Mysidacés (Crustacea) de Kerguelen, Crozet et Bouvet (Océan Austral) récoltés par la Japonaise, le Marion-Dufresne (1972–82) et dans des contenus stomacaux d'oiseaux

Abstract

This study deals with the Mysidacea (Crustacea) collected during the cruises organized by T.A.A.F. (Terres Australes et Antarctiques Francaises), between 1972 and 1982, in the subantarctic part of the Southern Ocean, off Bouvet, Marion, Prince Edward, Crozet, Kerguelen and Heard Islands. In spite of the large numbers of samples taken between the littoral and 2000 m, with various bottom sampling gears, only 8 species were caught. At the Kerguelen islands, the genus Mysidetes, with 2 species including M. morbihanensis n. sp., was the main constituent of the benthic littoral mysidacean fauna, while Boreomysis inermis was the main bathyal species. The analysis of stomach contents of birds indicates that some bathypelagic mysidacean species ascend to the surface layer.
