1. Choose a small grass hole for fishing
A small grass hole refers to a grass hole with a diameter of about 20 cm at the mouth of the hole. Generally speaking, the water surface around small-diameter grass holes is covered with a large area of ??tight dry grass, which makes the water below have favorable conditions such as cold protection, heat preservation, light shading and concealment. It is a good place for fish to hide and overwinter. It is also a good fishing position for winter fishing.
2. Choose deep-water grass holes for fishing
Deep-water grass holes refer to grass holes with a water depth of about 2 meters. Fishermen all know that choosing moderately deep water for fishing is basic common sense for winter fishing. Because the water in this kind of grass hole is deep and the heat dissipation under the water body is slow, coupled with the influence of geothermal heat, the bottom water temperature is higher. Fish are very sensitive to water temperature. In such a good water environment, there are usually more fish hidden there.
