Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
Oceana is dedicated to combating the numerous threats to the world's oceans that climate change imposes. Its main focus has been the acidification of the ocean , which threatens marine life, especially shellfish and coral that are necessary to many marine ecosystems, and, consequently, sources of seafood.

Sustainability can mean different things to different people. Some may view sustainable fishing to be catching very little in order for fish populations to return to their historical levels (represented by the upper left green area), while others consider sustainability to be the maximum amount of fish we can catch without depleting stocks any further (red dot).
Overfishing of sharks has increased as the global demand has skyrocketed in recent years. Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth.
Ray Hilborn stated that the unsustainable nature of fisheries can be characterized by three aspects: . Inconsistent long-term yield refers to the imbalance in nature when fishing is practiced improperly, which results in the inability to capture the maximum sustainable yield at a regular and predictable rate.
The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.
The book provides details about overfishing in many of the world's critical ocean habitats, such as the New England fishing grounds, west African coastlines, the European North Atlantic fishing grounds, and the ocean around Japan. [3] The book concludes with suggestions on how the nations of the world could engage in sustainable ocean fishing. [3]
