我场有苗种培育池180亩,亲鱼培育池30亩(兼套养鱼种)。为了养出大鱼种,促进商品鱼生产的发展,我们针对本省鱼苗生产晚,培育期短的特点,从1967年开始全面采取一养到底的饲育方法。几年来,通过不断的实践、认识,培育技术有所提高。一般每年都生产出秋片鱼种150-170万尾,出池鱼种有70-80%达到3寸以上,其中鲢、鳙鱼约半数达到3.5寸以上。苗种池平均每亩育成鱼种7,000-9,000尾,全期培育成活率50%左右。 My field has a nursery breeding pool of 180 acres, 30 acres of broodstock breeding pool (and sets of fish species). In order to raise large fish species and promote the development of commercial fish production, we aim at the characteristics of late production and short cultivation period of fry production in our province. From 1967 onwards, we took a full-scale rearing method. Over the past few years, through continuous practice, awareness, cultivation techniques have improved. Generally, 150-170 million of autumnal fish species are produced each year, and 70-80% of the species of the ponds reach more than 3 inches, of which about half of silver carp and bighead carp reach more than 3.5 inches. The seedling ponds average 7,000-9,000 fish per acre breeding, breeding throughout the period of about 50% survival rate.
