The Coastal Aquaculture Authority (CAA) is a statutory body under India’s Ministry of Fisheries, Animal Husbandry and Dairying, created by the Coastal Aquaculture Authority Act, 2005. CAA regulates coastal aquaculture in the country’s coastal zones through registration of farms and hatcheries, environmental safeguards, siting rules, antibiotic and effluent standards, and inspections. It issues guidelines on biosecurity, responsible use of inputs, and sustainable practices, and works with state governments and research institutes to balance aquaculture growth with coastal-ecosystem protection.
