First, the fishing spot must be quiet. Grass carp likes to flock, swim half-water, look for food, and are timid. If they are a little alert, they will run away immediately. Therefore, no matter where the angler chooses to fish, he must keep the neighborhood relatively quiet. Throw the pole lightly, make small moves, try not to talk or shout. Second, the method of feeding the nest to catch large grass carp has a particularly good effect. Using distiller's grains (about 5 kg) as bait can also quickly attract grass carp into the nest and quickly bite the hook. To grasp the time, arrive at 7 am 10, 0 pm to 3 pm, and 5 pm to 6 pm. And the time to take the bait should be fast rather than slow, that is, fishing begins twenty or thirty minutes after throwing the bait. Because the biggest feature of grass carp is that it comes and goes quickly. If it takes a little time, most fish will go to the nest. Third, we must grasp the timing of lifting the pole. Grass carp generally have a regular pattern of foraging and biting hooks, which is characterized by shaking up and down a few times, suddenly falling down, and then pulling the buoy into the water or on the top to make the buoy cross the water. The bigger the grass carp, the more stable and slower the buoy moves. Therefore, anglers should seize the opportunity to lift the pole in time, so that nine times out of ten there will be no empty hook. Fourth, don't be impatient when walking the fish. After the grass carp bites the hook, it is really hard to say that it gives the angler the kind of pleasure and enjoyment because of its large size, fierce pulling force, bent pole and tight line. However, because grass carp is big, the pulling force is fierce and slightly improper, it is easy to break the rod and run away, leaving regret for anglers. Grass carp bites the hook and then walks, which becomes the key to whether it can catch water fish or not. If you are impatient and eager for success, there will often be decoupling and disconnection. Once you find that the fish has bitten the hook, you should hold your horses and take your time. Don't pull the fish out of the water in a hurry, let alone pull it ashore. Raise the fishing rod, keep a certain angle, and let the fish swim slowly under the water. Then walk the fish in time and conveniently. After several rounds, when the fish's strength is exhausted and its stomach turns white, it is pulled to the shore and fished ashore with a net. Don't pull the rope or lift the fish by hand. In the process of walking fish, once a tug-of-war occurs between fish and people, the fishing rod in your hand should be lowered, pulled aside and the direction of the fish head changed before walking. Five, to be equipped with a hook and line for grass carp fishing. Hooks should be large, the thread should be thick, and the hooks should generally be no less than No.7-No.8, and the knotting method of one thread and two hooks should be adopted. Connect the secondary line with a length of 20 cm to the main line, and its length is 10 ~ 15 cm. The main line is generally not less than 2.5, and the branch line is not less than 2.0.
