Examples of overfishing in the following topics:
-
- Overfishing leads to fishery extinctions, loss of a food source, and affects many other species in ways that may be impossible to predict.
- Overfishing is the harvest of an aquatic population to a level that is too low for that population to replenish itself.
- Resource depletion, low biological growth rates, and critically low biomass levels result from overfishing.
- For example, overfishing of sharks has disrupted entire marine ecosystems.
- In addition to eliminating major food sources, overfishing is a threat to aquatic biodiversity.
-
- Adding to the extinction list, the Japanese sea lion, which inhabited a broad area around Japan and the coast of Korea, became extinct in the 1950s due to overfishing.
- The list is not complete, but it describes 380 extinct species of vertebrates after 1500 AD, 86 of which were made extinct by over-hunting or overfishing.
-
- For example, most fisheries are managed as a common resource even when the fishing territory lies within a country's territorial waters; because of this, fishers have very little motivation to limit their harvesting, and in fact technology gives fishers the ability to overfish.
