Abstract: Living environment of shell (including distribution, substrates,salinity and range of temperature, etc), feeding habits. diseases, growth charae-ters, and the harvest period are all presented in this paper in order to providesome information available for exploitation and conservation of this shell. 1. The shell mainly distributes all over the Pacific coast and often occurs inthe region from intertidal zone to subtidal zone at the depth of 30m or so. 2. Its best growth season is from May to August, and its suitable salinity forsurvival ranges from 11.2% to 28.8%. 3. In laboratory experiment, the upper lethal temperature of the mussel is 36℃ and when they are cultured below the temperature of-3℃ to-5℃,they willdie within three days. 4. During April to October, when the water temperature becomes warmer, the mussels are usually infected by a fluke (Follodistomum sp.). The infection so-metimes reaches to 30-40%. 5. The Musculus senhousei mainly lives on benthic diatoms. 6. The growth of shell length is proportional to the growth of body weight asthe equation of regression W_t=0.000149L^(2.7764), and its relative constant (r) is 0.9963.
