Mud crab aquaculture program of ICAR-Central Institute of Brackishwater Aquaculture reached a milestone in crab farming in earthen ponds with a harvest from hatchery reared mud crab instars (~2 g) to marketable size crabs (above 500 g) within 165 days. A production of 70 kg with an average body weight of 720 g was achieved. The survival rate was 45% reasonably high for mud crabs, from a rearing density of 300 crabs per acre pond. The produce yielded ₹1, 10, 250 for the beneficiaries.
