How to catch reservoir crabs?

Generally, cages are placed in the middle and shallow water areas with lush aquatic plants, and pig liver or other internal organs are used as bait, because the taste of internal organs is stronger than that of ordinary meat, which can attract crabs in large waters. Since crabs are nocturnal, they should be released from their cages every night and collected the next morning. You can also go fishing with a net in the stream next to the reservoir after ten o'clock every night. When you shine a strong flashlight on the crab's eyes, it will reflect light, which is obvious at night. When you shoot it, the crab will be slow, disoriented and easy to be caught.
