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 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.
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]
Three ways of defining a sustainable fishery exist: 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 ...

The goal of fisheries management is to produce sustainable biological, environmental and socioeconomic benefits from renewable aquatic resources. Wild fisheries are classified as renewable when the organisms of interest (e.g., fish , shellfish , amphibians , reptiles and marine mammals ) produce an annual biological surplus that with judicious ...
