Biology of Calanus glacialis in the Far-Eastern Seas
Features of biology of Calanus glacialis are described and its somatic production is estimated on the base of data collected in 29 complex surveys conducted by TINRO-Center in the Okhotsk and Bering Seas in 1986-2006. The value of specific daily production was 0.0049 in the Okhotsk Sea and 0.0060 in the Bering Sea. The highest production in the Okhotsk Sea was observed on its northern shelf and at western Kamchatka, in Bering Sea the shelves of the Karaginsky and Olyutorsky Bays as well as the southeastern and eastern parts of the Anadyr Bay were recognized as the most productive areas for this species. Its total harvest in the summer-autumn period is estimated as 24.58 mln t in the Okhotsk Sea and 11.55 mln t in Bering Sea.
