| 摘要 | Histological development of the digestive tract and specific activities of three digestive enzymes (trypsin, alkaline phosphatase, and pepsin) were studied in rock bream Oplegnathus fasciatus from hatching to 50 days after hatching (DAH). At hatching, the digestive tract appeared as an undifferentiated straight tube and differentiated into the buccopharynx, esophagus, stomach, intestine, and rectum at mouth opening by 3 DAH. The taste bud and mandibular teeth were present in the buccopharyx at 8 DAH. The goblet cells appeared in the esophagus at 8 DAH and in the buccopharyx at 9 DAH. The stomach anlage was formed at 2 DAH and developed into cardia, fundus, and pylorus at 14 DAH. The gastric glands were visible at 16 DAH, and the pepsin was firstly detected on 22 DAH. At 2 DAH, the intestinal valve appeared and divided the intestine into anterior intestine (AI) and posterior intestine (PI). The rectum was differentiated from the PI at 3 DAH. The supranuclear vacuoles were visible in the rectum by 6 DAH, and the lipid inclusions were present in the AI at 8 DAH. The alkaline phosphatase was detected at 1 DAH, and the increase in its activity indicated the maturation of the intestine after 40 DAH. The hepatocytes and pancreatic cells were differentiated from the blast cells at 2 DAH, and the acidophilic zymogen granules in the exocrine pancreas were observed simultaneously. The trypsin was detected by 1 DAH and increased to the maximum at 19 DAH, followed by a decrease as the stomach became functional. |
