The amount of carbons in the metabolic pool for protein synthesis and the amount of carbons in the pool consumed for the metabolism other than protein synthesis were calculated to be 7.56μg/0.5 g-gill and 3.94μg/h/0.5 g-gill, respectively. The amount of carbons in the pool for RNA synthesis and the amount of carbons in the pool consumed for the metabolism other than RNA synthesis were calculated to be 9.85×10-1μg/g-gill and 1.32×10-2μg/h/g-gill, respectively. By in vivo study, half life times were found to be 5.8 days for gill-protein, 3.96 days for midgut-protein, 2, 6 days for gill-RNA and 10.6 days for midgut-RNA. In the case of gill, the proteins about mucus glands inside of a ciliated groove were very active metabolically.
