Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 643 endangered fish species. [1] Of all evaluated fish species, 4.2% are listed as endangered. The IUCN also lists ten fish subspecies as endangered.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of July 2017, the International Union for Conservation of Nature (IUCN) listed 1,000 critically endangered fish species, including 87 which are tagged as possibly extinct. [1] [2] Of all evaluated fish species, 3.0% are listed as critically endangered ...
The five stages of their development were originally thought to be different species. They are critically endangered due to hydroelectric dams, overfishing by fisheries on coasts for human consumption, and parasites. [4] [5] [6] [7]
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.
See: List of endangered fishes, List of critically endangered fishes. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN. Additionally 3191 fish species (21% of those evaluated) are listed as data deficient , meaning there is insufficient information for a full assessment of ...
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.
