Spatial distribution and abundance of walleye pollock are considered for the northwestern Bering Sea in the summer-fall of 2020 on the data of echo-integration trawl-acoustic survey. The pollock aggregated mostly in the shelf areas with positive or close

Foraging responses of black-legged kittiwakes to prolonged food-shortages around colonies on the Bering Sea shelf. [PDF]
We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts in habitat use with direct implications for population trends.

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 ...

Catch distribution and size-age structure of walleye pollock in the Chukchi Sea are considered on the data obtained in surveys conducted by TINRO in 2018–2020. The age of pollock was determined by otoliths.

ABSTRACT This study aimed to quantify the cannibal‐prey size relationship using morphometric regression models and to establish an effective size‐grading strategy to prevent cannibalism. A total of 15,000 juveniles at 73 days post‐hatching (DPH) were reared in a circular tank (approximately 12 tons) operated under a flow‐through seawater system at 26.0

Abundance and biomass of walleye pollock Theragra chalcogramma in the Bering Sea exceeded the mean values in 2015 owing to the high-abundant year-classes of 2008 and 2012 and several medium-abundant year-classes (of 2006, 2009-2011, 2013, and 2014).

Muscle Contraction Time of Captured Walleye Pollock Theragra chalcogramma.
The muscle twitch contraction time of Walleye pollock Theragra chalcogramma was measured in relation to fish size and muscle temperature, on board a Northern trawler in the Okhotsk Sea. The contraction time was defined as the time period from the electric pulse of 2ms wide and 5-20V, to the peak of muscle twitch contraction.

Abundance and species composition are investigated for demersal fish at the oceanic side of southern Kuril Islands on the data of the bottom trawl survey in the depth range 100-1400 m conducted in the spring of 2009 (for the first time at the continental

Incorporating Climate Change Impacts Within Harvest Strategies: An Overview of Approaches
ABSTRACT Ensuring that harvest strategies are robust to climate change is a top priority for many fisheries jurisdictions globally. This is because climate change is altering ecosystem structure and the productivity of marine species. We outline a range of approaches for incorporating climate change impacts within harvest strategies, including how a ...

This study was to investigate the in vitro antimicrobial activity of fish protein hydrolysate (FPH) against Vibrio harveyi, V. anguillarum, and V. scophthalmi, as well as the nonspecific immunity, intestinal microbiota, and disease resistance to V. harveyi in turbot. FPH was prepared from Pollock.
