Induced breeding

Making farmed fish spawn by injecting hormones; India's first success with carps, in 1957, freed farmers from river-caught seed.

Also: hypophysation

Indian major carps do not spawn in still ponds; in the wild they need monsoon floods. For centuries farmers collected their fertilised eggs and spawn from rivers. On 10 July 1957, the scientists Hiralal Chaudhuri and K. H. Alikunhi of the Central Inland Fisheries Research Institute bred carps in Odisha by injecting them with extract of fish pituitary glands, a method called hypophysation. It let hatcheries produce seed on demand and opened the way for India's fish farming boom. India marks 10 July as National Fish Farmers' Day.
