不同养殖方式的鱼池生态经济效益分析

ECOLOGICAL AND ECONOMICAL ANALYSIS AMONG DIFFERENT FISHERY PONDS

分析了不同养殖方式鱼池的生态经济效益，结果表明：（１）进行不同养殖方式的畜禽联合养殖的鱼池，其生态经济价均高于对照池；（２）水产养殖要增产增收，不仅要提高物质和能量的利用率，而且与整个鱼池投入的科学性、合理性及投入的总水平有关。从作者所做的Ｂ号实验池结果来看，只有把两个方面很好地结合起来，才能获得比较全面的经济效益。

The ecological and economical benefits among different fishery ponds are analyzed.The ecological and economical values in ponds of comprehensive fish culture raising duck and fish or raising pig and fish is higher than the values in the contrast pond raising fish only. In ordes to increase economical benefits,it not only needs to increase conversion rates of food and energy but also needs to consider the level of total investment. The experimental results of B pond ( raising duck and fish ) supported the idea.
