Review: the energetic value of zooplankton and nekton species of the Southern Ocean
International audience Understanding the energy flux through food webs is important for estimating the capacity of marine ecosystems to supportstocks of living resources. The energy density of species involved in trophic energy transfer has been measured in a largenumber of small studies, scattered...

International audience Understanding the energy flux through food webs is important for estimating the capacity of marine ecosystems to supportstocks of living resources. The energy density of species involved in trophic energy transfer has been measured in a largenumber of small studies, scattered over a 40-year publication record. Here, we reviewed energy density records of SouthernOcean zooplankton, nekton and several benthic taxa, including previously unpublished data. Comparing measured taxa,energy densities were highest in myctophid fishes (ranging from 17.1 to 39.3 kJ g−1 DW), intermediate in crustaceans (7.1to 25.3 kJ g−1 DW), squid (16.2 to 24.0 kJ g−1 DW) and other fish families (14.8 to 29.9 kJ g−1 DW), and lowest in jellyfish (10.8 to 18.0 kJ g−1 DW), polychaetes (9.2 to 14.2 kJ g−1 DW) and chaetognaths (5.0–11.7 kJ g−1 DW).
