Abstract: In order to make clear the relationship between salinity and the feeding, metabolic physiology of Crassostrea
ammonia excretion rate (NR) under different salinity (S) were studied at laboratory conditions using a running water system. The results
showed that, in the context of salinity 6~27, the salinity had a very significant effect on filtration rate and ingestion rate
