Southeastern Louisiana's disappearing wetlands have a broad impact ranging from cultural to economic. Commercial fishing in Louisiana accounts for more than 300 million dollars of the state's economy. More than 70% of that amount stems from species such as shrimp, oysters and blue crabs that count on the coastal wetlands as a nursery for their ...
In 1998 in a book, Bell argued [38] that the collapse of the fishery and the failure of the Listing process was ultimately facilitated by secrecy (as long ago in the defense science context observed by the venerable C. P. Snow [39] and recently cast as "government information control" in the fishery context [40]) and the lack of a code of ...
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.
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]

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.

The collapse can happen when the ecosystem's distribution decreases below a minimal sustainable size, or when key biotic processes and features disappear due to environmental degradation or disruption of biotic interactions. These different pathways to collapse can be used as criteria for estimating the risk of ecosystem collapse.
