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]
Examples of unsustainable fishing methods exist globally and impacts the harvest species, as well as all marine species that coexist or rely on the targeted harvest. [ 19 ] Bottom trawling in Canadian waters have shown the destructive effects of the fishing method.
The sea animal's aquatic ecosystem may also collapse due to the destruction of the food chain. Additionally, ghost fishing is a major threat due to capture fisheries. [16] Ghost fishing occurs when a net, such as a gill net or trawl, is lost or discarded at sea and drifts within the oceans, and can still act to capture marine organisms. [16]
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.
A gyre is a circular ocean current formed by the Earth's wind patterns and the forces created by the rotation of the planet. [33] There are five main ocean gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre. There are significant garbage patches in each of ...
