Abstract: Chinese sturgeon (Acipenser sinensis) is an adromous fish. In order to protect species, artificial reproduction of it has been caught out, and by now the intensive reproduction has been achieved. Intensive reproduction system for Chinese sturgeon fry is composed of primary and assistant system. The former includes four breeding ponds of different sizes with a total area of 2902.3 m2, fertilization and hatch equipment. The later consists of transportation vehicle for parent fish, system of providing and disposing water, offering oxygen, maintaining and raising temperature, offering feed, and so on. This system needs little investment, has good harmonization and is convenient to operate. Fish ponds are made of different construction materials and techniques with different shapes to meet ecological demands for larvae and fingerlings at different development stages. The water temperature and the pattern of infall and discharge can be adjusted conveniently with automatic draining contamination, which provides the culture ponds with different flow patterns, good and stable water environment. The system can induce more than 16 parent fish to spawn in single one season, hatch 1.664×106 fertilized eggs and culture 2.355×106 larvae of 1～15 days old and 0.4233×106 fingerlings with 10～15 cm in total length, which can achieve the complete process of reproducing Chinese sturgeon. The system is the same with intensive reproduction and larger scale breeding of fingerling for other fishes.
