The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. [ 1 ] These issues are part of marine conservation, and are addressed in fisheries science programs.
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 ...
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 ]
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 occur in water bodies of ...
A fishery is socially sustainable if the fishery ecosystem maintains the ability to deliver products the society can use. Major species shifts within the ecosystem could be acceptable as long as the flow of such products continues. [2] Humans have been operating such regimes for thousands of years, transforming many ecosystems, depleting or ...
Scuba diving tourism is a growth industry, and it is necessary to consider environmental sustainability, as the expanding impact of divers can adversely affect the marine environment in several ways, and the impact also depends on the specific environment. Tropical coral reefs are more easily damaged by poor diving skills than some temperate ...
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 ...
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate which is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting ...
