洛阳市河滩池塘养鱼万亩高产技术的研究

STUDIES ON THE HIGH YIELD TECHNIQUE OF FISH CULTURE IN 800 HA. AND MORE PONDS ON FLOOD PLAIN IN LUOYANG

将我国传统养鱼与现代技术相结合，创造了传统式、集约化和半集约化三种养殖方式共存、融合、变通和转换的格局。应用微机进行动态分析计算，８１２．６公顷河滩池塘，平均每公顷鱼产量提高到１００３５ｋｇ和２００８５元经济效益，分别比原来增加１０５．５％和７２．２％，总体效益十分显著。此外，还探讨了高产的理论问题。

The high yield technique for fish culture in 800 ha. and more ponds on flood plainwas studied in Luoyang City, Henan Province during 1991-1993. This technique is a new aquaculturemodel in which the conventional, moderate intensive and intensive methods coexist, merge, traditionalmethods and modem technology. Not only is this technique suited to the local aquaculture conditionand market requirement, but it promotes the proess of the appliaction of proportionate feedstuff andmechanization of aquaculture. Therefore, this technique makes the aquaculture management containingthe traditional practices and new technological contents as well. It has raised the productivity andeconomic efficiency dramatically. The dynamic analysis results by computer showed that the averageproductivity and economic efficiency of the 821. 6 bect ponds in the flood plain were 10 035kg/ha and20 085 Yuan/ha respectively, the increase were 105. 5% and 70. 2% respectively. The comprehensiveeffciency is striking. In addition, this paper also studies theories of this technique.
