Reproductive Biology of Mytilopsis leucophaeata (Conrad, 1831) (Bivalvia: Dreissenidae) of Tampamachoco Lagoon, Tuxpan-Veracruz. Int. J. Morphol. [online]. 2012, vol.30, n.4, pp.1526-1531.

The reproductive cycle of Mytilopsis leucophaeata (Conrad, 1831) was characterized in organisms collected monthly during an annual cycle in Tampamachoco lagoon Tuxpam-Veracruz, located on the coast of the Gulf of Mexico in the Terrestre Prioritaria Region (RTP-103) of CONABIO considered a RAMSAR 1602 site in Mexico. Histological results indicated that M. leucophaeata has four gametogenic stages: gamete, maturity, female's total spawning and partial expulsion inmales. One of the main factors that influence the synchronous spawning gametes in both males and females is salinity, in the months of January to March.
