1. Making bait: Put fermented dough or rice bran into water, let it ferment in water, make bait, and add a proper amount of turtle food, which will attract turtles to come to feed.

2. Prepare the catching device: you can prepare a small cage or plastic bag and put it around the bait. When the water turtle is lured near the bait, it can be caught in a small net cage or directly by hand.

3, hand grasping method: If the number of water turtles is small, you can directly grasp it in the water by hand. Where the current is not too big and you can see the bottom of the water clearly, you can grab it directly with your hands.

4. Trap lamp method: Using trap lamp at night is also a common method. You can put a lamp next to the bait, and the light will attract water turtle insects, and then catch them with cages or hands.
