Maturation of the wild females red-shrimp farfantepenaeus brasiliensis (crustácea: decapoda) in labotatory

Abstract

Farfantepenaeus brasiliensis wild females (56.89±12.36g) were captured and kept in a conventional unisex maturation system. Reproductive performance was assessed to evaluate this species potential for commercial production. Fourteen females were individually identified by plastic labels and uropod marks, following, by eye stalk ablation was carried out in. The number of spawns per female was 2.57 with a mean production of 71.08±41.26(x103) eggs per spawn and 187.86±131.53(x103) eggs per female. Total number of eggs produced was 2.63(x106). Fertilization rate was 68.42±42.2 %, with 73 % of the females presenting fertilized spawns. The nauplius to zoea metamorphosis rate was 86.11±32.98(%). Wild F. brasiliensis females have shown similar results to F. paulensis females, demonstrating that this species has great potential for Brazilian commercial shrimp culture.
