According to the Population Division of the United Nations, world population reached 6,500 million in 2005 and will continue growing by more than 76 million per year, United Nations estimates indicate that by 2050 there will be between 7,700 million and 10,600 million, being the most likely projection of 9,100 million inhabitants. The availability of arable land and increased efficiency in food production from land can reach their limits. The oceanographic conditions, climate and its effect on soil quality and various human uses to determine crop land will be unable to provide food for the ever growing human population. On the other hand, it is recognized, therefore, that marine and freshwater aquatic, covering over 70% of the planet's surface, are a reservoir of food substances, industrial and biomedical importance, and also a source of degradation and dilution of anthropogenic and industrial waste (Solar, 2002).

Statistics of the United Nations Organization for Food and Agriculture Organization (FAO, 2002) indicate that the production of food from the aquatic environment is close to 137 million metric tons, of which almost 31% came from farming activities. The FAO also estimates that to meet the needs of the human population of 2025, total production should increase to 165 million metric tons. This significant increase can not come from the catch of wild species without causing serious damage to marine ecosystems, lakes and rivers. Consequently, the increase in the production of seafood must necessarily come from a significant increase in the efficiency of crops. The world's most populous countries like China, India and Indonesia, or those lacking sufficient arable land areas, such as Japan, are turning mainly to aquaculture ...

... cultivation of red abalone mollusks such as oysters, mussels and mussel, found in 400 sites assessment more, excluding exempt holders of the patent only aquaculture. Despite this large number of schools working towards its cultivation, attempts have been unsuccessful, mainly due to the lack of studies regarding its development (Osorio et al., 1979), reproduction (Cancino & Becerra, 1978; Solis & Lozada, 1971), and larval settlement (Ramorino & Campos, 1983), acclimation to culture conditions (Cancino & Becerra, 1978), feeding, disease control (FIP, 1997) and basic genetic studies (Astete, 1995; Martínez-Lage et al., 2002, Martínez-Lage et al., 2005, Mena et al., 2001; Thiriot-Quievreux, 1984 Toro, 1998), which has led to seriously endanger the existence of natural banks and populations, adding to this the lack of management plans for resource extraction activities.
