Shrimp Penaeus (Litopenaeus *)

In 1973, the first reproduction of the Penaeus shrimp species was carried out (Litopenaeus *), this was made from nauplii nauplii from a female wild ovada captured in our country Panama.

After these results of great positivism that were obtained in the pond and the discovery of unilateral ablation (and adequate nutrition) to promote maturing in Panama in 1976, commercial cultivation of Penaeus vannamei started in Central and South America.

Penaeus vannamei is found in tropical marine habitats. Adults live and reproduce in the open sea, while the postlarva migrates to the coasts to pass the stage juvenile, adolescent and pre-adult stage in estuaries, coastal lagoons and mangroves. The males mature from 20 g and females from 28 g at an age of between 6 and 7 months.

When P. vannamei weighs between 30 and 45 g it releases between 100 000 and 250 000 eggs of approximately 0.22 mm in diameter. Incubation occurs approximately 16 hours after spawning and fertilization. In the first stage, the larva, called nauplio, nothing intermittently and is positive phototactic. Nauplii do not requirefeeding, but they are nourished by their embryonic reserve.

The following larval stages (protozoea, mysis and early postlarva respectively) continue to be planktonic for some time, they feed on phytoplankton and zooplankton, and are transported to the coast by tidal currents. The postlarvae (PL) they change their planktonic habits about 5 days after their metamorphosis to PL, theyThey move to the coast and begin to feed on benthic detritus, worms, bivalves and crustaceans.
