Genetic improvement and development of good production systems have improved the productive performance and competitiveness of different species. In the past 50 years , the efficiency of distinguishing between desirable and undesirable players has been developed , which dramatic changes in the productive performance of farm animals have been described .
This tool has been applied to aquaculture species by CENIACUA , which has managed to develop excellent genetic lines for growth and disease resistance in P. vannamei . Further improvement in shrimp CENIACUA , has entered its research on fish such as tilapia and ultimately conducts studies in marine fish.
