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.
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 ...
In 2024 a study [147] was released, dedicated to the impact of fishing and non fishing ships on the coastal waters of the ocean when 75% of the industrial activity occur. According to the study: "A third of fish stocks are operated beyond biologically sustainable levels and an estimated 30–50% of critical marine habitats have been lost owing ...

The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs.
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 concept of maximum sustainable yield (MSY) has been used in fisheries science and fisheries management for more than a century. Originally developed and popularized by Fedor Baranov early in the 1900s as the "theory of fishing," it is often credited with laying the foundation for the modern understanding of the population dynamics of fisheries.

The overfishing of these large fisheries destroys the marine environment and threatens the livelihood of billions who depend on fish as protein or as a source of income for catching and selling. [21] According to the World Wildlife Fund, illegal, unreported, and unregulated fishing is a major factor in overfishing.
