Abstract
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 ofa 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.

Summary
Las lagunas costeras son consideradas entre los ecosistemas de mayor productividad en el planeta y las mismas representan áreas de gran potencial pesquero. Si bien se puede establecer la importancia de cada ítem con este primer índice (IRI1), se calculó un segundo IRI2, donde si se toman en cuenta los valores de Fn, lo que hace más confiable el cálculo, al menos para estos ítems.
