A fishery is socially sustainable if the fishery ecosystem maintains the ability to deliver products the society can use. Major species shifts within the ecosystem could be acceptable as long as the flow of such products continues. [2] Humans have been operating such regimes for thousands of years, transforming many ecosystems, depleting or ...
Sustainable seafood is from either fished or farmed sources that can maintain or increase production in the future without jeopardizing the ecosystems from which it was acquired. The sustainable seafood movement has gained momentum as more people become aware of both overfishing and environmentally destructive fishing methods. Fish farming can ...
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 National Marine Fisheries Service (NMFS), informally known as NOAA Fisheries, is a United States federal agency within the U.S. Department of Commerce 's National Oceanic and Atmospheric Administration (NOAA) that is responsible for the stewardship of U.S. national marine resources. It conserves and manages fisheries to promote ...
These approaches are applied to six areas of focused effort – managing fishing capacity, mitigating bycatch, eradicating illegal, unreported and unregulated (IUU) fishing, expanding data support, advancing industry performance through monitoring, control and surveillance (MCS) and improving overall tuna stock health.
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.
Climate change is modifying fish distributions [ 6] and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. [ 7] The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector.
Gordon-Schaefer model. (Redirected from Gordon-Schaefer Model) The Gordon-Schaefer model is a bioeconomic model applied in the fishing industry. It may be used to compute the maximum sustainable yield. It takes account of biological growth rates, carrying capacity, and total and marginal costs and revenues. [1][2]
