Orange-spotted grouper is a benthic protogynous marine fish with sex inversion. It is one of the most important culturing fish in the southeast of Asia. As in other vertebrates, its growth is mainly controlled by growth hormone . Few data are available concerning the regulation of GH in grouper. In this paper, the regulation of growth hormone release from pituitary of orange-spotted grouper and its mRNA level was determined by radioimmunoassay and RNase protection assay.
