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.
Social factors, through social conception of human well-being, can potentially improve the implementation of fisheries regulation and governance. [42] This remains a difficult concept in developing fishery regions, such as Caribbean coral reef fisheries, where managing and regulating parrotfish ( Sparisoma viride ) resulted in an initial ...
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.
Overfishing can be sustainable. [dubious – discuss] According to Hilborn, overfishing can be "a misallocation of societies' resources", but it does not necessarily threaten conservation or sustainability". [2] Overfishing is traditionally defined as harvesting so many fish that the yield is less than it would be if fishing were reduced. [2]
The African penguin joins the list of species said to be threatened by climate change - and overfishing. Researchers from the UK and South Africa say penguin numbers in the Benguela upwelling ...
The problem of overfishing are as follows: the catches of wild fish have peaked and are now in decline, rational fishery management is the exception rather than the rule, the most valuable fish is trawled to the point of extinction, the developed world is stealing from both the developing world and the future generations, and fish farming, the ...
