In summer, the temperature is high, the air pressure is relatively low, and there is little dissolved oxygen at the bottom of the water area. What if there is no fish mouth?

Summer is the off-season for fishing, and the main reason why it is difficult to catch fish is the climate. High temperature and low pressure weather in summer can easily lead to hypoxia in water. Fish lacking oxygen in water can't be eaten well, but it's normal not to catch fish.

The amount of dissolved oxygen in fishing point water is closely related to air pressure, but it does not mean that it is related to air pressure. Whether it is still water or running water, whether it is windy or not, and whether it is cool or not has a certain relationship. Remember, the oxygen drive characteristics of fish in summer are very obvious. If the dissolved oxygen is slightly higher than other parts, there may be more fish and the opening situation will be better. The first thing is to find a fishing spot in living water, especially the slow flow or even trickle in still water will attract fish to this place. For example, around the upstream water inlet, it is a very good choice because of the rich dissolved oxygen brought by running water. There are also some rivers and reservoirs with sluices, and there may be a trickle around the sluices, which is also a good area for fishing in summer.

Adjust the fishing position. Hot weather will reduce dissolved oxygen in water. If O2 is not enough, will fish have the idea of eating bait? For example, it is usually sultry before a thunderstorm. The key hazard of high temperature refers to the bottom water temperature, and the dissolved oxygen ratio in the middle and upper layers has little change. Therefore, fish originally in the middle and upper layers will have a good appetite for food, such as silver carp, yellow catfish and pomfret. People often see groups of fish floating on the water. At this time, you can try fishing. Even if you throw the bait into its mouth, it won't eat it. The sultry weather will cause the fish's mouth to be blocked. At this time, it is not only that you can't catch fish, but most of the fishing friends present have bad mouths.

So we can also infer that if everyone has no mouth and stays away from the fishing conditions in the past, the first doubt is the temperature. In fact, everyone can feel it, such as sticky and uncomfortable breathing. In this case, you can consider changing the fishing position first, and then you can move to a cool area with strong dissolved oxygen, such as a drain and a downdraft. In this area, only when fish are more comfortable can we consider eating, and we can achieve great success in fishing. However, grass fishing is not random. Because of the water temperature and light in summer, it is especially suitable for the growth of aquatic plants. But once it grows too vigorously, it will lead to the decrease of dissolved oxygen in water quality and increase the oxygen uptake of fish.
