飞蛾是家鱼的好饲料,它含有丰富的蛋白质和一定量的脂肪、糖类、维生素等。鱼吞食飞蛾后生长迅速,增重快。怎样才能让鱼吃上飞蛾呢?飞蛾具有趋光性,可利用黑光灯诱集飞蛾喂鱼。黑光灯不能设置过低,以免鱼群争食时,池水溅到发热的灯管上引起爆裂。一般应置在距岸边2米远、高出水面1米左右的鱼池中。如果条件许可,置于鱼池中央效果更好。晚上黑光灯亮后,飞蛾和其他趋光昆虫纷纷飞来,碰灯落水,成为鱼的饲料。据观察,黑光灯周围20平方米内鱼群活跃,吞食声如同雨声沙沙作响。诱蛾喂鸡效果也很好。据试验,蛋鸡吃 Moth is a good feed for domestic fish, it is rich in protein and a certain amount of fat, sugar, vitamins and so on. Fish swallowed moths grow rapidly, weight gain fast. How to make fish eat moths? Moths have phototaxis, black light can be used to attract moths to feed the fish.

Generally should be placed 2 meters away from the shore, about 1 meter above the surface of the fish pond. If the conditions permit, placed in the central fish pond better.

It is observed that within 20 square meters of black light around the fish active, swallowing sounds like rattling. Moth feeding chicken effect is also very good. According to the experiment, the laying hens eat
