Abstract: In this study, cultivation facilities and techniques for fingerlings of Chinese Sturgeon (Acipencer sinesis) in workshop were introduced. Initiation of feed, domestication of formulated feed of young fish, water temperature, water quality and disease control techniques are the key factors affecting the survival rate and growth of the young Chinese Sturgeon. The optimal water temperature for fingerlings rearing should be between 18℃ and 22℃. The feed conversion rate of formulated turtle-feed was 0.45 while that of sturgeon-feed was 0.67. Under our experimental condition, Chinese sturgeon grew at 17.88mm/day in body length and 16.8mg/day in body weight. 70 days after hatch, SGR of 1-18days post-hatch was 8.34% day-1 and that of 18-72days post-hatch was 6.93% day-1, fingerlings with 10-15cm in lengrh were produced in our workshop and were ready to be released into the natural habitats of Chinese Sturgeon. Further study should be carried out to identify the pathogen. From 2000 to 2003, 200,000 fingerlings (10-15cm in body length) of Chinese Sturgeon have been cultivated in Propagation and Re-stocking Experiment Base for Chinese Sturgeon in Yangtze River Fisheries Research Institute. Survival rate of Chinese Sturgeon is up to 90%.
