Abstract
[en] The rabbitfish Siganus sutor is heavily fished for consumption in the Great Reef of Toliara, Madagascar. From a conservation perspective, it is important to know more about the bio-ecology of this species. In this study, the isotope ratios of nitrogen, carbon and sulphur are studied in order to obtain information on the trophic level and diet of S. sutor.
