Overfishing

Harper, S. Distributional impacts of fisheries subsidies and their reform: case studies from Senegal and Vietnam. IIED, London. Teh, L. Economic and social benefits of fisheries rebuilding: six Canadian case studies.

Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area. In a Food and Agriculture Organization of the United Nations report, the FAO estimates that one-third of world fish stocks were overfished by Overfishing can occur in water bodies of any sizes, such as ponds, rivers, lakes or oceans, and can result in resource depletion , reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation , where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks , has led to the upset of entire marine ecosystems. The ability of a fishery to recover from overfishing depends on whether the ecosystem 's conditions are suitable for the recovery. Dramatic changes in species composition can result in an ecosystem shift , where other equilibrium energy flows involve species compositions different from those that had been present before the depletion of the original fish stock.
