determine the species and size composition of acoustically sampled fish schools. Changes in midwater trawl gear can influence the catch, and therefore potentially bias the survey data.

Temporal changes in the diet composition and trophic level of walleye pollock (Gadus chalcogrammus) inhabiting the middle-eastern coast of Korea

Marine Environmental Research
The influences of oceanographic changes on diet composition and trophic level for pollock (Gadus chalcogrammus) inhabiting the East Sea off the Korean coast were examined based on stomach content and stable isotope analyses during 2016 and 2017. The diets of pollock consisted mainly of benthic crustaceans (particularly carid shrimps and euphausiids ...
