Two wild stocks of Mandarin fish(Siniperca chuatsi) derived from Poyang Lake and Gaoyou Lake, were bred by way of reducing the temperature and light intensity in concrete ponds, as well as using cages in earth ponds. The results showed that the proportion of mature, postmature and abortion of the female bred in concrete ponds were 36.7%, 40.0% and 23.3% in Poyang Lake stock, and 40%, 43.3% and 16.7% in Gaoyou Lake stock, respectively, while the male sperm motility was normal. The female bred in cages of the pond were all postmature or abortion, while 46.7% of the male testis were degraded completely. The inducing trials were carried out in each six female of mature group and postmature group. Inducing rate, egg of the unit weight, fertilization rate, hatching rate and emergence rate of mature group were significantly higher than those in postmature group. The test reached 1 187 000 of larvae, 963 000 of fry 1.3 cm of size and 681 000 of fingerlings 3 cm-5 cm of size. The experimental results showed that the breeding season can be postponed to the end of July by reducing the temperature and light intensity, achieved batch of fry nursing during high temperature period, and laid the foundation for off-season farming in Mandarin fish.
