Document Summary
In addition to fresh water and wetland ecosystem services, aquatic ecosystems around the planet provide a huge diversity of fisheries resources. World commercial fisheries harvests in 2008 142 million metric tons (mmt) About 110 mmt was made up of finfishes. The other 32 mmt comprised of mostly of crustaceans and mollusks. The commercial sector includes food fisheries as well as industrial fisheries. Freshwater and marine recreational fishing important in many countries. Food fish operations = harvested for direct consumption. Industrial fishery harvested not for direct consumption, used for oil for chicken feed. Many commercially and recreationally exploited fish and invertebrate stocks declined during the 19th and 20th centuries. Recreational fishing = if you can sell what u catch, let them go or consume them yourself. In addition, many non-exploited aquatic species also declined in abundance from habitat loss and degradation. Fisheries are an excellent example of a renewable resource. Because they reproduce: recreational fishing is based on numbers.
