Resumen:
The interactions between seabirds and Wsheries
pose signiWcant threats for the seabird species such as incidental
capture. In contrast, several species of seabirds meet
part of their energetic requirements through the use of Wsheries
discards. Knowledge about the relationship between
at-sea distribution of Procellariiformes and Wsheries is a
key tool in marine ecosystem management. We analysed
the spatio-temporal relationship between the areas used by
16 satellite-tracked breeding adults of the Southern Giant
Petrel and Wsheries distribution and catch at the Patagonian
Shelf. We also determined the time spent by adults in
diVerent marine jurisdictions. Results indicated a marked
spatio-temporal association between birds and Wsheries,
mainly trawlers. The Southern Giant Petrels concentrated
their foraging eVort over Argentinean waters. The use of
an abundant and predictable food source provided by theWsheries
