                         Jaguaribe River estuary, harboring large shrimp farms, and in the 
                         more pristine Pacot{\'{\i}} River estuary. Normalized Difference 
                         Vegetation Index (NDVI) was used to compare the overall health of 
                         the forests. Measures of suspended matter (TSS), total (TP), 
                         particulate (PartP) and soluble reactive phosphorus (SRP) in the 
                         infl ow and outfl ow waters of tidal channels draining the 
                         mangroves were performed during tidal cycles. NDVI varied from 
                         0.65 in the Jaguaribe estuary to 0.85 in the Pacot{\'{\i}}, 
                         suggesting the impact of shrimp farm effl uents on mangrove canopy 
                         cover. The shrimp farm infl uenced site showed 10 times larger 
                         absolute \∑P (TP + PartP + SRP) = 1.2-5.2 kg.hr-1) fl ux 
                         than the pristine site (\∑P = 0.22 kg.hr-1). Tidal balances 
                         showed smaller retentions of the total infl ux: 28-54%; 44-45%; 
                         38-65% and 8-53% for TSS; TP; SRP; and PartP respectively, in the 
                         shrimp farm infl uenced site to over 93% of the total tidal input 
                         of TSS and all P fractions in the pristine mangrove. This suggests 
                         that mangrove phosphorus accumulation is decreased in the forest 
                         with lower NDVI and limits mangroves potential as a natural 
                         barrier to the nutrient transport to adjacent estuarine and 
                         coastal waters.",
