Some aspects of the plankton communities functioning in the western Bering Sea
On the basis of plankton surveys conducted in the western Bering Sea in 2010–2015, production characteristics of zooplankton were calculated and analyzed. Zooplankton was divided into two trophic groups: predatory (mainly chaetognaths and Hyperiids) and non-predatory (Copepods and Euphausiids) zooplankton. The highest non-predatory zooplankton production was in 2002–2007 (2706 mg/m3) in the northern areas of the Sea. Production of predatory zooplankton was the most significant (937 mg/m3) in the waters of northern areas in 2007–2011. In general, in the western part of the Bering Sea during the autumn P/B-ratio of non-predatory zooplankton was from 2.8 to 3.6, and the prey — 1.74 to 2.2.
