Proporción sexual y hermafroditismo del molusco, Anadara tuberculosa (Bivalvia: Arcidae) en Panamá

Abstract: Introducción: El bivalvo Anadara tuberculosa es un recurso pesquero y económico importante en el Pacífico Este Tropical. La proporción sexual varia a lo largo de su área de distribución, con casos de aparición de hermafroditismo, ocasional para algunas poblaciones, normal en otras. Estas características podrían ser una respuesta a presiones antropogénicas y ambientales. Objetivo: Evaluar la proporción sexual y el hermafroditismo en la especie en el Pacífico de Panamá. Métodos: Se analizó información reproducti… Show more

“…In this context, Panta-Vélez et al [14] mentioned that the protandry hermaphroditism of the species may be associated with the imbalance in sexual proportion, since the reproductive activity of A. tuberculosa as regards sexual maturity is not coherent with that measured in other areas of the Ecuadorian Pacific. In addition, the emergence of protandry hermaphroditism and changes in sex ratio indicate that the population may respond to anthropogenic and environmental pressures [5,12]. The numerical superiority between females and males may also be caused by the physicochemical properties of the water, which favor the development of females or interfere with the development of males, as mentioned by Guilbert [36].…”

“…They inhabit the intertidal zone, are often buried in mud, associate with mangrove ecosystems, and share a habitat with other bivalve species, such as A. multicostata and A. similis [2,3]. A. tuberculosa is characterized by protandrical sequential hermaphrodite behavior influenced by anthropogenic and environmental pressures [4,5].…”
