Culture Fishery is the raising of fishes in tanks and ponds while capture fishery is management of catching fish without actually raising them In this method, extract of pituitary hormone is injected into male and female breeder fish. Two males and one female are then kept in a breeding happa, a bamboo and cloth container. Spawning takes place in 3-6 hours. The fertilized eggs are removed and kept in hatchery, where they hatch in 15-18 hours. The hatchlings are kept in glass-jar hatcheries. A mouth is formed on the third day and the young fish are now called fry. They are kept in rearing ponds for about three months, where they grow into 4"-6" long fingerlings. The fingerlings are then released into stocking ponds where they grow to the required size. In composite fish culture, different species of fish like Catia, Rohu and mrigal are cultured together.
