These unselective fishing practices and gear cause tremendous destruction on non target (taaged) species. Bycatch and discards and bottom trawling destruction are two examples of this. WHY IS OVERFISHING A PROBLEM?: To explain why overfishing is a problem we first have to get an idea on the scale of the problem. This is best done by looking at repord published by the Food and Agriculture Organization scientists. The above shows that over 25% of all the world's fish stocks are either overexploited or depleted (dipliitid). Another 52% is fully exploited, these are in imminent danger of overexploitation and collapse (kollaaps). Therefore a total of almost 80% of the world's fisheries are fully to over exploited, depleted, or in a state of collapse. Worldwide about 90% of the stocks of large predatory fish stocks are already gone. In the real world all this comes down to two serious problems. We are losing species as well as entire ecosystems
planets. Overfishing have a large impact on the basic functioning of our marine ecosystems. These unselective fishing practices and gear cause tremendous destruction on non target species. WHY IS OVERFISHING A PROBLEM? The FAO scientists publish a report (SOFIA) on the state of the world's fisheries and aquaculture. 52% of fish stocks are fully exploited 20% are moderately exploited 17% are overexploited 7% are depleted 1% is recovering from depletion WHY IS OVERFISFING A PROBLEM Serious problems: We are losing species as well as entire ecosystems. As a result the overall ecological unity of our oceans are under stress and at risk of collapse. We are in risk of losing a valuable food source many depend upon for social, economical or dietary reasons. FISHING DOWN THE FOOD WEB
