由于饲料涨价,税费增加,市场疲软,池塘养鱼效益降低,影响着养鱼户的积极性。任县任城镇梁二脏、王建国等养鱼户30亩鱼池,1990年亩产达500—750公斤。纯收入10 00～15 00元,产量和效益均比其它养鱼户高2～3倍,他们的做法是:一、因地制宜养殖适销对路品种。这里人们普遍有爱吃鲤鱼的习惯,销售量较大。同时农副产品丰富,鱼饲料容易解决,因此他们确定以鲤鱼为主(占70～80%);为了净化水质搭配鲢、(鱼用)鱼20%;池堤种草放养适量草鱼。二、鱼种放养做到早、大、足。早放鱼种可以争取鱼类有效生长期,他们改春放为秋放,早放鱼种增加了生长期,而且秋后气温低,鱼体不易受伤,成活率高;早放使鱼种早适应、早开食、早生长,另外秋后鱼种比春天鱼种价格便宜。
As feed prices, taxes and fees increased, the market is weak, reduce the efficiency of fish ponds, affecting the enthusiasm of fish farmers. Any county towns Liang Liang dirty, Wang Jianguo and other fish farmers 30 acres of fish ponds, 1990 mu yield of 500-750 kg. The net income of 10 00 ~ 15 00 yuan, output and benefits are 2 to 3 times higher than other fish farmers, their approach is: First, measures to local conditions breeding marketable varieties. People here generally have the habit of eating carp, large sales. At the same time rich in agricultural and sideline products, fish feed easy to solve, so they identified mainly carp (accounting for 70 to 80%); in order to purify the water with silver carp, (fish) fish 20%; pool embankment grass stocking grass carp. Second, stocking do early, big, full. Early release of fish species can fight for the effective growth of fish, they put the spring to autumn release, early release of fish increased growth period, and the autumn temperature is low, the fish are not easy to injury, high survival rate; Adapt, eat early, grow early, another autumn fish species cheaper than spring.
