一、控制水温水温的高低直接影响到黄鳝的生长与摄食。黄鳝是淡水鱼类中较为怕热的一种,其最适宜的生长温度为20℃~28℃。当水温高于28℃时,黄鳝摄食量明显下降,生长受到抑制。进入高温季节,由于鳝池水位较浅,水温很容易升至28℃,因此盛夏季节一定要做好防暑降温工作,主要方法有3种:
First, the control of water temperature The level of water temperature directly affects the growth and feeding eel. Eel is more afraid of freshwater fish in a kind of heat, the most appropriate growth temperature of 20 ℃ ~ 28 ℃. When the water temperature is higher than 28 ℃, eel consumption decreased significantly, growth was inhibited. Into the hot season, due to the water level shallow eel pond, the water temperature is very easy to rise to 28 ℃, so summer season must do a good job in summer cooling, there are 3 main methods:
