Live bait earthworm and red worm are better for crucian carp fishing in winter. Earthworms should be those that are not too thick, rosy in color and smooth in appearance, and turn over with a touch. The red worm should be a male worm, with big head and black skin, and squeezed by hand. Female crucian carp, thin and soft, doesn't like to eat. When fishing with live earthworms, use barbed hooks to avoid falling off underwater because of earthworms' struggle. If the fish you catch is small, you can use a thinner earthworm, or divide the earthworm into several sections and put it on the hook; To catch bigger fish, you can go through the whole earthworm from the middle. Fishing with earthworms can also change. For example, put a bottle of water beside you and a can of dry powder bait that can lure fish. After the earthworm is hung, it is repeatedly soaked in water and dry powder to make it as big as a marble like Yuanxiao, and then thrown into the fishing spot. In this way, after the powdery bait is atomized at the bottom of the water, a concentrated nest will be formed around the earthworm, which will produce miraculous effects. When fishing for red worms, it is necessary to bundle red worms into small bundles in advance, with three or four or seven or eight in each bundle, depending on the size of the fish. Don't pierce the red worm when you put the bait, but tie it tightly. In some waters, it is better to fish with red worms, with spiny hooks and single worms. The tip of the hook should penetrate from the middle of the mouth of the red worm to the tail of the worm, taking the bleeding of the red worm as the standard. Once pierced, it is necessary to change insects and start over, changing bait for each fish. In order to better stimulate the appetite of fish. You can also chop up some earthworms or red worms before going out that day and put them in a bottle with meat and soup. Be careful not to mix earthworms with red worms. When making a nest, mix it with food and throw it into the fishing point, which will make the fish bite quickly and for a long time. In addition, fishing enthusiasts should pay special attention: when using insect bait to fish, be careful. When your finger is injured and bleeding, it is best not to let the wound come into contact with red worms, so as not to catch vascular parasitic red worms. If you don't pay attention to hand hygiene when fishing and eat earthworm eggs by mistake, you will also get an intestinal parasitic earthworm disease similar to ascariasis. These two conditions have appeared many times at home and abroad, especially the red worm disease is extremely difficult to cure. Fishing in winter embodies the tenacious character of fishermen who never give up and pursue a better life. Undoubtedly, it is the best way to temper your will, but you should also conform to the laws of nature, avoid going out early and returning late, be hungry and thirsty, and pay attention to warmth and safety.
