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.
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 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.
Catchers have attributed to the population decline to overfishing, but “overfished” is a technical definition that triggers conservation measures, experts told CNN — it doesn’t actually ...
Overfished refers to the number of fish in the stock. Typically a stock is described as being overfished when current biomass of a stock is lower than what is required to support the maximum sustainable yield. Overfishing describes the rate of removal from a stock and can be categorized as two different types: recruitment and economic ...
The Atlantic fishery abruptly collapsed in 1993, following overfishing since the late-1950s, and an earlier partial collapse in the 1970s. [1] It is expected to recover to historical, sustainable levels by 2030. [2] In 1992, Northern Cod populations fell to 1% of historical levels, due in large part to decades of overfishing. [3]
Between 1949 and 1955, the U.S. maneuvered to have MSY declared the goal of international fisheries management (Johnson 2007). The international MSY treaty that was eventually adopted in 1955 gave foreign fleets the right to fish off any coast. Nations that wanted to exclude foreign boats had to first prove that its fish were overfished. [9]
