Measures of Conservation

The Antillean manatee was included in the federal list of species in danger of extinction in the 1967. In order to reduce the causes of deaths ofmanatees it is necessary to regulate the speed of boats and "jet skis" so that the collisions with these can be avoided. Also the agencies must take measures to make sure that construction projectsnear the coast do not affect them, as it happens with the erosion towards the sea caused by the earthwork or the direct contamination of waters with chemical agents. The erosion often causes that thequality of cost near waters diminishes, affecting the submarine vegetation on which the manatees are fed.
