What is the best air pressure for fishing?

The optimal air pressure for fishing is between 990-1005 hPa, which means higher air pressure is better for fishing. Generally, before the arrival of cold air, windy days and typhoons, the air pressure is relatively high, which is more suitable for fishing. In low-pressure weather, fish openings are not good and it is not suitable for fishing.

Because the increase in air pressure will allow sufficient dissolved oxygen in the water, it is generally a good weather for fishing. At this time, the fish are very active and actively forage for food. If you master the timing of fishing well, you will naturally catch many fish. Other high weather often occurs in autumn, or autumn is often a season of cool and refreshing air. At this time, dissolved oxygen is high and fish are active. In addition, there is a need to supplement food for the winter, so autumn is the first golden season for fishing.

Fishing precautions:

1. Fishing in autumn should be vegetarian, and fishing in deep shade should be done when the temperature is high during the day. In late autumn, the weather turns cooler or even colder, and fish flock to deep water ditches and depressions to find food. In terms of fishing method, you can use muddy bait to fish deep, and the nest material will have a fishy and strong smell.

2. When fishing for wild carp in the wild, use grain-flavored fish with a natural fragrance, and add some bean cakes, cornmeal, sweet potatoes and other grains appropriately. Big carp prefer bait with a lot of aromatic cereal ingredients, while small carp prefer fishy-fragrant bait.

3. Where there is grass and fish. Places with aquatic plants can reduce strong sunlight exposure, which is in line with fish's habit of avoiding strong light and tending to weak light. In addition, aquatic plants in autumn are not as dense as in summer, so even if fish hide among them, they will not feel lack of oxygen. In autumn, there is a large temperature difference between morning and evening, and water leather can also protect fish from wind and cold.

4. Under normal circumstances, when fishing in waters where the density of large fish on the water is thin, the number of nests must be large. Because there are more baits, the target will be bigger and the duration will be longer, so that scattered fish can be lured into the nest.
