Establishment of reliable pedigree information different lineages is crucial for selective breeding and stock enhancement programs. However, owing to the absence a assay parentage assignment, such lacking in orange-spotted grouper (Epinephelus coioides), which an economically important coral-reef fish. In this study, we developed two multiplex microsatellite polymerase chain reaction systems th...

Growth hormone-releasing hormone (GHRH) and the receptor, GHRHR, constitute important components of the hypothalamus-pituitary growth axis and act on the downstream growth hormone (GH). PACAP-related peptide/pituitary adenylate cyclase activating polypeptide (PRP-PACAP) is a paralog of GHRH. These genes all play key roles in development and growth patterns. To improve the quality of cultured fi...

To study the influence of mariculture on mercury (Hg) speciation and distribution in sediments and cultured fish around Hong Kong and adjacent mainland China waters, sediment samples were collected from six mariculture sites and the corresponding reference sites, 200-300 m away from the mariculture sites. Mariculture activities increased total mercury, organic matter, carbon, nitrogen and sulfu...
