This paper focused on the effects of temperatures, light intensity, algal cell densities on grazing rates of Perna viridis on Alexandrium tamarense, and grazing pressure of Perna viridis on other microalgae under laboratory conditions, comparison of the effects of different algal cell densities of A .

Effect of tempreature,body weight,food density on filter feeding rate and assimilation efficiency of Corbicula fluminea;

Using laboratory ecological methods, the filter feeding rate and assimilation efficiency of Chlamys farreri were studied at static experiment from April to June 1999.

The filtration rate, oxygen consumption rate and ammonia excretion rate of Mercenaria mercenaria were measured at 11.

From July 2000 to August 2001, at the seawater Research and Development Centre, a research was made on the filter feeding and its growth of the juveniles Coelomactra antiquata.
