Histological study of the ontogeny of the digestive tract in Oplegnathus fasciatus
摘要
Abstract
Under artificial culture conditions, the developments of the digestive system and its associated glands were examined histologically in Oplegnathus fasciatus from the first day until the 45th day post hatching (dph).The digestive tube of the first hatching larva was undifferentiated and straight. On the 1st dph, the rudimentary digestive lumen formed as the larve developed. On the second dph (TL, 2.61~2.98 mm), the intestine began to connected with the oesophagus. On the third dph (TL, 2.56~2.89 mm), the upper and lower jaw moved with the mouth and anus opening, indicated the first external feeding. At this time, the digestive tract, consisting of buccopharynx, oesophagus, stomach anlage, intestine and rectum, and the digestive glands, including liver and pancreas, being accompanied by the gas bladder anlage, formed. On the 4th dph (TL, 2.73~3.05 mm), the yolk sac was almost completely absorbed, with residual oil globule, and the acidophilic supranuclear vesicles were seen in the rectum. On the 22 dph, the the gastric gland began to differentiate and was not functional until the 45th dph.关键词
