三、鱼的泳层问题由于气压低,导致水底含氧量不足,鱼层上移,因水位上升,淹没的杂草烂,导致水底酸碱度高、氨氮含量高、PH值改变,水底水质不适应鱼类活动觅食,致鱼离底。出现这些情况,就不能守着水底不放,若钓离底、半水或浅水处,则会比较好的收获。 Third, the problem of fish swim because of low pressure, resulting in the lack of oxygen at the bottom, the fish moved up, due to rising water levels, submerged weeds rotten, leading to the bottom of the high pH, ​​high ammonia content, PH value change, bottom water does not adapt to the water quality Foraging for fish activities, resulting in fish from the end. Occurrence of these conditions, we can not keep the bottom of the water, if fishing from the bottom, half water or shallow water, it will be better harvest.
