Reproductive pattern of the freshwater prawn pseudopalaemon bouvieri (crustacea, palaemonidae) from hypo-osmotic shallow lakes of Corrientes Argentina

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;...

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. Pseudopalaemon bouvieri tiene un desarrollo completamente abreviado. Fueron examinados el ciclo reproductivo (proporción y tamaño de la población sexualmente madura y el reclutamiento de los juveniles), la fecundidad y el tamaño de los huevos de este camarón en tres lagos subtropicales poco profundos. El ciclo reproductivo fue estacional; la maduración gonadal ocurrió durante el invierno, las hembras ovígeras fueron abundantes en primavera y las crías aparecieron a finales de la primavera. Las hembras producen un bajo número de huevos (9 - 55) de tamaño relativamente grande (1,0 - 2,1 mm). La proporción de hembras ovígeras con respecto al número total de hembras, fecundidad y el tamaño de los huevos difirieron entre los lagos, de acuerdo al estado trófico de los ambientes. Pseudopalaemon bouvieri tiene una estrategia reproductiva similar a otros Palaemonidae que habitan ambientes acuáticos continentales pobres en nutrientes. 2022-02-01T12:43:44Z 2022-02-01T12:43:44Z 2016 Artículo Carnevali, Romina Patricia, Collins, Pablo A. y Poi, Alicia Susana Guadalupe, 2016.
