摘　　要：2005年4月初至年底进行了白斑狗鱼池塘主养试验,共选放体长5 cm的优质鱼苗5000尾,并搭配适量鲢鱼苗。成活率达90%,平均质量550 g/尾,最大个体1.4 kg,平均产量达9375 kg/hm2,投入产出比为1∶2.64,饵料系数约5,取得了良好的经济效益。From early April 2005 to the end of the year, a pike Northern pike （Esox lucins L. ） culture experiment was carried out in a aquafarm nearby the Tai-hu Lake. About 5000 individuals of Northern pike fingerlings were stocked and reared in a 0.27 hm^2 pond. At the end of the experiment, the mean body weight was 550 g including the maximal above 1.4 kg and the survival rate reached 90%. The averge yield reached 9375 kg/hm^2, the output value reached about 712 500 yuan/hm^2. The ratio of investment to income was 1 ： 2.64 and the food conversion rate was about 5.
