池塘和稻田养殖尼罗罗非鱼(以下简称尼鱼)经济效益显著,尤其在大面积推广稻田养鱼的地区,尼鱼作为食用鱼主养对象,深受养殖者的欢迎,所以有些地方的群众把尼鱼称作“稻田鱼”。但是,由于尼鱼不耐低温,成了大面积推广的主要障碍。为了摸索一条简单易行的越冬保种方法,我们利用本区丰富的低温泉水(常年水温16～20℃)资源,在1983年初试成功的基础上,1984年进行了生产性试验,分别采用塑料大棚覆盖式和敞开式两种方法进行尼鱼越冬试验,以寻求就地越冬保种、就地繁殖苗种、就地饲养的途
Pond and rice farmed Nile tilapia (hereinafter referred to as the nauplii) significant economic benefits, especially in large areas to promote rice culture in the area, the nauplii as the main object of food fish, welcomed by farmers, so in some places The masses call the fish “paddy fish.” However, due to the low temperature resistance of the nauplii, it has become a major obstacle to large-scale promotion. In order to explore a simple and easy method of overwintering conservation, we use the abundant low-temperature spring water (annual temperature of 16 ~ 20 ℃) resources in this area. Based on the successful initial test in 1983, we conducted productive tests in 1984, Plastic greenhouses covered and open two ways for the Nigeria fish overwintering test, in order to seek local overwintering conservation, in situ breeding seedlings, on-site feeding of the way
