An exotic species is any species, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that habitat. During the period 1870-1947 under the British rule, 9 species of exotic fishes were introduced. They were temperate food carps, Tinca tinca, Carassius carassius, Cyprinus carpio (European strain), and the tropical osphronemid, Osphronemus goramy; the salmonid game fishes, the brown trout and the rainbow trout and larvicidal Gambusia affinis and Lebistes reticulatus. The post- independence India witnessed introductions of 8 exotic species. They were the cyprinids, Cyprinus carpio, (chinese strain), Ctenopharyngodon idella, Hypophthalmicthys molitrix, Puntius javanicus, and the cichlid, Tilapia mossambica, all of food species and the salmonids, Salvelinus fontinalis, Onchorhyncus nerka, and Salmo salar.
