The maximum sustainable yield is the largest yield that can be taken from a population at equilibrium. In figure 3, if H {\displaystyle H} is higher than H 2 {\displaystyle H_{2}} , the harvesting would exceed the population's capacity to replace itself at any population size ( H 3 {\displaystyle H_{3}} in figure 3).
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.
The maximum sustainable yield is usually higher than the optimum sustainable yield. This logistic model of growth is produced by a population introduced to a new habitat or with very poor numbers going through a lag phase of slow growth at first. Once it reaches a foothold population it will go through a rapid growth rate that will start to ...
Graph of mean annual increment. Biologists use the concept of maximum sustainable yield (MSY) or mean annual increment (MAI), to determine the optimal harvest age of timber. MSY can be defined as “the largest yield that can be harvested which does not deplete the resource (timber) irreparably and which leaves the resource in good shape for ...
The sector has had to deal with an inverted yield curve (when short-term rates are higher than longer-term rates) for two years, so the return of a more normal yield curve (when yields on long ...
Sustainability Index = Emergy Yield Ratio / Environmental Loading Ratio = EYR / ELR NOTE: The numerator is called "emergy" and is spelled with an "m". It is an abbreviation of the term, "embodied energy". The numerator is NOT "energy yield ratio", which is a different concept. [15]
