Key areas
Shrimp farming in Tamil Nadu is concentrated along the eastern coast. Nagapattinam and Thanjavur districts are traditional hubs, with Cuddalore and northern coastal districts also active. The state's processing and export infrastructure supports the sector.
Water and seasons
- Brackish water from coastal estuaries and creeks.
