In this study, razor clams (Sinonovacula constricta) seeding was conducted in rotifer cultivation devices, by ordinary process of seed breeding for bivalve and Chlorella sp. alga as live food. It was shown that the clams usually spawned in the evening and stopped spawning in the early morning....

Eriocheir sinensis is one of the most widely commercially cultured crabs which is generally cultured in the ponds mainly fed with formula feed, frozen fish and mixture with formula feed and frozen fish. However, high-density pond culture and feeding frozen fish with unstable source and imbalanced...

Environmentally friendly polycultures have been adopted largely by culturing pearl mussels in hanging-cage systems together with fishes in ponds. The pearl mussel has been one of the most important species in freshwater multitrophic level cultivation systems and have been widely applied in...

Pearls are known as "the queen of gems". The improvement of the cultured pearls quality is the focus of pearl industry and the important topic in the research field of pearls. In this paper we summarized the standard of evaluating the quality of cultured pearls in six aspects, including color,...

Breeding programs in oriental river prawn populations would benefit from a knowledge of heritabilities for growth-related traits to assess their potential for genetic improvement. This study reports the results of heritability estimation and evaluation of epistatic interactions for growth-related...

A 2 804 bp full-length cDNA sequence of catalase (CAT) gene from Hyriopsis cumingii was obtained by rapid amplification of cDNA ends. It consists of a 112 bp 5′ UTR (untranslated region), a 1 388 bp ORF (open reading frame) and a 1 303 bp 3′UTR, and the deduced protein is composed of 462 amino...

The Chinese mitten crab (Eriocheir sinensis) is among the most important species in China and other countries, and it contributes significantly to aquaculture and meeting protein demands for the fast-growing human population. To ensure their sustainable exploitation, management, and use in ...

The razor clam, Sinonovacula constricta, is a commercially important bivalve. To date, there have been very limited quantitative genetic studies of this species, especially in different aquaculture environments. This study is the first report of genotype by environment (G × E) interactions for...

Hyriopsis cumingii is the most economically important aquaculture species for freshwater pearl production in China. Previously, no single nucleotide polymorphisms (SNPs) markers were developed from expressed sequence tags (ESTs) in this mussel. In this study, we report the characterization of 56...

Estimating of narrow-sense heritability is often the initial step in an applied animal selective breeding program. To summarize the proportion of variance due to genetics, a total of 26 families of razor clam Sinonovacula constricta were used to estimate the heritability of growth traits under high ...
