鱼类多品种混养是立体利用水体,合理 利用各种饵料,充分发挥池塘潜力而获得 高产的一项重要措施。混养是根据各种鱼 类的栖息习性、生活习性、食性等不同特 点,合理确定。从鱼类的习性看,相对地 可分上层鱼、中层鱼、底层鱼三类。即鲢、 鳙为上层鱼、草、鲂为中层鱼,鲤、鲫为 底层鱼。因此,将这些鱼混养在同一池塘 中,就可以有效地利用池塘的各个水层,与
Multi-species fish polyculture is the three-dimensional use of water, the rational use of various feed, pond full potential to obtain high yield an important measure. Polyculture is based on various habitats of fish habitat, food habits and other different characteristics, reasonable to determine. From the habit of fish, relatively divided into upper fish, middle fish, the bottom three types of fish. That is, silver carp, 鳙 for the upper fish, grass, 鲂 for the middle fish, carp, crucian carp as the bottom of the fish. Therefore, by mixing these fish in the same pond, each pond of water can be effectively used, and
