盛夏季节,一些精养鱼池很容易发生鱼病流行和“泛塘”事故。而鱼池“泛塘”往往要比暴发鱼病造成的损失大得多。轻者使鱼几天不摄食,体质下降,生长停滞,仿佛得了一场大病;重者可使鱼“全军覆没”。要防止“泛塘”的发生,必须采取综合措施,防患于未然。其措施主要有: 1.对多年的精养鱼池,要在冬季干池后,清除过多的淤泥 清除淤泥可防止池底腐殖质积累过多,细菌大量繁殖,消耗水中大量溶解氧。 2.坚持定时、定位、定量投饵 饲喂以少吃多餐为原则,以鱼1～2小时内能吃完为宜。不要时多时少,时有时无,造成鱼暴食或饥饿。每隔3—5天
In summer season, some intensive fish ponds are prone to fish epidemics and Pan Tong accidents. The pond “Pan Tong” is often much larger than the loss caused by outbreaks. The light of the fish a few days without food, physical decline, growth stagnation, as if got a serious illness; severe can make the fish “annihilated.” To prevent the “Pan Tong” from happening, we must take comprehensive measures to take preventive measures. The main measures are: 1. For many years of intensive fish ponds, in the winter dry pool, remove excess sludge to remove sludge can prevent the accumulation of bottom sediment humus, bacteria multiply, consuming a lot of dissolved oxygen in water. 2. Persist in timing, positioning, quantitative feeding to feed less eat the principle of eating fish within 1 to 2 hours is appropriate. When not more than a few hours, sometimes no fish, resulting in fish gluttony or hunger. Every 3-5 days
