CATDOLL : CATDOLL: Are there any crab species that can reproduce on their own in freshwater lakes?

River crabs are OK. But they don't taste as good as hairy crabs. But it is best to breed them in flowing water, with clear water and high oxygen content. Pay attention to the supply of feed during the breeding period.

You must be wrong.

Yangcheng Lake hairy crabs have burrowing habits since the juvenile stage and like to crawl on the bottom. Sometimes they even go ashore to find food. They also like to live in water bodies with dense aquatic plants, abundant bait and fresh water. Therefore, artificial crab farming is to create a suitable ecological environment to facilitate the life and growth of Yangcheng Lake hairy crabs. Currently, one of the artificial breeding methods is to raise crabs in ponds.
