- Abstract
In this study, the facilities and techniques of fingerling production for the Chinese Sturgeon (Acipencer sinesis) cultivation as practiced in the hatchery of the Yangtze River Fisheries Research Institute are described. Initiation of feeding in larvae, adaptation of young fish to formulated feeds, water temperature control, and maintaining other water quality parameters within limits as well as disease control techniques were the key factors affecting the survival rate and growth performance of young Chinese Sturgeons. The suitable range of water temperatures for fingerling rearing is considered to be between 18 and 22. The feed conversion rate when using formulated turtle-feed at 70 days post-hatch was 0.45 while that of specific sturgeon-feed was 0.67. Under our experimental conditions, SGR (Specific Growth Rate) of the young Chinese sturgeon was 8.15% day-1, 7.71% day-1 and 6.96% day-1 in the years 2000, 2001 and 2003, respectively. Fingerlings of 10-15 cm total length were produced in our facilities and were at that time ready for release into the natural Chinese Sturgeon habitats. Disease control still is a major problem requiring more intensive research.
