However, maricuiture has caused direct and indirect negative impacts on the coastal ecosystem. To assess the impacts caused by a shrimp culture farm at the Goiana mangrove area the water and plankton community were studied. Samples were obtained from May11997 to Januaryll999, before and after the farm implantation. Mariculture facilities reduced around 20% of the mangrove area. An intensive mixture of the marine and freshwater fluxes occurred in the system, dominating the marine.
