Wrap the fish after the net is spread, because fish are gregarious animals and have gregarious characteristics, so when the net is closed, no fish will escape from the bottom of the net alone, waiting for everyone to run in panic. Will eventually be captured.
There is also a lead pendant hanging beside the fishing net. After the net was opened, it quickly sank to the bottom of the water. When it is pulled up, the speed slows down and the pendant will gradually approach the bottom of the water. Then slowly lift it up. The fish caught in the net will not fall because of the pendant.
In natural rivers, it is not illegal to fish with nets without violating the local regulations on the fishing season. If someone contracts the corresponding waters of the river, they can't fish in it, which involves infringing on other people's property. It is illegal to use fried fish, poisonous fish and electric fish to destroy fishery resources for fishing.
