Hardening crabs in floating cages
You can make a cage from bamboo to contain the crabs. Soft crabs must be separated so they do not fight and damage each other. Give each crab half of a tiny fish per day. If the crab has not eaten its food, it is sick and must be removed. In 10 to 15 days, the crabs will have a hard shell and can be sold.
