一、网箱旁选钓位秋季,特别是仲秋之后,江河里的野生罗非鱼大部分都集中在渔民养鱼的网箱旁边。原因一是在所有的鱼类中,罗非鱼不耐低温。进入秋季,特别是仲秋以后,浅处水温比深处下降更快,而网箱都集中在3米以上的深水里,水温比较高,罗非鱼也就从浅水处转移到网箱底下及其附近居住。原因二是入秋后水草开始死亡,浅水处食物减少,而网箱则有不少饲料漏到底下供鱼虾吃,因 First, the cage alternative fishing next autumn, especially after mid-autumn, most of the wild tilapia in the river are concentrated in the fish cage next to fishermen. One reason is that tilapia are not resistant to low temperatures in all fish species. Into the autumn, especially after mid-autumn, the water temperature in shallow shallow decline faster than the depths, and cages are concentrated in deep water more than 3 meters, the water temperature is relatively high, tilapia also moved from the shallow water to the bottom of the cage and its Living nearby. The second reason is that plants begin to die after autumn and the food in shallow water decreases. However, there is a lot of feed leakage in the cages for fish and shrimp to eat
