  2. Maximum sustainable yield - Wikipedia

    en.wikipedia.org/wiki/Maximum_sustainable_yield

    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).

  3. Gordon-Schaefer model - Wikipedia

    en.wikipedia.org/wiki/Gordon-Schaefer_Model

    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.

  4. Optimal rotation age - Wikipedia

    en.wikipedia.org/wiki/Optimal_rotation_age

    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 future uses”.

  5. Sustainable yield in fisheries - Wikipedia

    en.wikipedia.org/wiki/Sustainable_yield_in_fisheries

    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.

  6. Beverton–Holt model - Wikipedia

    en.wikipedia.org/wiki/Beverton–Holt_model

    The Beverton–Holt model is a classic discrete-time population model which gives the expected number n t+1 (or density) of individuals in generation t + 1 as a function of the number of individuals in the previous generation,

  7. Optimum sustainable yield - Wikipedia

    en.wikipedia.org/wiki/Optimum_sustainable_yield

    It usually corresponds to an effort level lower than that of maximum sustainable yield. In environmental science , optimum sustainable yield is the largest economical yield of a renewable resource achievable over a long time period without decreasing the ability of the population or its environment to support the continuation of this level of ...

  8. Catch per unit effort - Wikipedia

    en.wikipedia.org/wiki/Catch_Per_Unit_Effort

    In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance.

  9. Formula editor - Wikipedia

    en.wikipedia.org/wiki/Formula_editor

    A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.
