Ocean fisheries: Global marine resources continue to decline

In spite of action on the part of coastal States, and good progress in some cases, the overall decline in global fisheries continues. The most serious pressures on fisheries resources remain overfishing, pollution and loss of habitats. Policy and management actions to safeguard these resources must focus on countering the overcapacity of fishing fleets and the integration of plans to rebuild marine resources with national political and economic decision-making.

 

Fish is the most important source of animal protein for over one billion people. The population growth in southern countries, the rising demand for fish in industrial nations and increasingly more effective fishing methods strain wild fish stocks beyond biologically safe limits. Despite the worldwide increase in contribution to supplies, fish farming has not truly relieved pressure on the oceans, as the feedstuffs required here in turn widely originate from the ocean.

 

The seas of the European Union are especially overfished when compared globally. For decades the fisheries policy has not been successful in counteracting this with effective measures. Only in 2013, with the planned reform of the „Common Fisheries Policy” (CFP), will the European Union provide the opportunity to shift its focus towards fishing which is both environmentally sound and economically sustainable in the long-term, even beyond European waters, as the fishing fleets also fish off the shores of West Africa and in the Southern Ocean, exporting the overfishing problem.

 

In contrast to highly-equipped fishing fleets, artisanal fishers in many regions of the world go out with the simplest of fishing equipment and concentrate on coastal and protected waters, on coral reefs or mangroves. Even here, without effective fishing management with the participation of the local people directly dependent on fish and seafood, sustainable fishing cannot be achieved.

 

The globalised market for fish and other seafood is one of the economic factors contributing to overfishing of the oceans. Each individual can act against this and use their leverage through sensible purchasing behaviour. Deciding on products from sustainable fisheries will change the range of fish and, ultimately, the fisheries policy.
