Seaweed cultivation in India involves the farming of marine algae along coastal regions for use in agriculture, food, pharmaceuticals, cosmetics, and industrial applications. The process includes site selection, seed preparation, rope or raft-based cultivation methods, regular monitoring, and harvesting under suitable marine conditions. Seaweed farming supports coastal livelihoods, promotes sustainable aquaculture practices, and contributes to soil health, biofertilizers, and raw material supply for multiple sectors while aligning with marine ecosystem management frameworks.
