India’s Cold Water Fisheries Emerging as a Key Pillar of the Blue Economy
Cold-water fisheries are practiced in high-altitude snow-fed rivers, streams, lakes, and reservoirs with temperatures ranging between 5°C and 25°C, dissolved oxygen above 6 mg/L, and pH levels between 6.5 and 8.0. Species such as rainbow trout, golden mahseer, and snow trout are cultivated using specialized infrastructure including hatcheries, raceways, RAS, biofloc systems, and cold chain facilities. Trout farming is generally practiced above 1,500 metres altitude, while mahseer culture is suitable at relatively lower elevations.
