Three years ago, a study of overfishing led to sharp
debate. It warned that the world's ocean fish could
be almost gone by the middle of the century. Now, a
new study offers more hope. It shows that the risk
of fisheries collapse has recently decreased in some
areas -- some, but not all.
Boris Worm at Dalhousie University in Canada and Ray
Hilborn at the University of Washington in Seattle
were lead authors of the new study.
Professor Worm also led the earlier study published
in two thousand six. Professor Hilborn publicly
disagreed with those findings. The result: the two
scientists agreed to work together on a new study.
They led a team that studied ten areas. In five of
them, the rate at which fish are being taken out of
the sea has dropped to a level that should let the
populations recover. Three areas still had
overfishing, but corrective measures have begun.
Yet, in all, almost two-thirds of fish populations
studied worldwide still need rebuilding.Only two
areas did not have an overfishing problem in either
the new study or the earlier one. They are New
Zealand and the American state of Alaska.
The new study found that overfishing has been
reduced in Canada's Newfoundland-Labrador area and
in Iceland and southern Australia. It also found
improvements in the northeastern United States and
the California Current that flows south along the
West Coast.
The study found that better controls are still
needed in the North Sea, the Baltic Sea and the Bay
of Biscay between France and Spain. The findings
from two years of research appear in the journal
Science.
Using nets that let smaller fish escape and agreeing
not to fish in certain areas can help reduce
overfishing. The study showed that these measures
helped fish populations grow in Kenya.
But one of the authors of the study, Tim McClanahan
from the Wildlife Conservation Society, says
fisheries in Africa face another threat. Most
countries in Africa, he says, are selling fishing
rights to industrialized nations which catch large
amounts of seafood.
The study shows what happened when industrialized
nations increased restrictions on fishing in their
own waters. Seafood companies moved their boats to
developing countries with fewer restrictions.
