Reproductive strategy of Brachidontes rodriguezii (Bivalvia: Mytiloida) in the South-western Atlantic Ocean
This study consisted in the characterization of reproductive aspects such as oocytes morphology, temporal variation in size and frequency of oocytes and the reproductive cycle of the mussel Brachidontes rodriguezii. This species dominates the rocky intertidal coast of Buenos Aires province, Argentin...
