LIFE CYCLE MANAGEMENT

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.

Biological Features

  • Rostrum moderately long with 7-10 dorsal teeth and 2-4 ventral teeth . In mature males symmetric and semi petasma . Spermatophores complex , consisting of sperm mass encapsulated by sheath . Mature females are open thelycum . Six nauplii three proto - zoeas , and three mysis stages .
    Its color is usually white translucent , but may change depending on the substrate , food and water turbidity. Maximum size 23cm, maximum CL of 9 cm . Commonly females grow faster and become more than males.


    Habitat and Biology

    • Penaeus vannamei is found in tropical marine habitats. Adults live and breed in open water , while postlarvae migrate to the coast to spend the juvenile stage , the adolescent and adult pre estuaries , coastal lagoons and mangroves stage.

      Males mature from 20 g and females from the 28g in an age of between 6 and 7 months. When the Pacific white shrimp weighs between 30 and 45g releases between 100,000 and 250,000 eggs of about 0.22 mm in diameter. Hatching occurs about 16 hours after spawning and fertilization.

      The wild Penaeus vannamei seed was used in Latin America for extensive pond culture until late 1990. The programs of domestication and breeding allowed postlarvae more consistent high quality supply specific pathogen free ( SPF ) and / or resistant (SPR ) , which were reared in hatcheries . Some PL were shipped to Hawaii in 1989 , resulting in the production lines SPF and SPR and subsequently led to industrialization in the United States and Asia.
