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 each ...
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]
Seaspiracy (/ siːˈspɪrəsi /) is a 2021 documentary film about the environmental impact of fishing directed by and starring Ali Tabrizi, a British filmmaker. [1] The film examines human impacts on marine life and advocates for ending fish consumption. The film explores environmental issues affecting oceans, including plastic pollution, ghost ...
There are many effects of climate change on oceans. One of the main ones is an increase in ocean temperatures. More frequent marine heatwaves are linked to this. The rising temperature contributes to a rise in sea levels due to melting ice sheets. Other effects on oceans include sea ice decline, reducing pH values and oxygen levels, as well as ...
Rather than metrics of megatonnage of harvest, or average size of fish, [7] metrics of the residuum with high variation in the countable population due to sampling error, and dynamic environmental factors such as ocean temperature combined to make it difficult to discern the effects of exploitation to an inexpert regulator.

Marine life. Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is ...
Daniel Pauly has suggested a framework for the ecological impacts fishing down can have on marine ecosystems. The framework distinguishes three phases: [23] Pristine – the first phase. Pristine environments are the states ocean ecosystem were in before fishing made strong impacts. Some outlier areas of the South Pacific may still be pristine.
