Resumen: "Pomacea flagellata is a gastropod conspicuous in freshwater environments, and represents a fishing resource. To assess their abundance, distribution, and secondary production, monthly samplings were carried out in Bacalar Lake from June 2012 to May 2013 at 12 sampling sites. In each site, three random transects were marked parallel to the shore. All snails on transect were collected and shell length and wet weight measured. The highest density occurred in September (1.27 ind.m-2), lowest in October (0.47 ind.m-2). Shell lengths ranged from 2 to 56 mm, with recruitment in January–March. Growth parameters were L8 59.50 mm, K 0.65.year-1"
