Питание сайки Boreogadus saida в Беринговом и Чукотском морях

open access: yesИзвестия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2013
В осенний период сайка в Анадырском заливе питается в основном амфиподами и копеподами. У более крупных экземпляров амфиподы в рационе частично заменяются креветками. Так же как в Анадырском заливе, в Чукотском море сайка поедает в большом количестве амфипод, различных креветок и копепод.

Growth of Polar cod (Boreogadus saida) in the Barents Sea

open access: yes, 1990
Observed length-at-age, and backcalculated lengths based on otolith measurements, from samples of polar cod collected in the Barents Sea in autumn of 1987 to 1989, were analysed. An increase in individual length growth of one-year-olds was observed from 1987 to 1989.

Transcriptome responses to benzo[a]pyrene in liver slices of sub-arctic fish species

open access: yesFrontiers in Marine Science
Due to the expanding oil-related activities, the arctic and sub-arctic marine environments are increasingly vulnerable to oil-related pollution such as accidental oil spills. These cold-water ecosystems harbor many fish species that are both ecologically

pH-Bildgebung am Gehirn von polaren Fischen: eine TauCEST Anwendung [PDF]

open access: yes, 2017
Chemical exchange saturation transfer (CEST) ist ein Bildkontrast, der die indirekte Detektion von Änderungen im pH ermöglicht. CEST bietet daher die Möglichkeit, die Säure-Basen-Regulation im Fischgehirn unter CO2-Konzentrationen, wie sie durch den ...

Sea ice algae as food source- High trophic dependency of important energy transmitters in the central Arctic Ocean [PDF]

open access: yes, 2017
Polar ecosystems thrive significantly on carbon synthesized by sea ice-associated microalgae during long periods of the year. Continued alterations of the sea ice system might not only have dramatic consequences for the sympagic (ice-associated ...

Energy budget, growth and exercise as proxies for performance capacity and fitness in Arctic fishes [PDF]

open access: yes, 2019
The boreal Atlantic cod (Gadus morhua) is entering the Arctic in response to rising water temperatures, likely increasing predation pressure on the endemic key species Polar cod (Boreogadus saida).
