Effects of temperature, salinity, and food availability on shell growth rates of the Yesso scallop.

ABSTRACT: Shell growth rates in relationship to seasonal changes of environmental factors were studied in a wild population of the Yesso scallop Mizuhopecten yessoensis inhabiting Amur Bay (Peter the Great Bay, Sea of Japan, Russia). It was found that food availability is not a limiting factor for the scallop growth in the study area. A phytoplankton biomass of 3.5-6.0 g m^-3 provided high scallop growth rates. The largest daily shell increments were observed with a phytoplankton biomass of about 6 g m^-3. With a decrease in the phytoplankton biomass to <2 g m^-3, as well as with an increase to >11 g m^-3, the daily shell increments reduced. It appeared that the main exogenous factors causing the seasonal variations in the scallop growth rates are the w
