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.
While teaching at Berkeley, Harsanyi did extensive research in game theory. Harold Kuhn, who had been John von Neumann's student in Princeton and already had games theory publications encouraged him in this. The work for which he won the 1994 Nobel Prize in economics was a series of articles published in 1967 and 1968 which established what has ...
[5] [6] Canada and NAFO had tracked about 50 violations of boats crossing the 200 nautical mile EEZ limit to fish illegally within Canadian waters and recorded the use of illegal gear and overfishing outside Canadian waters. There was a growing concern in Canada that the turbot stock, like the Northern cod in 1992, was threatened by collapse.
Separately, game theory has played a role in online algorithms; in particular, the k-server problem, which has in the past been referred to as games with moving costs and request-answer games. [125] Yao's principle is a game-theoretic technique for proving lower bounds on the computational complexity of randomized algorithms , especially online ...
Evolutionary game theory differs from classical game theory in focusing more on the dynamics of strategy change. [2] This is influenced by the frequency of the competing strategies in the population. [3] Evolutionary game theory has helped to explain the basis of altruistic behaviours in Darwinian evolution.
Iceland made threats it would withdraw from NATO, which would have forfeited NATO's access to most of the GIUK gap, a critical anti-submarine warfare chokepoint during the Cold War. In a NATO-brokered agreement in 1976, the United Kingdom accepted Iceland's establishment of a 12-nautical-mile (22 km) exclusive zone around its shores and a 200 ...

Cod fishing on the Newfoundland Banks. Cod fishing in Newfoundland was carried out at a subsistence level for centuries, but large scale fishing began shortly after the European arrival in 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 1992.
