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 ...
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.
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. [9] In addition, industry observers believe illegal, unreported and unregulated fishing occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. [10]
The profit from their catches is described to be a factor in the continual use of the dangerous practice. [ 24 ] During the period between 2000 and 2001, a field study was conducted in Oman to simulate the catch rate of fishing gear that has been lost in the ocean (ghost fishing), by setting nets at various depths in fishing grounds across ...
Similarly, white tuna, yellowtail, Dover sole and wild-caught salmon were also often substituted for other species. Most of the time, price gouging is the only harm that comes from such mislabeling.
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.
