Fishing is a way for many people to relax in their leisure time, so how deep should they go to catch bighead carp? In fact, it is possible to control the water level of bighead carp at about three to fifteen meters. The water layer where bighead carp is located is not fixed. The depth of fishing today is different from tomorrow, and the depth of fishing during the day and at night is also different. When the temperature is too high, they will also go to the water layer with relatively low temperature to enjoy the cool. When the temperature is low, they will subconsciously keep warm in the deep water, so the water level for bighead carp fishing is more flexible. Fishing spots should be located in downwind or windward, avoiding headwind, and choosing places where algae exist on the water surface, such as leeward or return air bay, as well as the junction between the lapping surface and calm water surface, deep water on steep banks, etc.
