Comparison of growth, behavior and lipid concentrations of walleye pollock Theragra chalcogramma larvae fed lipid-enriched, lipid-deficient and field-collected prey

While growth and survival of marine fish larvae in the sea may be dependent on prey type, size and concentration, nutritional quality of prey may also play an important role. This study investigates the relationships of lipid content of prey with growth,

Some aspects of biology and fishery of walleye pollock Theragra chalcogramma in the southwestern Chukchi Sea relative to the size and age structure

Известия ТИНРО, 2022
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.

Preventive Management of Cannibalism by Size‐Grading in Juvenile Red‐Spotted Grouper (Epinephelus akaara)

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
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

Assessment of stock, spatial distribution, and recruitment of walleye pollock in the northern and eastern Bering Sea

Известия ТИНРО, 2016
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).

Incorporating Climate Change Impacts Within Harvest Strategies: An Overview of Approaches

Fish and Fisheries, Volume 26, Issue 5, Page 942-956, September 2025.
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 ...

Characteristics of trypsin from the pyloric ceca of walleye pollock (Theragra chalcogramma) [PDF]

Food Chemistry, 2008
Trypsin was purified from the pyloric ceca of walleye pollock (Theragra chalcogramma) by gel filtration on Sephacryl S-200 and Sephadex G-50. The final enzyme preparation was nearly homogeneous in sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS–PAGE) and the molecular mass of the enzyme was estimated to be 24 kDa by SDS–PAGE.

Exploring Antibacterial Activity of Fish Protein Hydrolysate In Vitro Against Vibrio Strains and Disease Resistance to V. harveyi in Turbot (Scophthalmus maximus)

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
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.
