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.
A study conducted in the Glover's Reef Marine Reserve, Belize, between 2004-2010 and 2011-2017, found that the mortality rates for most species were much higher than the natural mortality rate. [26] This is a result of over-fishing with the main gears being used in those regions consisting of spears and fishing rods. [ 26 ]
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
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]
Former President Trump released a campaign proposal Friday to punish human traffickers with the death penalty, his latest tough-on-crime policy unveiled as part of his 2024 White House bid.
Since its introduction, Homo sapiens (the human species) have been killing off entire species either directly (such as through hunting) or indirectly (such as by destroying habitats), causing the extinction of species at an alarming rate. Humans are the main cause of the current mass extinction, called the Holocene extinction, driving ...
