一、鱼鳖混养鱼鳖混养是一种双增双收、饵料互补的新模式。此法,可以充分利用水面与饵料,减少池底残饵淤积,以改善池塘水质及提高溶氧,有利于鳖与鱼类生长。鳖除吃掉一些体弱或病死鱼外,其粪便还可肥水,繁殖大量浮游生物,则为鲢、鳙鱼类提供美饵。另外,鳖的食物残渣,又能为鲤、鲫鱼等类提供美饵。试验证明,无论幼鳖池、成鳖池、亲鳖池都可放养鲢、鳙鱼和少量草、鲤、鲫及一些杂食性鱼类。一般每亩投放鱼种700～1000尾,其中鲢鱼占55%左右,鳙鱼占15%,草鱼占20%,
First, the fish and turtle polyculture fish and turtle polyculture is a double increase by double income, food complementary new model. This method can make full use of water and feed, reduce the deposition of bait at the bottom of the pond to improve pond water quality and improve dissolved oxygen, which is good for turtle and fish growth. In addition to eating soft-shelled turtle or diseased fish, the manure can be fat, breeding a large number of plankton, the silver carp, catfish provide bait. In addition, food residue turtle, but also for carp, crucian carp and other classes to provide the United States bait. Experiments show that, regardless of young turtle pool, as turtle pool, pro-turtle pool can stocking silver carp, catfish and a small amount of grass, carp, crucian carp and some omnivorous fish. Generally put per acre 700 ~ 1000 fish, of which silver carp accounted for about 55%, 15% of catfish, grass carp accounted for 20%
