During metamorphosis and settlement the digestive system of Japanese flounder (Paralichthys olivaceus) exhibits various morphological features that include: differentiation and development of gastric glands and pyloric caeca coupled with partial degradation of the pancreas; involution of the liver; inflation of the gall bladder; and shortening of gut epithelium height. Pepsin-like enzyme activity increases markedly as metamorphosis proceeds, while trypsin-like enzyme and amylase activities drop significantly. High percentage of newly settled wild flounder at the climax phase of metamorphosis have empty stomachs, indicating that feeding ceases while the gut is undergoing reorganization. These findings suggest that the morphological and functional changes of the digestive system that occur during metamorphosis of Japanese flounder relate to the drastic diet shift at settlement from zooplanktonic to benthic prey. |
