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 traps are the cause of countless environmental issues, including overfishing, energy "brownout" and "blackout" power outages during periods of extreme temperatures, the overgrazing of cattle on the Sahelian Desert, the destruction of the rainforest by logging interests and agriculture, and, most importantly, climate change.
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 journal Science published a four-year study in November 2006, which predicted that, at prevailing trends, the world would run out of wild-caught seafood in 2048. [55] The scientists stated that the decline was a result of overfishing , pollution and other environmental factors that were reducing the population of fisheries at the same time ...
Ray Hilborn stated that the unsustainable nature of fisheries can be characterized by three aspects: . Inconsistent long-term yield refers to the imbalance in nature when fishing is practiced improperly, which results in the inability to capture the maximum sustainable yield at a regular and predictable rate.
The Atlantic fishery abruptly collapsed in 1993 after overfishing from 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, in large part from decades of overfishing. [3]
A 2019 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report found that overfishing is the main driver of mass species extinction in oceans. [142] [143] Overfishing has reduced fish and marine mammal biomass by 60% since the 1800s. [144] It is currently pushing over one-third of sharks and rays toward ...
