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 ...

Fish stocks are said to "collapse" if their biomass declines by more than 95 percent of their maximum historical biomass. Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992. [1] Even though fishing has ceased, the cod stocks have failed to recover. [1]
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.

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 ...
Hilborn points out that continuing to exert fishing pressure while production decreases, stock collapses and the fishery fails, is largely "the product of institutional failure". [2] Today over 70% of fish species are either fully exploited, overexploited, depleted, or recovering from depletion.
The commercial and recreational fishing industry have been significantly impacted by the hypoxic zone. [43] In 2021, the low-oxygenated waters caused a mass-kill event of freshwater drum fish species (also known as sheepshead fish). [48] Water from the lake is also used for human drinking. [49]
