In fisheries terms, maximum sustainable yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions. [22] MSY aims at a balance between too much and too little harvest to keep the population at some intermediate abundance with a maximum replacement rate.
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 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.

Long term constant yield is the idea that undisturbed nature establishes a steady state that changes little over time. Properly done, fishing at up to maximum sustainable yield allows nature to adjust to a new steady state, without compromising future harvests. However, this view is naive, because constancy is not an attribute of marine ...
The amount that is available to be harvested is controlled by the benchmarks MSY and OY. MSY is the maximum sustainable yield and OY is the optimum yield of a stock. The main difference between MSY and OY is that MSY considers only the biology of the fish while the OY considers the economic aspect of the harvest.
The Magnuson-Stevens Act Provisions is necessary to help compliance the requirements of the MSA to end and prevent overfishing, rebuild overfished stocks, and achieve maximum yield [1] NOAA Fisheries stock status of 2015
The issue of over-fishing in the mid-1850s led to a new reference point for fishery management known as the maximum sustainable yield. [14] Sustainable yield in fishery management is defined as the number of fish that can be extracted without reducing the base of fish stock, and the maximum sustainable yield is defined as the number of fish ...
