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,鱼病也多有发生。为使这一时期鱼类既能最大限度地生长增重,又避免因不利因素而受到损失,必须掌握以下诀窍,科学饲养管理。
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 phenomenon, fish disease also occurred. In order to maximize the growth and gain of fish during this period, and avoid the loss due to unfavorable factors, we must master the following know-how and scientific feeding and management.
