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.
Canned tuna is readily available to the general public. However, most canned tuna is fished unsustainably. The first problem is bycatch. Purse seins up to 80 miles long sweep the oceans for tuna, but catch everything else in the area, including sharks, dolphins, and other fish. Second, little is being done to restrict the tuna fleet.
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.

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 bluefin tuna is a vulnerable species, whose future is at risk due to overfishing — but it’s still very good business. One at-risk bluefin tuna sells for more than $600,000 Skip to main content
"A 130-pound woman can eat almost two six-ounce cans of light tuna a week and stay within the EPA-recommended safe zone for mercury," said Wright. Light tuna is recommended to limit the amount of ...
The organisation has been strongly criticised by scientists for its repeated failure to conserve the sustainability of the tuna fishery by consistently supporting over-fishing – an internal review branded ICCAT's policies on the eastern Atlantic bluefin tuna fishery a "travesty of fisheries management", and an "international disgrace".

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.
