Abstract

We review our studies on the influence of different temporal and spatial scales on changes in assemblage composition and patterns in feeding of fishes from a macrotidal mangrove estuary in north Brazil. The usefulness of different net types, hydro-acoustics, and visual censuses for scientific sampling in macrotidal mangrove estuaries is discussed. General differences in species richness, biomass and density between estuarine habitats were related to the shoreline gradient and the tidal stage. The major pulses of short-term dynamics in fish movements, changes in transient assemblage compositions and patterns in feeding were the tidal cycle, time of high water, and the spring/neap tide cycle. A comparison of the tide-to-tide, weekly, fortnightly and monthly variation between consecutive samples of abundance, catch weight, and species richness showed that the lowest variation in these parameters occurred among samples taken at spring tides. Recommendations for sampling strategies of long-term monitoring studies and for future research are given.
