Scientific note Chlorophyll specific growth rate and grazing mortality rate of phytoplankton in the shelf water of the Bering Sea in summer
Abstract: Chlorophyll specific growth rate and grazing mortality rate due to microzooplankton were estimated based on the dilution methods, using surface waters collected at four stations in the continental shelf area of the Bering Sea in summer. Growth rates and grazing mortality rates of phytoplan...

Growth rates and grazing mortality rates of phytoplankton communities were ranged between 0. 0 6 d 1 and 0.56d and between 0. 0 4 d 1 to 0.33 d l, respectively. The high growth rate seems to have resulted from continuous supply of nutrients caused by gentle stratification, which is a favorable condition of the water column for phytoplankton growth. Growth and grazing mortality rates were almost the same at one station, where the most typical summer concentration of chlorophyll a was observed (less than l, u g l l) , suggesting that the major grazer seems to be micro-zooplankton in the Bering Sea shelf in summer.
