Foraging routes of Antarctic fur seals (Arctocephalus gazella) investigated by the concurrent use of satellite tracking and time-depth recorders
International audience Little is known about movement behaviour in terms of route choice in Antarctic fur seals (Arctocephalus gazella). We deployed satellite transmit- ters and time-depth recorders simultaneously on 11 animals, and time-depth recorders with a speed recorder on 10 animals, to invest...

International audience Little is known about movement behaviour in terms of route choice in Antarctic fur seals (Arctocephalus gazella).

The study took place during the 1997/1998 austral summer, and results indicate a preferred foraging area, with two main strat- egies in route choice apparent during foraging trips.
