摘要
Larval digestive organs of Amur sturgeon,Acipenser schrenscki and hybrid sturgeon(Huso Huso♀×A.schrenscki♂) hatched out at 17～21℃ were successively observed under Olympus microscope after being sectioned. Histological development of yolksac, pharyngeal cavity, esophago, stomach, intestine, pyloric caecum, liver and pancreas is described. It shows that the development of the digestive organs of the two fishes is similar to several other Acipenseridae fishes. Characters of the digestive organs about the two fishes and the relationships among earlier development period, ingestion, digestion and absorption are discussed.
