Theme: COASTAL AND MARINE AREAS Issue: Unsustainable use of living marine resources
Indicator: World fisheries stocks and marine capture
Over the last decades, there has been continuing
exploitation and depletion of fisheries stocks.
Undeveloped fish reserves have disappeared
altogether since the mid-1980s. During the last
decades, there has been a continued decline in fish
resources in the 'developing' phase, and an increase
of those in the depleted or over-exploited ('senescent')
phase, somewhat offset by the emergence of
resources in the 'recovering' phase.
Global harvests from marine fisheries have been
above 80 million tonnes per year since the latter half
of the 1980s, with peaks of 87 million tonnes in
1997 and 2000.
Since then, the total world catch
of marine fish, crustaceans and molluscs has
declined, with a reported total quantity of about
81 million tonnes for 2003, the latest year for
which comprehensive data are available. The
decrease is mostly related to declines in fishing
zones in the Southeast and Northwest Pacific oceans
