The present paper reports the preliminary study on the reproductive behavior and embryonic development of clam mactra chinensis philippi based on the results of pond breeding. Along the coastal areas of Shandong Peninsula, the clam's spawning period starts in June and ends in August, and the peak is between late July and early August. The fresh meat weight ratio is increased with the

To clarify cuttlefish phylogeny, cytochrome c oxidase subunit I (COI) gene and partial 16S rRNA gene were sequenced for members of 7 Sepioid sepecies and several outgroups. Several phylogenetic trees were built by the neighbor-joining method. The coleoids were obviously be divided into two main lineages, Octopoda and Decapoda (Sepioiden + Teuthoidea). The order Sepioidea, including the

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
All-tripioids were produced by mating female diploids and male tetraploids in Pacific oyster,Crassostrea gigas Thunberg (referred to as DT groups), along with diploid controls using eggs from the same female diploids ...

All-tripioids were produced by mating female diploids and male tetraploids in Pacific oyster,Crassostrea gigas Thunberg (referred to as DT groups), along with diploid controls using eggs from the same female diploids (referred to as DD groups). Tetrapioid brood stocks were introduced from USA with the help of the 4C Company. Upon arrival at the experiment sites, tetraploid brood stocks

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
Two subgenera, Pseudiberus and Platypetasus under Pseudiberus, are merged into one genus,namely Pseudiberus, based on the fact that the snails cannot be distinguished based on shell characters. On studying the type sp...

Two subgenera, Pseudiberus and Platypetasus under Pseudiberus, are merged into one genus,namely Pseudiberus, based on the fact that the snails cannot be distinguished based on shell characters. On studying the type specimens housed in the Institute of Zoology, CAS, Platypetasus cixianensis is sunk as a synonym of Pseudiberus chentingensis. The possible causation for the differentiation of shells, between Cixian County population and Zhengding Population of the species,is discussed.
In preparation for family-based selective breeding, thirty-three families of the Pacific abalone Haliotis discus hannai Ino were produced between 2000 and 2002 using wild-type animals from Chinese (C) and Japanese (J)...

In preparation for family-based selective breeding, thirty-three families of the Pacific abalone Haliotis discus hannai Ino were produced between 2000 and 2002 using wild-type animals from Chinese (C) and Japanese (J) populations, or mutant red-shelled (R) individuals from a Chinese population.

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
