春季水温不稳定,藻类生长相对缓慢,养殖动物开始摄食。因价格及规格因素,部分鱼塘年底不会清塘卖鱼,这些鱼塘就要面临春季管理问题。春季要综合做好水质管理,方能保证养殖顺利进行。1.调节水位春季气温变化较大,不少地区会经历由零下到零上的转变过程,若水位较浅,则容易造成水温变化过快,引起鱼的“感冒”或者冻伤,导致死
Spring water temperature is unstable, algae growth is relatively slow, farming animals began feeding. Due to the price and specification factors, some ponds will not be cleared for sale by the end of the year. These ponds will face spring management problems. Spring to do a good job of water quality management, in order to ensure the smooth progress of farming. 1. Regulation of water temperature changes in spring large, many areas will experience from zero to zero on the process of change, if the water level is shallow, it is likely to cause rapid changes in water temperature, causing fish “cold” or frostbite, leading to death
