Abstract


Fish and fish products were always a commodity in human nutrition. Aquaculture resources of natural continental or maritime waters permanently secured human food needs, but today, under the global population explosion, humanity may destroy the balance of existing ecosystems by exploiting their irrational considerations to which attention is directed to aquaculture specialists, knowing that real progress in recent years. In this economic stage, a fierce commercial competition and significantly reduce the market price, and achieving alignment implies a new concept of strategy to lower production cost, which ends with the use of improved genetic lines. Genetic improvement programs correctly applied in accordance with existing species and environmental conditions will help increase the performance of production and reproduction of fish and getting a low production cost, benefiting in this respect, both producers and consumers.
