SOME of the world’s rarest seabirds could be under renewed
threat in Scotland
following the controversial decision to ban fishing fleets from dumping
unwanted fish.
European Union countries voted last week to outlaw the
discarding of millions of tonnes of dead or dying fish which are thrown back
into the sea because they have been caught in excess of strict quotas.
But while the move should help safeguard fish stocks in
the long term, experts fear the change will seriously reduce populations of
birds such as great skuas, which have come to rely on discards as a key source
of food.
Most of the world’s 16,000 remaining great skuas are in Scotland , where
they are known as bonxies. They have eaten discards for decades since
overfishing reduced levels of sandeels, their natural prey.
Ornithologists warn that phasing out discards also poses a
threat to other endangered seabirds. Previous moves to limit wasted catches in
the North Sea led to an increase in great
skuas switching to killing smaller seabirds for food, particularly the
black-legged kittiwake.
Environmental groups now want the Scottish Government to
formally designate a network of marine protected areas around the coastline to
protect sandeel stocks and provide more natural food for species such as the
skua.
RSPB Scotland, which has commissioned research into the
impact of the ban, stressed that while it supports the decision it is concerned
about the potential effects in the short term.
