The Pacific oyster (Crassostrea gigas), as the most productive cultured shellfish in the world, has considerable economic importance and value. Yet research on its sex determination remains lacking. Here, a novel HMG-box-containing homolog of the sox gene was uncovered in C. gigas (named ...

In order to explore the changes of nutrients in the fertilized eggs of Australian freshwater lobster during development, the fertilized eggs in the egg-nauplius stage, the embryo with eye pigment forming stage, the prepare-hatchling stage and newly hatched shrimp were systematically analyzed in...

A 12-point checklist in the design and practical application of active surveillance of diseases in aquatic organisms (farmed and wild) has been developed to serve as a methodological approach and guidance for a multidisciplinary team particularly in countries where surveillance expertise is...

The Pacific oyster (Crassostrea gigas) has been widely cultured as a commercially important bivalve. Intercrossing of inbred strains is regarded as an efficient method to increase yield (heterosis), so the development of inbred lines is common in the breeding strategies of C. gigas. However,...

Triploid oysters with their large size and consistent meat quality have become a major component of the oyster aquaculture industry worldwide. It has been observed that triploid Pacific oysters (Crassostrea gigas) showed high levels of variation and sex-specific differences in sterility. Here, we...

Pacific oyster (Crassostrea gigas) is one of the most widely cultivated shellfish species in the world. Because of its economic value and complex life cycle involving drastic changes from a free-swimming larva to a sessile juvenile, C. gigas has been used as a model for developmental,...

Slow growth and genomic instability are the main problems facing tetraploid oyster breeding. In response to the above problem, we developed tetraploid by using Crassostrea gigas 'Haida No.3', a new variety with rapid growth and black shell color, and analyzed the growth, survival and ploidy of...

Long-lasting high temperature and bacterial exposure are two critical environmental factors contributing to the mass mortality of oysters in summer. In this study, we investigated the effects of high-temperature exposure and Vibrioalginolyticus infection on the mortality of the Pacific oysters, ...

The Pacific oyster is one of the most economically important species in global aquaculture . However, the production of C. gigas has been compromised by widespread and severe summer mortality events in recent years. To explore the possibility of obtaining a new hybrid line with rapid growth and...

In order to investigate the effect of pupa peptide powder and maggot powder on the growth performance, body composition and digestive enzyme activities of juvenile mud crab (Scylla pseudoaculea), the basic diet was supplemented with 10% pupa peptide powder and maggot powder to feed the juvenile mud ...
