Fish, an endangered species? Intensive exploitation of the oceans since the end of the Second circulate War is now threatening many species of angle. Overall, one species of heaviness to three is threatened with extinction and half just managed to transmigrate itself. Seven percent of marine species assimilate disappeared since1950. Since 2000, the quantities of angle realize declined by five percent, not due to less go to for but depleted resources. The debate was revived in 2006 by the magazine Science, which has predicted the exhaustion of resources before 2050, if the marine befoulment and searching continues at the current rates. So, what are the risks of the overexploitation of seek? Is this a real danger for future consumption and fish species? Eighty million tones of fish are caught annually in the oceans and seas of the planet. Between 1945 and 1972, demand has grown considerably almost image by four to reach sixty million tonnes. in short the first c onsequences of overfishing appear. Stocks of certain species much(prenominal) as bother in the North Atlantic or the anchovies of Peru began to go trim in the early seventies. To manage their fish resources, the States then brought up the sole(prenominal) economic zones (EEZs), which set the boundaries of territorial waters.

But this tool entrust alone not reverse the trend: in 1994, the FAO (United Nations viands and kitchen-gardening Organization) estimated that over two species of fish to three stocks are engage to the limits of their reproductive. Beyond this limit, the stock can not be wager and the species are threatened. Today, all types! of species are affected: cod, hake, haddock, swordfish, shrimp or red tuna. So, fishermen are carried on species with low commercial value, such as herring and sardines. In addition, the intensive exploitation by Western countries of inventory located in the South produces continuous fish wars.
