Length/mass relationships, energetic content and the otoliths of Antarctic cod Paranotothenia magellanica (Nototheniidae: Pisces) at sub-Antarctic Marion Island

Abstract

Relationships between otolith length and fish length, wet and dry mass and total energy are described for Antarctic cod Paranotothenia magellanica from Marion Island (sub-Antarctic Indian Ocean). The relationships were all highly significant and allow for more detailed and quantitative studies of the trophic structure of the area.
