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]
Overfishing of sharks has increased as the global demand has skyrocketed in recent years. Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth.
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.
Their role keeps the environment healthy because "they usually go after the sick, weak and slower fish populations." Due to shark overfishing in many areas in the world sharks are going missing or endangered. [31] In 2013, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) listed the vulnerability of sharks.

The 2007 film Sharkwater documents ways in which sharks are being hunted to extinction. [15] In 2009, the IUCN Shark Specialist Group reported on the conservation status of pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by high-seas fisheries were threatened with extinction. [16] [17] [18]
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.
