Icelandic, Norwegian, Danish and Canadian combined research results show that the occurence of eatable fish in the Northern Atlantic has decreased by 2/3 since 1950. The populations of cod, haddock, flounder and tuna have decreased by 5/6 since 1900.

The results also show that the draughts have been reduced by 50 per cent since 1950, even though the boats now spend ten times the amount of energy per fish. However, the biggest decrease has come these last 20 years. The researchers state that a decrease in draughts is absolutely necessary, and that 20 per cent of the ocean areas should become non-fishing zones by the year 2020.
