Although only 10% of world aquaculture production is currently based on genetically improved stocks, the dramatic gains achieved in species such as Atlantic salmon and tilapia serve to demonstrate the potential of selective breeding to improve growth, product quality, disease resistance and other commercially important traits. As increasing pressure is placed on feed, land and water resources, there is a growing need for...
