革胡子鲶俗称埃及塘虱,系暖水性高效养殖鱼类.由于长期的自然选择,使其适应于较高水温中生长、栖息、耐低温能力较差.我国大部分地区不能在池塘里自然越冬,但通过采取各种因地制宜的人工增温措施,使水温保持在15℃左右,越冬成活率可达90%以上.这里介绍三种增温越冬方法:1.塑膜覆盖越冬法 选用背风向阳、水深1.5～2米的池塘搭棚覆盖塑料薄膜,池塘过大要将鱼集中到小范围后再进行搭棚盖膜.温度低的地区可盖双层塑膜.这种方法各个地区均可采用.
Because of long-term natural selection, it adapt to the growth of higher water temperature, habitat, low temperature tolerance is poor.China most of our country can not win the pond in the natural winter , But by taking a variety of measures according to local conditions of artificial warming, so that the water temperature maintained at about 15 ℃, overwintering survival rate of up to 90%. Here are three methods of warming the winter: 1. plastic film overwintering method selection leeward, Water depth of 1.5 to 2 meters of pond scaffolding covered plastic film, the pond is too large to focus on the fish to a small scaffolding cover film. Low temperatures can be covered double plastic film .This method can be used in all regions .
