【摘要】 1993、1994两年试验证明：猪、草、鱼养殖模式具有节省饲料、肥料，低耗高效等优点。试验表明，用此模式，每百公斤猪粪可产草128.8kg，喂草鱼可产草鱼5kg，带动滤食鱼3.5kg，比用猪粪直接养鱼增产240％。试验表明：主养草鱼，适当搭养其他品种才能取得高效益。搭配比例为：草鱼45～50％，鲢、鳙30～35％，鲤15％，鲫、鲂5％。更多还原

【Abstract】 The two-year continuous experiment showed that the fish-grass-pig fish farming model cost low and profited high. The fish yield was only2. 5kg when used 100kg pig manure directly to rear fish. However, in this experiment, using the same amount of pig manure, 128. 8kg grass can be harvested then 5kg grass carp and 3. 5kg filter-feeding fish can be obtained, made the total yield 8. 5kg, so we concluded that, in the fish-grass-pig model polyculture,choosing grass carp as the major species,the filter-feeding and omnivorous fish as the minor species, resonably stocking,can make high output.更多还原
