According to Food and Agriculture Organization (FAO) statistics the total fish production in the world in 2001 was 130 million tonnes. In addition to the commercial catches, 37.9 million tonnes were produced in aquaculture plants.In the 1990s and 2000s it has become increasingly evident that industrial fishing has severely depleted stocks of certain types of ocean fish, such as cod.
