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.
The maximum sustainable yield (MSY) is the largest amount of biomass that can be collected annually for indefinite periods. MSY assesses the productive capacity of the fishery, rather than demand or economic costs. MSY output may be greater or less than monopolistic or competitive output.

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.

MSY is extensively used for fisheries management. [10] [11] Unlike the logistic (Schaefer) model, MSY in most modern fisheries models occurs at around 30-40% of the unexploited population size. [12] This fraction differs among populations depending on the life history of the species and the age-specific selectivity of the fishing method.
The Magnuson-Stevens Act requires Councils to prepare Fishery Management Plans for overfished fisheries and for other fisheries where regulation will be beneficial according to cost whether its in the present or future. The following factors shall be considered, among others to implement a Fishery Management Plan: [10]
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 ...
Territorial waters and exclusive economic zone of the Philippines. The Philippines is an archipelagic state whose over 7,000 islands [1] with their large coastal population [2]: 2 are surrounded by waters including 2,263,816 square kilometres (874,064 sq mi) of exclusive economic zone and 679,800 square kilometres (262,500 sq mi) of territorial sea, [3]: 1 of which 184,600 square kilometres ...
