Perna viridis (green mussel )is a warm-water bivalve mollusk with attributes of rapid growth, high production, great reproductive capacity, as excellent prospects for marine aquaculture. This paper presents the results of a study on the spawning period, larval ecology, settling period, semi-artificial spat collection and determination of optimum sea areas enviromental factors (temperature, salinty PH, transparency clarity and phytoplankton). The spawning season of green mussel in the Quanzhou area is in May to September, when seawater temperature is 23-26 C. Observations showed the spawning peaks from middle of May to June; settling stage starts from early and middle June to early July. Rubber rope and palm rope were selected as settling material as they gave better results.In addition, the time to lower the setting rope and the substrata required for the settling of spats are discussed.
