In summer, the weather is gloomy and depressing, and the fish are floating up and down, so there is no way to change the bottom of the fish. Do fish float up and down without eating at this time?

There are many reasons why fish float from the bottom of the water. One of the most special reasons is that the oxygen content in the water is greatly reduced, and the fish feel anoxic, thus floating up from the bottom. The distribution of oxygen in water has such a rule that the shallower the water layer, the higher the oxygen content, which means that the oxygen content near the water surface is the highest, and the oxygen content gradually decreases with the increase of water depth.

In addition to being able to float off the bottom in the absence of oxygen, some fish floating off the bottom may also float off the bottom in search of food. For example, when fishing, because bait and nest materials are constantly thrown into the water, some fish actively foraging will not wait for the arrival of ingredients at the bottom of the water, but will float from the bottom to a shallower water layer to compete for ingredients.

However, this does not mean that all fish will do this. Some fish with weak appetite or poor physique will still feed under the water. In other words, it is only part of the condition that fish feed on the bottom. Therefore, it can be imagined that if you give up fishing and drift instead, the conclusion is that only the fish that drift off the bottom will be caught, and the fish that do not drift off the bottom will not be caught.

Therefore, when the fish only partially floats off the bottom, the most effective fishing method is not to fish at the bottom, but the fishing trip, that is, to slow down the sinking speed of the hook bait by increasing the fishing height and reducing the specific gravity of the bait. If the fish floating off the bottom go for food, you don't have to wait for the bait to sink to the bottom, so lift the rod immediately. If no fish are looking for food when the bait sinks, you can catch these fish that are looking for food under the water after the bait sinks to the bottom.

Fishing is generally not recommended in this weather, but some fishermen seldom fish once and a half a week, so they will bite their teeth even if they know that the temperature is bad. On this premise, if you read the weather forecast in advance and know that the fishing day is not good weather, you must choose your fishing position carefully. If you don't watch the weather forecast, or when you come out in the morning, the weather is fine, but the back has changed, and you feel that you are sweating less, but your body is sticky and your inhalation is not so smooth, then you should think that the air pressure has affected the fish mouth, so don't be afraid to change places in case of danger.

The amount of dissolved oxygen in water is closely related to air pressure, but it does not mean that it is only 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 situation will be stronger. 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.
