Top predators and stable isotopes document the cephalopod fauna and its trophic relationships in Kerguelen waters

Yves Cherel, Nicolas Gasco & Guy Duhamel
Information on the poorly known but ecologically important cephalopod fauna of Subantarctic islands was collected using fishery bycatches, together with published data from oceanographic cruises and top predators (fishes and seabirds) as biological samplers. Overall, the cephalopod fauna from Kerguelen Islands includes at least 38 different species. Oegopsid squids dominate the assemblage over octopods (31 and 6 taxa, respectively), with one species of sepiolid occurring over the shelf. This rich community includes a large diversity...
