三中全会前,我场成鱼水面500亩,平均亩产成鱼只有40余斤。产量低的主产原因是:投放鱼种规格太小(3寸长),粗放粗养,水体生产条件差。自1979年以来,我场列人县商品鱼基地,先后共挖精养鱼池903亩。1983年600亩成鱼池平均每亩投放均重3两的大规格鱼种1033尾,其中均重4.3两的草鱼种297尾,占29.6％。这一年平均亩产成鱼1201斤,除去亩放种301斤外,净产成鱼900斤。1984年和1985年亩净产成鱼千斤以上,其中草鱼占50％(表1),大大提高了成鱼商品价值。 Third Plenary Session, my field into a fish 500 acres, an average of only 40 acres of fish into fish. The main reason for the low yield is that the size of the fish put on is too small (3-inch long), crude and extensive, poor water production conditions. Since 1979, I have been listed as a commodity fish base in the county and successively dug 903 mu of fish ponds. In 1983, a total of 1033 large-size species of fish weighing 3 and 2, respectively, were put into an average depth of 600 mu of adult fish ponds, of which 297 were grass carp species weighing 4.3 and accounting for 29.6% of the total. This year an average of 1201 kilograms of fish into adults, except for mu stocking 301 pounds, the net income of 900 pounds of fish. In 1984 and 1985, the net production of mu was over 1000 kg, of which grass carp accounted for 50% (Table 1), greatly increasing the value of adult fish products.
