Does PMMSY give subsidy for RAS units and how do I apply?

Yes, RAS is a recognised component under PMMSY in many states, generally with around 40 percent subsidy for general category and around 60 percent for SC, ST and women beneficiaries on a fixed approved unit cost. Because RAS is expensive, the subsidy is on the department's fixed unit cost and not on your full actual spend, so your own contribution will still be large. The exact unit cost, your share and the eligible system size are decided by your state Fisheries department and change by state and year. Apply through your district Fisheries office, get the current approved cost in writing, and confirm the inspection and fund release steps before you build. Many farmers also pair this with a bank loan. Verify all figures locally and do not assume subsidy will cover the bulk of a RAS project.
