Descrição: This study analyzed the relationship between Cynoscion acoupa productivity, relative to landings in the main commercial ports along the Brazilian Amazon coast, and environmental anomalies in the hydro-atmospheric-oceanic system, determining the influence of the environment on the success of the species' capture. Hydrological, meteoceanographic data, and climate indices were compared with landings (CPUE) between the years 1997 and 2007. These data were analyzed using the statistical methods of Generalized Additive Model and Wavelet Cross-Spectrum. The results indicated a high correlation between CPUE and environmental variables on an interannual scale, suggesting that variations in acoupa weakfish landings are mainly influenced by the seasonal effects and climate variability, which, in turn, are indirectly affected by the ENSO pattern. These changes affected SST and ocean currents, which influence the reproductive performance and seasonal migration of the species.
