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.
Concerned about declining fish catches since 1980, Oceana is committed to combating overfishing and restoring the world's fisheries. It mainly focuses on legislation for scientific based catch limits, which have led to dramatic recoveries of depleted fisheries in the recent past. It also opposes fishing subsidies, which it argues are (in their ...
Overfishing is occurring in one third of world fish stocks, according to a 2018 report by the Food and Agriculture Organization of the United Nations. [9] In addition, industry observers believe illegal, unreported and unregulated fishing occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. [10]
The UN's Food and Agriculture Organization (FAO) released their biennial State of World Fisheries and Aquaculture in 2018 [58] noting that capture fishery production has remained constant for the last two decades but unsustainable overfishing has increased to 33% of the world's fisheries. They also noted that aquaculture, the production of ...
Ray Hilborn stated that the unsustainable nature of fisheries can be characterized by three aspects: . Inconsistent long-term yield refers to the imbalance in nature when fishing is practiced improperly, which results in the inability to capture the maximum sustainable yield at a regular and predictable rate.
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.
For example, "85 percent of the world’s fisheries are fished at or beyond their maximum sustainable limit." [2] Considering the rising global population and the pressure that it has, and will continue to exert on the Earth's resources, a more sustainable method of fishing is necessary if humans wish to utilize its natural abundance.
