How about fishing at 3 to 5 degrees?

If it is cold, it is not suitable for fishing, because the body temperature of fish changes with the change of external environment. If the temperature is too low, the metabolism of fish will slow down, and if you eat less, you will naturally lose the bait.

However, I heard that fishermen are digging holes in the ice. Maybe the temperature of the water in the ice can be kept at a high level.
