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.
Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
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]
Oceans activists are calling for tinned tuna to be banned from hospitals, school canteens, care homes and maternity wards after high concentrations of mercury were found in every sample analysed.

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 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 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 ...
