Abstract
Mariculture has become an important source of human food and its production is
likely to expand well in Brazil for the foreseeable future. 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.
