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 ...
Overfishing of high trophic fish like tuna can result in them being replaced by low trophic organisms, like jellyfish See also: Overfishing and Environmental impact of fishing Overfishing is occurring in one third of world fish stocks, according to a 2018 report by the Food and Agriculture Organization of the United Nations.

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 Atlantic bluefin tuna has been the foundation of one of the world's most lucrative commercial fisheries. Medium-sized and large individuals are heavily targeted for the Japanese raw-fish market, where all bluefin species are highly prized for sushi and sashimi. This commercial importance has led to severe overfishing.
Tuna and tuna-like fishes are highly migratory, and stocks cross numerous international boundaries.ICCAT is involved in management of 30 species, including the Atlantic bluefin (Thunnus thynnus thynnus), yellowfin (T. albacares), albacore (T. alalunga) and bigeye tuna (T. obesus); from the billfishes, swordfish (Xiphias gladius), white marlin (Tetrapturus albidus), blue marlin (Makaira ...
The overfishing of these large fisheries destroys the marine environment and threatens the livelihood of billions who depend on fish as protein or as a source of income for catching and selling. [21] According to the World Wildlife Fund, illegal, unreported, and unregulated fishing is a major factor in overfishing.
