Satellites
scanning the oceans are a valuable new tool to protect sharks, according to
scientists.
A review
of evidence suggests endangered sharks can be protected from threats such as
illegal fishing, using the technology.
Whales,
turtles and birds are already being monitored from space, raising hopes that
the technique can be applied in the conservation of other species.
Many
sharks are on the brink of extinction.
Populations
of sharks, rays and skates (elasmobranchs) have declined dramatically over the
past 50 years.
"New
technologies such as this are going to be really important to the conservation
of sharks," said Michael Williamson of the Zoological Society London (ZSL)
and King's College, London.
Over-fishing
is one of the biggest causes of the decline in sharks, through accidental or
illegal targeting.
