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 number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said. ... More than 80% of fish stocks are not overfished ...

Fish farms are regulated by laws and management plans, which prevents it from falling prey to the same phenomenon of overfishing, which cripples the fish populations and marine ecosystem as a whole. The basic premise of fish farming is just what it sounds like—to breed and raise fish in enclosed environments, then eventually sell the grown ...
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate that is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...
Overfished refers to the number of fish in the stock. Typically a stock is described as being overfished when current biomass of a stock is lower than what is required to support the maximum sustainable yield. Overfishing describes the rate of removal from a stock and can be categorized as two different types: recruitment and economic ...
NOAA Fisheries has been successful at ending overfishing in U.S. waters, and science-based management has resulted in 47 once-overfished U.S. fish stocks being declared rebuilt. [ 20 ] [ 21 ] In July 2020, NOAA Fisheries published a report showing that the number of U.S. fish stocks subject to overfishing was at an all-time low in 2019—93 ...
A significant factor contributing to the depletion of the cod stocks off Newfoundland's shores was the introduction of equipment and technology that increased landed fish volume. [5] From the 1950s onwards, new technology allowed fishers to trawl a larger area, fish more in-depth, and for a longer time, with the catches peaking in the 1970s and ...
