Fish predation of snow crab Chionoecetes opilio and shrimp Sclerocrangon salebrosa in Peter the Great Bay (Sea of Japan) during summer period
The size of seasonal consumption of snow crab Chionoecetes opilio and shrimp Sclerocrangon salebrosa by fishes in Peter the Great Bay is significantly higher than the estimations of abundance of these species calculated by survey data was shown. The degree of underestimating of crustaceans increases with decreasing size. The possibility of correction of hydrobionts stocks values obtained by direct surveys was discussed.
