In hot fishing, what causes the fish not to open their mouths underwater?

1. It's hot and stuffy

Fishing in midsummer is the most common in hot weather. At this time, there will be no fish mouth when fishing. This is because the hot weather causes the water temperature to rise. This will also reduce the air pressure in the water and increase the oxygen content in the water.

At this time, the fish will lack oxygen in the water, so naturally they have no mood to eat. Sometimes it is found that fish floating on the water will absorb oxygen, which is also caused by this reason.

At this time, you can try floating fishing and catch fish floating from the bottom to half water. If there is no fish mouth, pay attention to changing the fishing position or taking the fishing rod home.

When fishing in hot weather, you can choose some cool waters, such as Qiaokou or shady places, where the water temperature is lower and the fish mouth will be better.

The weather is about to change.

In addition, when the weather is about to change, if there are some heavy rains or other bad weather in summer, the fish in the water will feel the change of air pressure in advance.

At this time, the fish will be uneasy in the water and will stop foraging. At this time, you can choose some foods with strong taste to stimulate fish to feed.

You can choose to add some fishy food or some bait to the bait, which can improve the fish mouth and increase the bait biting rate.

In addition, we should pay attention to the weather changes before fishing now. In summer, before it rains, the air pressure will decrease and the oxygen in the water will decrease. This time is not suitable for fishing.
