What weather is suitable for fishing red-tailed fish?

The weather with a temperature of more than 20 degrees, high air pressure, moderate light and moderate wind is most suitable for catching the red tail.

1, the temperature exceeds 20 degrees.

The red tail has the highest temperature requirement. They like to be cool, so don't fish when it is too hot.

2. The air pressure is very high

Pressure is related to the oxygen concentration in water. The higher the air pressure, the more oxygen, and the red tail is active. Generally speaking, people will choose to fish when the sky is crisp, that is, when the air pressure is relatively high, to ensure that the oxygen concentration in the waters is relatively high and the red tail is more active.

3. Moderate mild to moderate wind.

Summer needs special attention. If the light is too strong, you need to avoid it and fish in a cool place. Finally, the wind, moderate wind can bring some oxygen to the water, and fishing can be done when the wind is moderate. Pay special attention to the light in summer to avoid too strong light. Finally, considering the wind, moderate wind can bring oxygen to the water and make the red tail more active.
