Avaliação do impacto ambiental da subsidência na Lagoa Mundaú na produtividade de sururu

Abstract

The sururu, a species of mussel native to Lagoa Mundaú and recognized as Cultural Heritage of the State of Alagoas, is the main source of food and income for the population that lives near the lagoon, and is also considerably sensitive to changes in salinity in its environment. The salinity in the estuary depends on many factors and one of them is the morphology of the lagoon, in the case of an eventual alteration in the bottom of the Lagoon, increasing its depth, the salinity levels of the estuary would be affected. Knowing that there is a process of subsidence taking place on the shores of the Lagoon, possibly caused by mineral extraction of rock salt and earthquakes, which also occurred in the area of Lagoa Mundaú, there is a need to investigate this phenomenon and its possible impact on salinity, and consequently, in the sururu population. This work intends to estimate possible scenarios, different periods of time, in case there is a sinking in the lagoon region and how this affects the population and production of sururu.
