RODRIGUEZ, José  and  VILLAMIZAR, Estrella. Alimentación del pez tropical Gobioides broussonnetii (Pisces: Gobiidae) en la Laguna de Unare, Venezuela. Rev. biol. trop [online]. 2006, vol.54, n.4, pp.1093-1098. ISSN 0034-7744.

Diet of the tropical fish Gobioides broussonnetii (Pisces: Gobiidae) at Laguna de Unare, Venezuela. Unare Lagoon is one of the most important fishery coastal ecosystems in Venezuela. For the past  10 years, changes in its hydrological regime have affected the physiochemical characteristics of the water with important consequences on its faunal composition and abundance. An example of such variation is the abundant presence of a fish species, Gobioides broussonnetii, recently registered in this ecosystem. The ecology of this species must be studied to identify new ecological processes occurring in the lagoon. Detritus is the most important component of the G. broussonnetii diet, followed by plant and animal items. The species is a primary detritivorous consumer and this may be associated with its activity pattern (morning): It may be an occasional visitor because it was not captured regularly in the monthly samplings. Rev. Biol. Trop. 54 (4): 1093-1098. Epub 2006 Dec. 15.

Keywords : Gobioides broussonnetii; detritivorous; coastal lagoon; diet; trophic status.
