In order to disclose the distribution characteristics of shellfish of Sanmen Bay, field investigation was carried in four seasons, Jun 2002-May 2003, and 31 species of shellfish was identified in all samples collected by HNM sediment sampler. Mean annual biomass and mean annual density was 2.35 g m and 41 ind m respectively. High biomass and High density area was mostly inside the upper bay(4.28 gm、70 ind m), and lower biomass and density was in the other area. Biomass of different seasons is spring (3.55 g m)>summer(2.88 g m)>fall(2.18 gm)>winter(0.85 g m),

The physiological responses of Chlamys farreri and Argopecten irradians concentricus to environmental stressors, such as increasing temperature, decreasing salinity and starvation were studied in the laboratory. The oxygen consumption rate(OCR) and ammonia excretion rate (AER) were chosen as physiological indictors. The OCR of small sized scallops was higher than that of the

The scallop Clampys farreri is the main cultured species over the coastal farming areas in the northern China Sea. In the current decade, the growth rate of C. farreri sharply declined because of high culture density and exhaustion of food supply. Mass mortality of this species occurred in most of the farming areas in the northern China Sea, especially during summer and autumn since 1997. The

The large scale cultivations of the filter-feeding bivalves, such as scallop, oyster, mussel and so on, impact the sustainable development for itself and the environmental condition and ecological balance in the coastal bays and shallow seas in many countries, including China. Previous studies have shown that the macroalgae as a biofilter could take on the bioremediation function of the deteriorative

Five cDNA expression library of Pacific abalone Haliotis discus hannai Ino, HD-emb, HD-met, HD-JRh, HD-RwRh and HD-tri had been established. HD-emb was constructed from the embryos sampled at gastrula and early trochophore larva. HD-met was a library focused on the metamorphosis and established from the tissue mixture of several developmental stages from trochophore larva to juvenile 11 days post-spawning. HD-JRh was from a rapid growth family at
