Using small Antillean Z-style fish traps, 962 fish of 23 species from 15 families were trapped over 1128 trapping days, at an overall rate of 0.85 fish per trap per day. Catches by numbers were dominated by 2 genera: Acanthropagrus (51.8 percent) and Epinephelus (20.3 percent). In trap catches, the total number of fish, the number of species, and the numbers of individuals of the most common species showed a general decline towards the upper areas of the estuary and generally were higher in 'snag' habitats.
