💡 Key Idea

India's Coastal Waters: Natural Nurseries for Shellfish

Nature's hatchery along the coast.

India's coastal water bodies act as natural nurseries, offering ecological niches for many culturable shellfish species. They are known for abundant seed resources of shrimp, crab, lobster, mussel, and oyster.

↳ Coastal waters are nature's shellfish hatcheries.

⭐ Important Fact

West Coast Leads Shrimp Production

80% from the west.

The west coast of India constitutes 80% of shrimp production. Although 11 shrimp species are available, only three are mainly cultivated: Penaeus monodon, P. indicus, and P. semisulcatus.

↳ West coast dominates shrimp production; three species are key.

⚙️ Process

Shrimp Lifecycle: Offshore Breeding to Coastal Nurseries

From deep sea to estuaries.

↳ Shrimp breed offshore; larvae migrate to coastal nurseries.
