Overfishing is recognized as a problem
that needs to be dealt with at international as well as national level
to protect fish stocks and entire ecosystems. Overall, there is a need
to reduce fishing pressure in order to maintain or restore degraded
marine environments to healthy ecosystems that include rich fish communities.
If policymakers have the political will to change the future of fisheries,
there are a number of options available to them, including:
reduced quotas;
phase-out
of subsidies;
fishery closures;
improved monitoring
and enforcement of local and international fishing regulations through
increased budgets and reduced levels of corruption; and
the establishment
of marine protected areas (MPAs).
The European Commission recognized that certain marine stocks, including
herring, cod, and hake, were being overexploited in the North Sea. In
February 2003, measures came into force reducing fishing pressure in
the area. One of the major pieces of legislation agreed was a maximum
of 15 days per month for vessels fishing in restricted areas. This took
into account both the conservation of stocks and also the economic reality
of the impacts on livelihoods (Annex XVII to EU Regulation 2341/2002).
The federal government of Canada introduced in 2003 a plan of action
to conserve cod stocks off eastern Canada. The plan included closing
three areas to commercial fishing of cod, establishing no trawling zones,
closing a recreational cod fishery and a 40 per cent reduction in capelin
landings, a source of food for cod (Department of Fisheries and Oceans
2003). An economic assistance package to reduce the impact of the closure
on coastal communities was also part of the action plan.
Marine protected areas (MPAs) are one of the tools that may be helpful
in providing a refuge from exploitation, and protecting biodiversity
and essential habitats such as nursery grounds for fish. Studies in
the Florida Keys and Caribbean (Faunce and others 2002), Southern California
(Rogers-Bennett and others 2002) and the Philippines (Alcala and others
2003) have demonstrated that MPAs contribute to the maintenance of fish
stocks. For some species the spillover effect, whereby fish move from
the MPAs into areas beyond, could help improve or at least maintain
the exploited stocks. For example, several of Australia's seamounts
in the Southern Ocean are included in the Heard Island and McDonald
Islands Marine Reserve (the world’s largest MPA) that may help
to conserve the Patagonian toothfish. However, this MPA will not contribute
to conserving the toothfish unless IUU fishing in the region is also
addressed (Meyer and others 2000). MPAs are particularly useful when
they are implemented in combination with other management measures such
as reducing fishing effort.
