Rearing Test of Ictalurus punctatus in Cold Plateau Zone

Three ponds with the areas of 800,1 000 and 1 000 m2 were settled in Yambajan aquaculture base for rearing test of Ictalurus punctatus in plateau zone.The results showed that as 30 000 fries were released,19 830 fingerlings of I. punctatus were obtained after 270 d rearing,with the average body length of 21. 2 cm,the average body weight of 216. 5 g,the survival rate of 66. 1%,and the fingerling harvest of 4 293. 2 kg. Thus,it is effective and feasible to rear I. punctatus with residual heat resources of power plants in cold plateau zone.
