Black sea bream Acanthopagrus schlegeli having 42mm in body length as seed for release project were compared with the same size of wild fish. Hatchery-produced fish had shorter intertinal length and higher lipid reserves in muscle, hepatopancreas, and intraperitoneal fat body compared with wild fish. Lipogenic enzyme activities of liver, glucose-6-phosphate dehydrogenase (EC 1.1.1.49) and 6-phosphogluconate dehydrogenase (EC 1.1.1.44) showed a tendency to be higher in hatchery-produced fish. The different intestinal length and lipid metabolism which were caused during rearing conditions would be associated to seed quality for the release project.
