为了挖掘池塘生产潜力,提高池塘有效利用率,增加经济收入,我们选择县鱼种场东排1号,面积4.3亩,水深2.0～2.5米,防渗性强的建鲤精养池,进行网箱套养金鱼试验。该塘水源为黄河水,并配有30米深机井一眼,叶轮式增氧机一台。 经过1992年一年试验,结果在不影响建鲤生产的前提下,多产金鱼3560尾,其产值为4272元,扣除成本费1965元,实收2307元,即亩多盈利536.5元。试验表明,在精养池塘中利用网箱套养金鱼可以充分利用水中基础饲料生物。由于精养池投饲量大,鱼粪便排出较多,水质较肥,水生生物生长旺盛,为金鱼提供了充足的生物饲料。因此,套养金鱼发挥了池塘的
In order to tap the potential of pond production, improve the effective utilization of ponds and increase economic income, we choose County fish farm Dongbian No. 1, an area of 4.3 acres and a depth of 2.0 to 2.5 meters, impermeable Jian carp intensive pool, net Box set goldfish test. The pond water for the Yellow River water, and equipped with a 30-meter deep well, impeller aerator. After a year of testing in 1992, 3560 goldfishes were produced prolificly without affecting the production of Jian carp. The output value of the goldfish was 4272 yuan. After deducting the cost cost of 1965 yuan, it received a total of 2307 yuan, yielding a profit of 536.5 yuan. Experiments show that the use of cages in intensive ponds to raise goldfish can make full use of basic feed water organisms. Due to intensive feeding of intensive ponds, more fish excrement is excreted, water quality is more fat, and aquatic organisms grow vigorously, which provides sufficient biological feed for goldfish. Therefore, raising goldfish play a pond
