Feeding of walleye pollock and its feeding base in the Chukchi Sea in summer-autumn period

Известия ТИНРО, 2023
Data on feeding of walleye pollock <i>Gadus chalcogrammus</i> (3–70 cm long) in the Chukchi Sea in summer-autumn of 2017–2020 are presented. The food base includes zooplankton, benthic invertebrates and fish. The juveniles in the northwestern

Effects of dietary lipid level on growth performance, feed utilization, fatty composition and antioxidant parameters of juvenile walleye pollock, Gadus chalcogrammus

Aquaculture Reports, 2021
We evaluated effects of dietary lipid level on growth performance, feed utilization, fatty acid composition, plasma chemistry, and antioxidant responses in juvenile walleye pollock (Gadus chalcogrammus). Two-hundred forty juvenile pollock averaging 4.4 g

Influence of hydroacoustic noise from vessel on echo integration estimations of fish stocks and catchability of accounting trawl (on example of walleye pollock in the Okhotsk Sea)

Известия ТИНРО, 2017
Previously, catchabilty of walleye pollock was estimated for the accounting trawl RT/TM 57/360 by results of acoustic measurements of fish density in the towed layer under fishing vessel.

Seawater carbonate chemistry and hatch size and larval growth of walleye pollock (Theragra chalcogramma)

, 2013
Rising atmospheric concentrations of CO2 are predicted to decrease the pH of high-latitude oceans by 0.3–0.5 units by 2100. Because of their limited capacity for ion exchange, embryos and larvae of marine fishes are predicted to be more sensitive to ...

Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea [PDF]

We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye
