ARGAEZ-GARCIA, Nelly; GUILLEN-HERNANDEZ, Sergio  e  AGUIRRE-MACEDO, M. Leopoldina. Intestinal helminths of Lutjanus griseus (Perciformes: Lutjanidae) from three environments in Yucatán (Mexico), with a checklist of its parasites in the Gulf of Mexico and Caribbean region. Rev. Mex. Biodiv. [online]. 2010, vol.81, n.3, pp.903-912. ISSN 2007-8706.

A survey of intestinal helminth parasites of the gray snapper, Lutjanus griseus, collected at the estuarine coastal lagoon of Celestún and off the coast of the localities of Chelem and Progreso (Yucatán, Mexico) is presented together with a checklist of gray snapper intestinal helminths in the Gulf of Mexico and the Caribben region. Twenty helminth species were found at the Yucatán localities. Eigth of these have previously been reported in the Gulf of Mexico and the Caribbean region and 12 are new records for L. griseus, which increases the number of species recorded for gray snapper in the region to 44. Only 8 helminth species were recorded from fishes collected inside the coastal lagoon, while all 20 were found in fishes from offshore. Differences in species composition and infection parameters of each helminth species between both habitats are presented and discussed, together with similarities in species composition of the intestinal helminth fauna of L. griseus from Yucatán with those reported for the same host species in the Atlantic coast of USA, the Gulf of Mexico and the Caribbean regions.
