一、控制水温 黄鳝比较怕热,其最适水温为22℃—28℃。当水温高于28℃时,其摄食量明显下降,生长受到抑制。进入夏季,鳝池水位较浅,水温容易升至28℃,因此,盛夏一定要做好鳝池的防暑降温工作。 (1)种植水生植物。既可遮挡部分阳光,便于黄鳝的潜伏,又可改善池塘环境,降低水温,有利于黄鳝生长。但水生植物的遮盖面积不得超过总面积
First, the water temperature control eel more afraid of heat, the optimum temperature of 22 ℃ -28 ℃. When the water temperature is higher than 28 ℃, its food intake decreased significantly, growth was inhibited. Into the summer, eel pond water level is shallow, the water temperature easily rose to 28 ℃, therefore, summer must be good eel pool summer cooling work. (1) planting aquatic plants. Can block part of the sun, easy to eel potential, but also improve the pond environment, reduce water temperature, is conducive to the growth of eel. However, the cover area of aquatic plants shall not exceed the total area
