Resumo

CANCHE-CANCHE, Vasti E.  e  CASTELLANOS-OSORIO, Iván. Medusae (Cnidaria) of Bahia de la Ascension, Quintana Roo, Mexico (1997). Hidrobiológica [online]. 2005, vol.15, n.1, pp.65-72. ISSN 0188-8897.

From 75 zooplankton samples collected during february-december 1997 in Ascension Bay, Quintana Roo, Mexico, the distribution, composition, and abundance of the medusan fauna were analyzed. Fifteen species were identified; Clytia mccradyi was the most abundant, followed by Helgicirrha schulzei. Thirteen of them represent new geographic records for the Ascension Bay. The highest medusan densities were recorded in December (16661 org/1000 m3) and February (10714 org/1000 m3). The lowest numbers of species were registered in stations 2, 7 and 12 (9, 6 and 7 species, respectively). The local medusan fauna was represented by a mixture of neritic and oceanic forms which distribution is probably influenced by local circulation patterns
