How big is the air pressure for fishing crucian carp in winter?

The optimum air pressure for crucian carp fishing in winter is between 990- 1005 hectopascals.

Air pressure is one of the most important meteorological indicators for fishing, because air pressure will affect dissolved oxygen in water. Judging from the air pressure value, the best air pressure for fishing in early winter is 990 ~ 1005 hectopascals. From the point of view of air pressure change, we should choose the weather where the air pressure rises suddenly or continuously. When the air pressure value is low and the air pressure suddenly drops or shows a downward trend, the fish are not enthusiastic about eating or even don't open their mouths to eat bait.

Temperature is one of the important weather indicators that affect fishing, but different species have different temperatures suitable for fishing. For example, crucian carp can be fished as long as the water temperature is between 2℃ and 29℃, and carp can be fished as long as the water temperature is not lower than 5℃ and not higher than 30℃.

Wind direction is one of the important weather indicators that affect fishing. The best wind direction for fishing in winter is southeast wind and south wind, and the worst is northwest wind. When the wind force is less than level 3, it is recommended to grab the tuyere, and when the wind force is greater than level 3, it is recommended to grab the tuyere.

Early winter: the temperature in early winter is often not too low. At this time, it is recommended to go fishing in hot and sunny weather, but the weather with large temperature difference between day and night or before and after is not suitable for fishing, because the temperature difference will affect the enthusiasm of fish.

Midwinter: Midwinter is the season with the lowest temperature all year round. It is recommended to go fishing at noon, the temperature is relatively high. The first fishing spot is the aquatic plant area, followed by the water inlet, Huishuiwan, Huajian and Hekou. The water depth of the fishing point is preferably 3 ~ 4 meters.
