6～9月气温高,水体中的浮游生物大量繁殖,为各种鱼类生长创造了良好条件。加之鱼类活动迅速,摄食力强、新陈代谢度高,因此生长最旺盛、育肥最快。但此期鱼类特别容易发生缺氧、浮头甚至泛塘现象。鱼病也随之产生。为使在这一黄金时期中,鱼类既能最大限度地生长增重,又不因不利因素而受到损失,可掌握以下诀窍进行饲养管理。一、强化投饵饵料以青料为主,精料为辅。青料如浮萍、苏丹草、黑麦草、水花生等;精料如玉米粉、麦麸、枯饼、蚕蛹、螺蚬、糟渣等。每天投喂量:精料按每100公斤吃食鱼投喂4～5公斤;青料按每100公斤草
From June to September, the temperature is high, and the plankton in the water body multiply, creating favorable conditions for the growth of various kinds of fish. Coupled with rapid fish activity, strong feeding, high metabolism, so the most vigorous growth, fattening the fastest. However, this period of fish is particularly prone to hypoxia, floating head and even Pan Tong phenomenon. Fish diseases also occur. In order to maximize the growth and weight gain of fish during this golden age, and without any loss due to unfavorable factors, the following know-how can be used for feeding and management. First, to strengthen bait bait material mainly green, fine material supplemented. Green material such as duckweed, sudangrass, ryegrass, peanut, etc .; fine materials such as corn flour, wheat bran, dry cake, silkworm pupa, snail, bad slag. Feeding amount per day: fine materials fed per 100 kg feeding fish 4 to 5 kg; green material per 100 kg of grass
