Document Summary

Fao: food & agriculture organization of the united nations. Great amount of fish consumed, many jobs created due to this and especially important for developing countries regarding traded commodities. Continental shelves are highly productive, and only takes less than 7% of surface area of the planet (those shallower than 200 m). Shelves are productive and necessary: they generate the biological production supporting over 90% of global fish catches. The proportion of overfishing is increasing over time.

All species we fish today will collapse by 2048. Effect of aquaculture with world fisheries: aquaculture relieve pressure on wild stocks, but it has its own environmental problems. Ecological links between aquaculture and wild fish stocks: need for fish meal: aquaculture operations use up more fish flesh that people can consume than they produce through fishing the fish humans want. This is a pressure on wild fish populations.
