ResumoThe Mar Menor is a mediterranean hypersaline coastal lagoon that supports important fisheries and is the object of an intense tourist development. The effects of recent human activities in the Mar Menor, including enlargement of a channel of communication with the open sea and dredging and deposition of sand to make beaches, are studied. Some of these effects are colonization by new marine species, the spreading of stands of Caulerpa prolifera and increase of silt-clay fraction and organic carbon in the sediments. Some of these processes result in fall in the fisheries stocks of some species and in a decreasing attractiveness for tourists in the area.
