摘要
近年来,科学工作者为充分发挥土地最佳经济效益,正在致力于把各种养殖业与种植业进行综合培植,并获得较好的试验效果。为探索发挥池塘水体的生产力,自1987年开始我们以革胡子鲶(Clarias leather)、凤眼莲(Eichhornia crassipes)、福寿螺(Ampullarum crossean)为试验材料。连续两年进行了鲶、草、螺人工生态群落的效益研究。
The advantages of this community can be summarized as: (1) superior in ccological stability. (2) growing well of catfish, water hyacinth and snail and (3) higher economic benefit than that of traditional fish culture in pond. The proper stocking size and density of catfish and snail and the proper cultivation and utilization of water hyacinth in the integrated community are discussed in the paper.
