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.
The book provides details about overfishing in many of the world's critical ocean habitats, such as the New England fishing grounds, west African coastlines, the European North Atlantic fishing grounds, and the ocean around Japan. [3] The book concludes with suggestions on how the nations of the world could engage in sustainable ocean fishing. [3]
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]
When compared to more developed regions in the world, under-developed regions, on average, account for three-fold greater harvest rates. [ 37 ] This shows an obstacle for mitigating unsustainable fishing methods, which is influenced by a social-ecological trade off . [ 38 ]
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.
[11] [25] [24] However, although it did play a part in causing the crash of the population, recent times and research have found that overfishing was also a large cause of the crisis. [ 31 ] [ 32 ] [ 23 ] [ 33 ] Before the collapse, the fishing quota of about 9.5 million tons set by both the Peruvian government and recommended by scientists was ...

The Atlantic fishery abruptly collapsed in 1993, following overfishing since the late-1950s, and an earlier partial collapse in the 1970s. [1] It is expected to recover to historical, sustainable levels by 2030. [2] In 1992, Northern Cod populations fell to 1% of historical levels, due in large part to decades of overfishing. [3]
