1, change the bait formula. Xiaoyu is very interested in seasonings such as fried bean powder, fried sesame powder and sesame oil. When they smell the fragrance, they will shuttle around the bait. If they find that there are many small fish in the water, they should change the formula in the bait, throw the bait that big fish like, add less of the above spices and increase the concentration of wine.

2. Abandon shallow water and catch deep water. Fishing proverb says: "catch big fish in deep water and small fish in shallow water." This means that big fish usually live in deep water. So, you can find a deep water area nearby to rebuild your nest. Small fish are afraid of big fish and rarely set foot in deep water, so there is less interference from small fish in deep water.

3. Fishing outside the nest. If you find a lot of small fish in the nest, you can try to throw bait at the periphery of the nest, that is, hook the bait in water 50 ~ 80 cm away from the nest. The density of small fish here is low, and big fish are wandering around, so you can catch crucian carp and bream that don't want to compete with small fish for food.

4. Open a small fish trap. It is found that there are many small fish in the nest, so another nest with more fragrant powder can be planted in the windward 1 ~ 2 meters of the original nest, so that the small fish will go with the fragrance, which can greatly reduce the density of small fish in the main nest and reduce the interference of small fish.
