Ocean and Polar Research, 2015 The contrast (fish body to medium ratio) of density and sound speed were measured to estimate acoustic scattering from small juvenile cod (Gadus macrocephalus) with the Kirchhoff-Ray Mode backscatter model. The density contrast was measured by the density-bottle method and the sound speed contrast was estimated by the time of flight method. The results

Авачинская треска Gadus morhua macrocephalus (материалы по биологии, систематике и промыслу)
Исследования водных биологических ресурсов Камчатки и северо-западной части Тихого океана, 2010 Biological data (about size, age, growth, body condition, migration) are obtained. The dominant role in the Pacific cod feeding is played by walleye pollock, Pacific herring, snow-crab and octopus. The hand rod and the long-line are reckoned the main fishing gear for Pacific cod in summer of 1935.
