From 2001 CENIACUA has been cultivated in concrete tanks P. vannamei broodstock at high densities under the system of bacterial floc . In 2003 comes into operation module brood rearing conditions under superintensive liner pools with the same type of culture that is characterized by densities 70-150 / m2, minimal water exchange , intense aeration, water mixing and proliferation heterotrophic bacteria. The average yield of these crops is 25,500 kg / ha / year. The reasons to think these systems are basically increasing environmental pressures for the rational use of water, effluent control , land constraints and biosecurity.
