ABSTRACT
In India, carp culture accounts for more than 80% of production in freshwater aquaculture. The main reason for this is induced carp spawning was successful during late 1950’s following that, during post-independence period many steps were taken by the Government of India and more areas were brought under aquaculture to increase fish production. The stunted fishes grow bigger and faster in the grow out ponds and catla can grow up to 1.5 kg within 6 months period. Selective breeding technique is the method of choice for increasing growth in fishes. It aims to produce genetically higher quality cross bred fishes. Domestication is the most important method having impact on genetic diversity. Induced breeding in an artificial or controlled environment and arresting of breeding in an unconditioned environment are the important factor in domestication. Domestication was mainly carried out in fishes such as common carps and Atlantic salmon.
