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℃, the appetite will decrease and the action will be slow. If the water temperature drops below 15℃, it will die.

Warm-water fish are most suitable for living in 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 than10 C, 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 optimum 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. When a thunderstorm occurs during or before the pre-match preparation, the host country should send a command signal to postpone or interrupt the pre-match preparation. It is forbidden for athletes to enter or stay in the competition area, and it is forbidden to assemble fishing gear. If weather conditions permit, the competition can be continued within the limited competition schedule, or the competition time can be shortened to the shortest effective competition time of 48 hours.

When there is a thunderstorm during the competition, the host country should send a signal to stop the competition immediately, and the athletes should quickly go to the shelter. When the weather conditions improve, the first signal will be sent to let the athletes return to the competition position; After five minutes, a second signal will be sent to allow the game to continue. The game must last at least 48 hours to be effective.
