West Africa has a long tradition of fishing, via both local and distant water fleets …

This graph illustrates the reach of Ghanaianfishers during the period up to 1959

Page 3: State of the Northwest African marine fisheries resources Press briefing to accompany the International Symposium on Marine fisheries, ecosystems and societies

The fish wealth of West Africa has also attracted distant water fleets from other continents …

… and these have increased tremendously over the years …

… finally reaching the present, staggering

levels.

What is the impact of all this fishing on the resource base?

• We show this impact for the countries of the Northwest African sub-region using a methodology previously applied to the North Atlantic and which is documented at www.fisheries.ubc.ca;

• This methodology is based on maps of catch data and twenty ecosystem models, as presented at the Dakar Symposium by Villy Christensen, Reg Watson, and other members of the Sea Around Us Project.

Page 10: State of the Northwest African marine fisheries resources Press briefing to accompany the International Symposium on Marine fisheries, ecosystems and societies

The reason for this is fishing intensity, which was low in 1950 …

… but increased tremendously over time …

… finally reaching the very high present levels of fishing intensity.

Conclusions

• The fish resources and ecosystems of Northwest Africa are as depleted as those of the North Atlantic and the fisheries are not sustainable;

• Surplus fishing vessels shifted from the ‘North’ to the ‘South’ will not increase catches;

• Rather, they will continue to undermine the development and food security of the West African countries.
