Selecting Fish for Breeding in Aquaculture Fish Farming in Sri Lanka
Aquaculture is predicted to play a major and ever increasing role in meeting human needs for animal source food. In terrestrial animal and plant species genetic improvement programmes have made a substantial contribution to agricultural productivity and viability. As a result of decades of selective breeding and domestication in these terrestrial species, thousands of genetically distinct breeds, strains and varieties now exist worldwide and are collectively termed genetic resources.
Efficient breeding programs will be crucial to the development of fish farming, not only to achieve the necessary global demand, but also to reduce production costs, improve the resistance of farmed organisms to disease, improve food use and product quality . Aquatic animals allow the implementation of several approaches to genetic improvement. These include the hybridizations and cross-breeding, chromosome manipulation, sex control, transgenesis and selective breeding.
