Abstract: Wild Erythroculter ilishaeformis fry in Minjiang river basin were taken as experimental material , which fed on artificial formula feed after feed domestication. After three years of net cage culture in reservoirs, the wild fish completely adapted to the living environment of net cage; the mean weight reaching 1.2kg, parent Erythroculter ilishaeformis with sexual maturity and reproductive capacity were attained. In 2005 and 2006 the selected parent Erythroculter ilishaeformis cultured by ourself were used for conducting experiments of artificial breeding in June after two months of intensive cultivation. The mixture of LRH-A2 and HCG was used as artificial injection oxytocin; by natural spawning, fertilization, hatching, and fry rearing, a total of 1602000 Erythroculter ilishaeformis fry were attained.
