1. Use fishing net: catch a large net to the bottom of the pond and lift it in a short time to catch all the small fish at the bottom.
2. Use bait: throw some foods that small fish often eat into the pond, wait for the small fish to be attracted to eat, and then use the net to catch them.
3. Grabbing plants: There are often some underwater root plants or underwater aquatic plants in the pond. You can put a net bag or container around them, and catch them with a net bag when the small fish often go to activities.
4. Use hand fishing: Fishing requires a microscope or a magnifying glass. Aim the lens at the small fish in the water and catch it slowly. It should be noted that fishing requires observing and mastering certain aquatic biological skills.
These are several ways to catch small fish. Generally speaking, attention should be paid to protecting aquatic organisms and maintaining the ecological environment when catching small fish. At the same time, we should act in accordance with local laws and regulations to avoid violating relevant laws and regulations.
