Pangasius production has greatly expanded in India covering over 42,500 ha of ponds and tanks and also 2500 cages. It is mostly produced in small ponds (0.4 ha) by small farmers commonly producing 40-45 tons/ha but larger ponds above 4 ha having 1.5 to 2 m deep are many producing 80-85 tons/ha. West Bengal is the main hub of seed production, supplying over 700 million fry, while few commercial nurseries and hatcheries have recently come up in the states of Andhra Pradesh, Chhattisgarh, Odisha and of late Uttar Pradesh.
