A key aspect of foraging ecology research is understanding how predator foraging behavior and success are influenced by variation in prey resources. For northern fur seals (Callorhinus ursinus), an understanding of predator-prey relationships is critical to help identify potential causes for the unexplained population decline in Alaska. To examine ...

AbstractData on the spatial distribution of the Walleye Pollock, Theragra chalcogramma, and the conditions of the habitat off the southern Kuril Islands in the spawning season of 2015 and the feeding season of 2016 are provided in this report. In the spring, most walleye pollock are distributed more evenly over the shelf and continental slope to a ...

In 2020, the developing COVID-19 pandemic disrupted fisheries surveys to an unprecedented extent. Many surveys were cancelled, including those for walleye pollock ( Gadus chalcogrammus ) in the eastern Bering Sea (EBS), the largest fishery in the United States. To partially mitigate the loss of survey information, we deployed three uncrewed surface...

Food availability is a key concern for the conservation of marine top predators, particularly during a time when they face a rapidly changing environment and continued pressure from commercial fishing activities. Northern fur seals (Callorhinus ursinus) breeding on the Pribilof Islands in the eastern Bering Sea have experienced an unexplained popul...

The Alaska Climate Integrated Modeling (ACLIM) project represents a comprehensive, multi-year, interdisciplinary effort to characterize and project climate-driven changes to the eastern Bering Sea (EBS) ecosystem, from physics to fishing communities. Results from the ACLIM project are being used to understand how different regional fisheries manage...

AbstractData on age of the walleye pollock Theragra chalcogramma (Pallas, 1814) from the eastern Sea of Okhotsk, determined by otolith analysis, are considered. A comparison of the age–length relationships, as inferred from variations in modal body size of fish of strong year-classes and from otolith-based age estimates, has shown no significant di...

Walleye pollock (Gadus chalcogrammus) is one of the popular fish species in Korea and known to frequently harbor anisakid nematodes. Despite many papers regarding walleye pollock having been published, there is no information on the prevalence and distribution of anisakid nematodes from walleye pollock in Korean waters. We investigated 716 walleye ...

The walleye pollock (Gadus chalcogrammus) population in Korean waters had thrived until the mid-1980s, but this fish population has been depleted since the late 1990s. Limited data and lack of ecological research about the population prevented us from revealing the mechanism or material cause that resulted in the population’s collapse. Instead, we ...

In tissues of the walleye pollock Theragra chalcogramma the dry matter content averages 18.5%. The lipid content of the raw material is 0.7%, the protein content is 15.3%, carbohydrates are 0.6%, and ash is 1.3%. The average calorie density is 940 cal/g wet weight and 5080 cal/g dry weight. The dry matter content of gonads varies within 14.9–28.0% ...
