WG-EMM-13

I would like to initiate discussions at this year’s WG-EMM that focus on how we are going to engage a larger group of scientists working for a greater proportion of the year to develop FBM. Part of these discussions should focus on the practicality of implementing FBM – what would the scheme look like on the ground, how could it be resourced and how to involve the fishery operators in our Read More

Adélie penguins (Pygoscelis adeliae) are a key Southern Ocean higher-order predator with a diet which is largely comprised of the fishery target species Antarctic krill (Euphausia superba). Being central-place foragers during the breeding season, their foraging range is restricted by the physiological, environmental and time constraints imposed upon them. Knowledge of their Read More

Antarctic krill fisheries have the potential to be in the top 10 fisheries of the world in terms of biomass production. The expansion of the fishery from current levels appears inevitable given the demand for protein and the efficiencies now being developed in the fishery.  CCAMLR is developing a feedback management procedure for these fisheries. Implementation of such a feedback Read More
