Abstract

The differential use by croakers of connection inlets of the Chumpam-Balchacah system, adjacent to Términos lagoon, Campeche, was analized as a function of the seasonal and diel patterns of Bairdiella chrysura, B. ronchus and Micropogonias undulatus. 72 samples were obtained in July (rainy season) and October (stormy season) of 1991, and March (dry season) of 1992, in two sampling locations simultaneously. Fluctuations of density and biomass were related with the environmental behavior system. On the other hand, the differential abundance pattern between the inlets of the system suggest that the species have ecological strategies for minimizing competition between them. The nicthemeral variations of abundance of the sciaenid populations, showed significant statistical differences between inlets, reflecting diel changes of the utilization strategies. The utilization of Balchacah and Chumpam inlets by croakers is related to migration strategies from the sea or from Términos lagoon, because these represents recruitment, breeding and feeding areas.
