Laboratoire d'Ichtyologie Appliquée Ecole Nationale Supérieure Agronomique 145, avenue de Muret, 31076 Toulouse cédex
Ce travail rassemble des données anciennes et récentes sur la géographie et l'évolution du lac Alaotra situé sur les hauts plateaux malgaches. Ce lac, d'origine tectonique, est le vestige d'un lac beaucoup plus grand, sur le point de disparaître à l'échelle des temps géologiques. Il se présente actuellement comme un grand étang dont le processus de comblement s'est accéléré ces dernières années à cause d'activités humaines sur le littoral.
Abstract
The present study brings together past and recent information on the geography and evolution of Lake Alaotra which is situated on the high plateau of Madagascar. The lake is of tectonic origin and is the remnant of a much larger that is on the point of extinction in terms of geological time. It exists now as a large pond and the process of infilling has been accelerated in recent years by human activity in the littoral region.
