Is it appropriate to fish silver carp and bighead carp during the day on a hot day of 40 degrees?

It is not suitable to catch silver carp and bighead carp during the day in 40 degrees high temperature weather. Because when the temperature is high, fish will find a shady place to hide, such as running under the shelter, which brings great difficulties to fishing silver carp and bighead carp.

In addition, people who fish at high temperatures are prone to heatstroke. So fishing at 40 degrees is not recommended. If you really want to fish, you can choose to fish in the morning and evening when the weather is cool, which is also the time when fish are active.

Fishing water temperature

Fish is a temperature-changing animal, and its body temperature will change with the change of water temperature. Therefore, their growth and reproduction need suitable water temperature environment. According to the different water temperatures suitable for normal growth and reproduction of fish, it can be divided into three types: warm water, warm water and cold water.

Warm-water fish generally have the strongest appetite and the fastest growth and reproduction speed when the water temperature is 30℃-50℃. When the water temperature drops below 20℃, it will lead to loss of appetite and slow action; If the water temperature drops below 15℃, it will die.

Warm-water fish are most suitable for living at the water temperature of 15℃-30℃; When the water temperature is above 30℃, avoid cold water (usually deep water); Water temperature above 40℃ will cause large-scale death of warm-water fish; When the water temperature is lower than 10℃, the fish will lose their appetite and stop growing. When the water temperature drops below 4℃, most of them will stop eating and hibernate. Therefore, the optimal water temperature for catching warm-water fish should be between 15℃-30℃.

Cold-water fish will swim to the cold water area above 20℃; The water temperature of 4℃- 15℃ is the most suitable temperature for them, and cold-water fish is also the most suitable for fishing at this time.
