| Sumario: | Pseudopalaemon bouvieri undergoes complete abbreviated development. The reproductive cycle
(proportion and size of the sexually mature population and juvenile recruitment), fecundity and
egg size of this prawn were examined in three subtropical shallow lakes. The reproductive cycle
was seasonal; gonadal maturation occurred during the winter, ovigerous females were abundant
in the spring and breeding occurred at the end of spring. Females produced small numbers of
eggs (9–55) of relatively large sizes (1.0–2.1 mm). The proportion of ovigerous females with
respect to the total number of females, the fecundity and egg size differed among the lakes
according to the trophic state of the environments. Pseudopalaemon bouvieri has a reproductive
strategy similar to other Palaemonidae species that inhabit nutrient-poor inland waters. |
