Lipid components as a measure of nutritional condition in fish larvae (Pleuragramma antarcticum) in East Antarctica
International audience Pleuragramma antarcticum is a key component of the neritic assemblages in the Antarctic coastal waters. Larvae of this species were sampled from 2008 to 2011 in the Dumont d'Urville Sea (East Antarctica). The lipid class composition [triacylglycerols (TAG), cholesterol (C...
