Abstract
Abundance patterns of dominant fishes species in La Esperanza lagoon in the three climatic periods, rainy, "nortes", and dry, were analyzed. Ten fish collections were made from September 2001 to June 2002. Samples were obtained by otter trawl. Salinity range from 36 % in September 2001 to 18 % in November 2001, and temperature were among 30°C in September 2001 and 23°C in February 2002. Community was formed by 37 fish species corresponding to 23 families. Dominant species were: Eugerres plumieri, Sphoeroides testudineus, Cathorups melanopus, Archosargus rhomboidalis, and Bairdiella chrysura. Fluctuations of density, biomass, and frequency of this species in the studied area were related with the environmental behavior system, except S. testudineus and A. rhomboidalis which behavior resulted independent from salinity and temperature variations. Dominant fish species in the studied area developed behavioral strategies than minimized inter specific competition.
