Ontogenic changes in the feeding ecology of the early life stages of the Antarctic silverfish (Pleuragramma antarcticum) documented by stable isotopes and diet analysis in the Dumont d'Urville Sea (East Antarctica)
International audience The feeding ecology of the notothenioid fish Pleuragramma antarcticum was studied in the Dumont d'Urville Sea (East Antarctica) near the French Antarctic station. Stable isotopes (d13C and d15N) and diet contents were used in order to study dietary shifts between fish lar...
