Abstract:The experiment was carried out under laboratory conditions to study the effects of temperature and body weight on feeding rate of scallop Patinopecten yessoensis. The feeding rate of the scallop of 5 levels of dry tissue weight was determined at temperatures of 5, 10, 15, 20 and 25 ℃. The results showed that the feeding rate of P. yessoensis was affected significantly by temperature and body weight (P<0.05). The relationship between feeding rate and temperature or dry tissue weight can be described as FR=b0＋b1T＋b2T2＋b3T3 and Y=aXb. The assimilation efficiency of P. yessoensis was affected significantly by temperature (P<0.01), but not significantly by dry tissue weight (P>0.05). The maximum feeding rate of P. yessoensis occured at 15 ℃, and the maximum assimilation efficiency was found at 10 ℃.
