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.
The overfishing of these large fisheries destroys the marine environment and threatens the livelihood of billions who depend on fish as protein or as a source of income for catching and selling. [21] According to the World Wildlife Fund, illegal, unreported, and unregulated fishing is a major factor in overfishing.

Without sharks, the ecosystem would be thrown off, triggering changes to the ocean as we know it. Awareness and support of the overfishing problems and the risk of extinction are critical for ...
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.
[10] This program is designed as a long-term research program to study the "possible long-range effects of pollution, overfishing, and man-induced changes of ocean ecosystems" and to conduct the research required to find dumping alternatives and to consider, in cooperation with other federal agencies, the feasibility of regional management ...
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.
Pollution is not easy to fix, because pollution sources are so dispersed, and are built into the economic systems we depend on. The United Nations Environment Programme (UNEP) mapped the impacts of stressors such as climate change, pollution, exotic species, and over-exploitation of resources on the oceans. The report shows at least 75 percent ...
