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.
Cod fishing in Newfoundland was carried out at a subsistence level for centuries, but large-scale fishing began shortly after the European discovery of the North American continent in 1492, with the waters being found to be preternaturally plentiful, and ended after intense overfishing with the collapse of the fisheries in the 1990s.
Sustainable fish farming practices do not use dangerous chemicals, hormones, or antibiotics on their fish, which benefits the surrounding marine environment, and the human consumers themselves. In addition to this, sustainable fish farming is able to control what their fish eat: farmers will take care to keep the fish's diet healthy and balanced.
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]
It is favoured by tuna, leading to one of the species' common names – "tuna crab". [1] Other fish known to feed on G. planipes include billfishes, yellowtail amberjack, sharks [9] and Epinephelus analogus. [10] The diets of gray whales, [11] Bryde's whales, [12] blue whales [12] and sea otters [13] all include G. planipes.
Tuna is a species of saltwater fish that is found in all the world's oceans, including the Atlantic, Pacific, and Indian. There are 15 types of tuna globally, Weintraub notes, but in Western ...

For the most recent several decades, the political goals in fisheries management of commercially important species have been rapidly evolving, primarily driven by (1) a recognition of the response of fish and other target animals to changing climate, (2) new technologies for fishing particularly on the high seas, (3) development of competing ...
