在故县水库90个规格为12m×4m×4m的网箱中进行鲟鱼成鱼网箱规模化养殖试验,取得成功。5月中旬投放鲟鱼种,平均规格125g/尾,投放密度41/m2,养殖全程投喂人工配合饲料,10月中旬至12月份完成生产、销售。试验共生产鲟鱼成鱼15.56万尾,105.8吨,平均产量245kg/m2,平均规格0.68kg/尾,成活率88.4%;共投喂饲料166吨,饲料系数1.98,平均利润154.7/m2元,投入产出比为1.29:1。
In 90 counties in Guxian Reservoir 12m × 4m × 4m cage for sturgeon fish cage large-scale farming trials, and achieved success. In mid-May sturgeon species, the average size of 125g / tail, put the density of 41 / m2, feeding the whole breeding artificial feed, from mid-October to December to complete production and sales. The experiment produced a total of 155,600 sturgeon adult fish with an average yield of 245kg / m2 and an average yield of 0.68kg / tail, with a survival rate of 88.4%. A total of 166 tons of feed were fed, with a feed coefficient of 1.98 and an average profit of 154.7 yuan / Input-output ratio of 1.29: 1.
