On the Digestive Ferments of Theragra chalcogramma (Pallas)
The fish can digest food in winter, even though the temperature of its body is nearly as low as that of the environment during that season, the difference between the two being less than 1°C. It may be expected, therefore, that the digestive ferments of the fish are more active at lower temperatures than is the case with those of warm-blooded animals ...

This study systematically investigated the differences of conventional nutrients, amino acids and fatty acids compositions among three triploid oysters (GG‐autotriploid: Crassostrea gigas♀ × C. gigas tetraploid♂, GA‐allotriploid: C. gigas♀ × C. angulata tetraploid♂, and GGA‐allotriploid: C. gigas♀ × hybrid tetraploid [C. gigas♀ × Crassostrea angulata♂]♂

Stocks of demersal fishes on the depths of 20-200 m in the northwestern Bering Sea are considered, excluding walleye pollock Theragra chalcogramma , on the data of 10 bottom trawl surveys conducted in the summer-fall of 1985-2015.

Sizes of walleye pollock (Theragra chalcogramma) consumed by the eastern stock of Steller sea lions (Eumetopias jubatus) in Southeast Alaska from 1994 to 1999 [PDF]
Lengths of walleye pollock (Theragra chalcogramma) consumed by Steller sea lions (Eumetopias jubatus) were estimated by using allometric regressions applied to seven diagnostic cranial structures recovered from 531 scats collected in Southeast Alaska ...

The match/mismatch hypothesis and the feeding success of fish larvae in ice-covered southeastern Hudson Bay [PDF]
We studied the synchronism between the seasonal occurrence of fish larvae and their prey in ice-covered southeastern Hudson Bay, Canada, in spring 1988, 1989 and 1990. Arctic cod #Boreogadus saida$ and sand lance #Ammodytes$ sp.

In recent years, skin health has become one of the leading causes of nonfatal disease burden due to the significance of the skin in the body and the ubiquitous presence of ultraviolet radiation that negatively affects skin conditions and causes skin photoaging.

Life cycles and somatic production of hyperiids in the Okhotsk and Bering Seas
Hyperiid species Themisto pacifica , T. libellula , and Primno macropa are widespread in the Far-Eastern Seas. They are an important element of trophic web in pelagic communities of these seas.

A method to improve size estimates of walleye pollock (Theragra chalcogramma) Atka mackerel (Pleurogrammus monopterygius) consumed by pinnipeds: digestion correction factors applied to bones and otoliths recovered in scats [PDF]
The lengths of otoliths and other skeletal structures recovered from the scats of pinnipeds, such as Steller sea lions (Eumetopias jubatus), correlate with body size and can be used to estimate the length of prey consumed.

Impacts of climate‐related stressors on social group cohesion and individual sociability in fish
ABSTRACT Group‐living in animals comes with a number of benefits associated with predator avoidance, foraging, and reproduction. A large proportion of fish species display grouping behaviour. Fish may also be particularly vulnerable to climate‐related stressors including thermal variation, hypoxia, and acidification.
