The specific depth varies with fish, water and season. For example, you can catch 2 ~ 3 meters of big fish in a small river, and it is generally recommended to catch more than 3 meters in a reservoir, because big fish are highly vigilant and rarely go to shallow waters except for some special circumstances. As the saying goes, "fishing big fish in deep water" is the truth.

Fishing big fish in reservoirs can be done with hand poles such as platform fishing poles, traditional poles, throwing poles such as sea poles, rock poles and forepoles. The fishing line is made of 3.0 or more nylon thread, the fishing hook is made of thick hooks such as Yi Shi hook, New Kanto hook and Qianyou hook, and the fish float can be made of vertical float or seven-star float. The specific line, hook and drift depend on fishing method, fish situation, water situation, season and other factors.

We should choose the right time to catch big fish in the reservoir. From the seasonal point of view, fishing can be done almost all day in spring and autumn with suitable climate. When the temperature is high in summer, you should choose relatively cool morning, evening and evening fishing, and when the temperature is low in winter, you should choose sunny noon fishing. The above data are from Zhihu.

The benefits of fishing:

1 First of all, you must stare at the float for a long time when fishing. Compared with staring at computers and mobile phones all the time, fishing not only won't hurt your eyesight, on the contrary, it will protect your eyesight to some extent. Our eyes will be used better and better, and we will see more clearly. And all of you who play mobile phones and computers are doing chronic damage to your eyes.

2. Secondly, fishermen are generally healthy and often contact with nature. They can not only breathe fresh air, but also let the body inhale a lot of negative oxygen ions, which is of great benefit to the body's metabolism. The famous Changshou Village in China has produced a large number of centenarians because of its abundant negative oxygen ions.

The third point is that you can exercise your thinking ability. Fishing is not as simple as putting the hook in the water. If you want to catch good fish, you must consider various factors, including temperature, weather, bait and so on. Even what habits fish have should be kept in mind. And after the fish is hooked, it is necessary to judge immediately.
