Spatially explicit food web modelling to consider fisheries impacts and ecosystem representation within Marine Protected Areas on the Kerguelen Plateau
Abstract The Kerguelen Plateau in the Indian sector of the Southern Ocean is a highly dynamic region for Southern Ocean ecosystems and an important region for the Patagonian toothfish fishery. Fished regions overlap with foraging regions for predators; however, no study has explored the spatial impa...

Abstract The Kerguelen Plateau in the Indian sector of the Southern Ocean is a highly dynamic region for Southern Ocean ecosystems and an important region for the Patagonian toothfish fishery.

Our study provides valuable insights into spatial ecosystem dynamics on the Kerguelen Plateau; however, our interpretations were limited and more research is needed to disentangle the natural variation from fishing impacts and further explore spatio-temporal changes in phytoplankton on the ecosystem. |
