Patinopecten yessoensis is good-sized mariculture scallop in the world. Its' economic value is highest among all the scallops. It was explanted to Changhai county of Dalian from Japan in 1982. After popularized culture in the north areas of China, good economical benefits were obtained. Patinopecten yessoensis belongs to coldish shellfish. In 2003, in order to increase its' cultural scales

Scallop aquaculture in China has beeh growing rapidly in the past decades and there is a big scallop culture industry which plays an important role in the economic development of the coastal provinces in China. Chlamys farreri and Argopecten irradians are the important cultured scallop species which are cultured widely in the northern coastal provinces. Recently, scallop culture in China is experiencing from a mortality problem, and suffering from a great economic loss.

Filtration rate is one of very important physiological index of filter feeding bivalves. Nowadays, there are two kind of method on measuring it: direct and indirect methods. Flow-through chamber method is one of traditional indirect method that filtration rate is obtained by time the concentration of food and the clearance rate. Biodeposits method belong to direct method which calculated

Seawater velocity was measured with gypsum blocks in scallop culture areas in sanggou bay and the results were compared with data collected by auto-logged current meter model SD6000. Simultaneously, the factors affecting dissolution of gypsum blocks were studied and the standard curves relating weight loss of gypsum blocks and volume, temperature, salinity, time and water speed
