Fisheries
A fishery can be defined as an entity involved in the raising of fish through aquaculture or the harvesting of wild fish in oceans, seas and freshwater. Humans have relied on aquatic resources for sustenance and survival for centuries yet with the advent of improved fishing vessels, techniques, tools, and equipment as well as technology coupled with growing demands for resources, the rate of exploitation has reached unprecedented rates raising fears about the inevitable collapse of aquatic ecosystems. Rapacious techniques such as bottom trawling or use of large nets modify marine ecosystems by physically altering habitats, reducing biodiversity and disrupting food chains. There is also a growing concern that fisheries have reached their global maximum potential as many valuable fish stocks have already been depleted, leading to the exploitation of less valuable fish.
