The reproductive biology of Macrobrachium brasiliense (Decapoda: Palaemonidae) was studied based on 2,604 specimens collected from October 1994 to August 1995, in two forest streams along the Iquitos-Nauta, highway in Loreto (Peruvian Amazon).The female: male sex ratio was 1.7:1. M. brasiliense showed sexual dimorphism in the cephalotorax length, females being slighthly smaller than males. Reproduction was contínuos with a reproductive peak between April and June. Fecundity ranged from 15 to 168 eggs per female. A significant relationship was observed between fecundity and cephalotoraxic length and the weight. Egg volume presented no significant relationship with cephalotoraxic length or fecundity. |
