尼罗罗非鱼具有食性杂、生长快、海淡水均可养殖的特性。与对虾混荐更能提高经济效益。是适宜我国东南沿海和内陆地区养殖的优良品种。但是由于尼罗罗非鱼越冬需在摄氏14℃以上的水温条件下,因此在舟山各海岛上以往冬季要用电热增温方法解决罗非鱼亲鱼的越冬问题,成本很高。去冬,浙江省普陀县的水产养殖科技人员寻找到一个保护罗非鱼越冬的好办法。他们在附近海岛上利用一个近百米长、冬季天然水温能保持在摄氏14℃左右的废弃坑道,改造成
Nile tilapia with food miscellaneous, fast growth, sea and freshwater can be breeding characteristics. Mixed with shrimp and more to improve economic efficiency. Is suitable for China’s southeast coast and inland breeding of fine varieties. However, due to the overwintering of Nile tilapia at a water temperature above 14 ℃, it is very costly to solve the overwintering problem of tilapia broodstock in the past winter by using the electric heating method in all the islands of Zhoushan. Winter, Zhejiang Province, Putuo aquaculture scientific and technical personnel to find a good way to protect tilapia wintering. On the nearby islands, they used a nearly 100-meter-long wasted natural tunnel that maintained a natural water temperature of about 14 ° C in winter to transform into
