一防浅水 冬季雨水少,易造 成鱼塘水位降低。有些养鱼户喜欢将鱼塘水放浅,以为浅水能使鱼晒到太阳达到取暖的目的。其实冬天塘水浅,水温变化快,温差大,对鱼生长不利。水位下降后,鱼群密度相应增大,容易造成缺氧而使鱼停止生长甚至死亡。因此,冬季鱼池应保持正常水位。 A shallow anti-shallow water in winter less likely to cause reduced water levels in fish ponds. Some fish farmers prefer to dilute the fish pond water, that shallow water can make the fish sun to the sun to achieve the purpose of heating. In fact, shallow winter water, rapid changes in temperature, temperature, adverse growth of fish. After the water level drops, the fish density increases correspondingly, which will easily cause hypoxia and stop the growth and even death of the fish. Therefore, the winter pond should maintain normal water level.
