In summer, the air pressure is generally low during the day, and the night fishing effect is very good. Moreover, fish are more active at night. If the bait is well matched, it is easy to catch fish. Carp are very picky about food and generally don't eat bait that doesn't suit their appetite. Granular bait is the favorite of carp and crucian carp, and the taste of gathering fish is very important. The bait is half of yellow flour or raw pond particles. Then it is suggested that any 3-4 kinds of aging bait can catch Sparus macrocephalus, and it is necessary to choose a good fishing position for night fishing. If the air pressure is low, choose shallow water level, then choose deep water level, and then make a nest to gather fish. Now the black hole is not for bait, but the bait can be well matched. It is very important to gather fish with flavor and stimulate the mouth. Generally, it is better to add additives and small drugs to increase the fish gathering effect, and the water and fertilizer penetration is better. There are many fishermen here. In recent two years, several combined small medicine bags produced by superior products were added to bait and nest materials to gather fish with special flavor. The main reason is that there is an advantage when releasing fish and grabbing fish. Sometimes, both sides can shut up. Black hole fishing is first of all very important, followed by the state and taste of bait, and then the fishing skills. Good luck. I hope the answer will help you a little. I hope it can be adopted.
