CANTO-MAZA, Walter Gabriel  and  VEGA-CENDEJAS, María Eugenia. Hábitos alimenticios del pez Lagodon rhomboides (Perciformes: Sparidae) en la laguna costera de Chelem, Yucatán, México. Rev. biol. trop [online]. 2008, vol.56, n.4, pp.1837-1846. ISSN 0034-7744.

Feeding habits of the fish Lagodon rhomboides (Perciformes: Sparidae) at the coastal lagoon of Chelem, Yucatán, México. Stomach contents of Lagodon rhomboides, the most abundant fish species from seagrass beds in Chelem Lagoon, Yucatan, Mexico, were analyzed. The specimens were collected using a beach seine at eight stations distributed randomly in the lagoon during July, September and November 2002. The trophic components were analyzed by means of the relative abundance (%A) and frequency of occurrence (FO) indices. The trophic similarity between different ontogenetic stages was determined using the Bray-Curtis Index. A total of 90 stomach contents were analyzed. This species is omnivorous, including vegetal and animal material and has a wide trophic spectrum with 58 alimentary items. Trophic ontogenetic variation was significant with a transition from one feeding stage to the next. Small individuals (4.0 -8.0 cm LE) preferentially consume plankton preys and microcrustaceans, while in bigger sizes, the macrocrustaceans, annelids and macrophytes were the main food. Rev. Biol. Trop. 56 (4): 1837-1846. Epub 2008 December 12.
