Hi all,

Pleased to share a new publication out in Scientific Reports, on the movement ecology of male Antarctic fur seals along the Western Antarctic Peninsula, their interaction with the krill fishery and possible impacts on bioindicator species used by CCAMLR. The publication is open access and available here:


Male Antarctic fur seals: neglected food competitors of bioindicator species in the context of an increasing Antarctic krill fishery

A.D. Lowther, I. Staniland, C. Lydersen & K. M. Kovacs

The fishery for Antarctic krill is currently managed using a precautionary, ecosystem-based approach
to limiting catch, with performance indices from a long-term monitoring program focused on several
krill-dependent predators that are used to track ecosystem health. Concerns over increased fishing
in concentrated areas and ongoing efforts to establish a Marine Protected Area along the Peninsula,
a key fishing region, is driving the development of an adaptive management system for the fishery.
The cumulative effects of fishing effort and interactions among krill-dependent predators and their
performance is at present neglected in the CCAMLR Ecosystem Monitoring Program. However, we
show considerable overlap between male Antarctic fur seals and the krill fishery in a complex mosaic,
suggesting potential for cumulative impacts on other krill dependent predators. A holistic view is
required as part of future efforts to manage the krill fishery that incorporates various sources of
potential impacts on the performance of bioindicator species, including the fishery and its interactions
with various krill dependent predators.
