Breeding and Rearing of Common carp, Cyprinus carpio (Linnaeus 1758)

Climate of Pakistan is arid and semiarid with unusual and uneven rainfall. Abundant land is affected with salinity and water-logging and the sub soil or underground water become brackish/ saline. These places can be utilized for fish culture which will act as a tool for desalinization of the soil through brackish water fish farming. Due to the influence of climate change circumstances, intrusion of sea water into coastal inland areas rapidly and freshwater scarcity because of less precipitation, agriculture lands are disturbed and didn't give profit. Major carps also under stress in saline waters didn't give better yield. It is serious issue to utilize that land for fish farming instead of agriculture and to verify a source of less priced and excellent protein quality (animal origin) in future. Salinity of water is an environmental element which effect on growing efficiency of many fish species cultured in ponds, tanks, raceways, and net cages. The present study reports to investigate suitable range of salinity for desire growth, feed utilization, meat quality and survival ratio of Common carp in controlled conditions.
