一些水产养殖户对鱼鸭混养有不同的认识,有的认为鱼鸭混养可促进鱼鸭双丰收;有的则认为,鱼鸭混养会影响鱼的产量。其实,鱼鸭混养好不好,关键是得法不得法。那么,如何进行鱼鸭混养才算得法呢? 1.放养鱼种要适当。在鱼鸭混养的池塘里,应以养殖罗非鱼为主,其次为滤食性鲢鱼、鳙鱼和杂食性鲤鱼、鲫鱼等。而草鱼,因喜爱清静的水体,故应不放或少放。
Some aquaculturists have different understanding of fish and poultry polyculture. Some people think that fish and ducks polyculture can promote the double harvest of fish and ducks, while others think that fish and ducks polyculture will affect fish production. In fact, fish and ducks polyculture is not good, the key is not law. So, how to fish and duck polyculture be considered law? 1. Fish stocking should be appropriate. In fish and ducks polyculture ponds should be dominated by tilapia, followed by filter-feeding silver carp, mackerel and omnivorous carp, crucian carp and so on. The grass carp, because of the love of quiet water, it should not be put or less.
