福建省连城县是闽西北地区养鱼大县,2004年养鱼产量7619t,其中草鱼占总产70%,达5400t。近年来,随着饲养水平的不断提高,养殖方式有较大的改进,县城郊各村一部分池塘养殖形式改为一年二茬,即春放秋收、秋放春收;一部分池塘则一次放养多次捕大留小,即轮捕轮放。经过4个月-6个月的养殖,草鱼规格达到1kg以上即捕捞上市,而后需补放数量不等的大规格鱼种,因此,草鱼秋片大规格鱼种在当地供求矛盾十分明显。为解决这一问题,结合几年来小范围网箱草鱼生产经验,2004年进行水库较大规模网箱培育草鱼秋片鱼种生产,取得较好的收益。
Liancheng County of Fujian Province is a big fish farming county in the northwestern part of Fujian Province. In 2004, the production of fish was 7619 tons, of which grass carp accounted for 70% of the total, reaching 5400 tons. In recent years, with the continuous raising of breeding level, breeding methods have been greatly improved. Some of the ponds in the suburbs of villages in the suburbs have been changed into two crops in a year, that is, Sub-catch big stay small, that is, round catch round. After 4 months to 6 months of farming, grass carp specifications reached 1kg or more fishing market, and then need to be replenished a large number of different sizes of fish species, therefore, large grass carp fish large size of the contradiction between supply and demand in the local is obvious. To solve this problem, combined with years of small-scale cage grass carp production experience, in 2004 the larger cage cage culture grass carp autumn fish production, and achieved better returns.
