How to fish from 3 degrees to 14 degrees

14-degree fishing skills are: the change of temperature; Changes in air pressure; The change of relative humidity and the influence of temperature change. Fish is a temperature-changing animal. When the environmental temperature changes, it is necessary to adjust its body temperature to adapt to the environmental temperature change. The influence of air pressure change. The level of air pressure has an effect on the fish. The air pressure is high, the solubility of oxygen in water is relatively large, and the fish is active. More importantly, the influence of the fluctuation of air pressure. The air pressure drops sharply, the fish situation is extremely poor, and it may even float without moving.
