投放药饵的时间和疗效的关系极大。有养鱼经验的渔民知道,在各地各种鱼塘中,吃食性鱼类在一日中,开始摄食的时间不尽相同。这是因为池塘的地理、生态环境的差异所致。如水温较高,溶氧量充足,鱼的代谢作用旺盛,索食时间就早些;水温较低,溶氧量较少,有缺氧浮头现象,鱼的索食时间就晚些。因此,投喂药饵治疗鱼病时,应根据该塘鱼进食场的具体时间,适时投入(一般应是进食前 The timing of drug delivery and the effect of a great relationship.

Such as higher water temperature, adequate dissolved oxygen, the strong metabolism of fish, feeding time earlier; lower water temperature, less dissolved oxygen, floating hypoxic phenomenon, the fish’s feeding time later. Therefore, feeding bait treatment of fish disease, should be based on the specific time of the pond fish eating place, timely investment (should generally be before eating
