The cultivation of fish in net cages is an activity sensitive to environmental pollution, but also has the ability to cause environmental impact. The aim of study was to investigate spatial-temporal variations of physico-chemical and microbiological parameters of water quality (WQ) in a stretch of the Matapi River, State of Amapá/Brazil. This study presents an environmental analysis of fish culture on net cages systems, specially hydrodynamic and WQ condictions. Three sampling sites were distributed in ≈15 km of river to quantify variations of the WQ and hydrodynamic parameters. We notice a significant hydrodynamic seasonal influence of the WQ (p 0.05). We observed that both the hydrological-seasonal condictions, tide phase and site localization, explain the variation of WQ in these floodplans area (p<0.05, ANCOVA). We conclude that net cage system presented low environmental impact but local viability, both dependent on hydrodynamic conditions and scale studied.
