Some Obscurish facts
#51
90% of all the oceans' large fish have already been removed from the seas, a comprehensive 10 year study by German and Canadian scientists has revealed. The study - see Nature, May 15 - shows that every time industrial fishing has moved into unfitted areas, the biomass of the larger marine predators has been rapidly reduced to less than one tenth its original size. All available fisheries data from around the world was examined: this is fact, not theory. It compared the biomass and composition of large predatory fishes in four continental shelves and nine oceanic systems from the beginning of exploitation to the present.
