摘要
采用提早繁殖、池塘强化育种、网箱强化养殖等综合技术，将当年建鲤苗种养成平均尾重６５８．９ｇ。试验网箱２．４亩，平均每亩净产６８４７０．１ｋｇ，成活率９４％，饵料系数１．２６，每亩利税２５．９７万元，投入产出比１：２．１３。专家鉴定认为，本研究成果达国内同类研究的先进水平，其中平均尾重、商品率、饵料系数居国内同类研究的领先水平。
The fingerlingr of Jian-carp were fsrmed up to the adult fish with comprehensive techniques such as moving up the breeding time,strengthening to rear fingerlings in ponds and intensifying cultivation in net cages. The average weight of the adult Jian-carp was 658. 9g per individual. The toeal area of the experimental cages was 2.4 mu and the average poy mu net yield was 68470. 1kg. The surviral rate was 9%,the feed coefficient 1.26. The profit and tax per mu were259.7 thousand yuan. The ratio of input and output was 1:2.13. The result,appraised by experts,has met the dvanced standard,compared with that of the same study project.
