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 maximum sustainable yield is usually higher than the optimum sustainable yield and maximum economic yield. MSY is extensively used for fisheries management . Unlike the logistic ( Schaefer ) model, [ 1 ] MSY has been refined in most modern fisheries models and occurs at around 30% of the unexploited population size.
In population ecology and economics, the maximum sustainable yield or MSY is, theoretically, the largest catch that can be taken from a fishery stock over an indefinite period. [8] [9] Under the assumption of logistic growth, the MSY will be exactly at half the carrying capacity of a species, as this is the stage at when population growth is ...
The book thus ties fisheries management inseparably with Cold War politics. [1] In particular, Finley traces the development of the concept of maximum sustainable yield (MSY), arguing that MSY had no scientific basis and thus was a political and economic construct more than a scientific one. The "model did not represent the codification of ...
An open entry policy usually results in too many fishermen so profits are barely higher than opportunity costs. See economic rent. Maximum sustainable yield (MSY) – the maximum catch that can be taken from a species' stock over an indefinite period. Under the assumption of logistic growth, the MSY will be exactly at half the carrying capacity ...
