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.
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called ...
Illegal, Unreported, and Unregulated (IUU) Fishing poses a global challenge and has significant economic and environmental repercussions. [5] The impact of IUU fishing includes economic losses, job losses, scarcity, price distortion, food insecurity and unfair competition, [6] together with the depletion of fish populations and damages to the marine habitat.

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 ...
Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [ 2] ocean acidification [ 3] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in water temperature, water flow, and fish habitat loss. [ 4] These effects vary in the context of each ...
e. 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.
Unsustainable fishing methods vary in scale, ranging from commercial-grade equipment, such as bottom trawling, to consumer-grade equipment, such as fishing rods and nets. [3] A combination of these fishing methods and an increase in fishing pressures through sociological practices such as over-exploitation and overfishing, that make these ...
