Maximum sustainable yield

In fisheries science, maximum sustainable yield or MSY is the largest long-term average yield/catch that can be taken from a stock of fish without depressing the species' ability to reproduce. A typical MSY is about 80% of the total population biomass of the mature fish capable of reproduction. The maximum sustainable yield is usually higher than the optimum sustainable yield.

A population introduced to a new habitat or with very poor numbers will go through a lag phase of slow growth. Once it reaches a foothold population it will go through a rapid growth rate that will level off once the species reaches carrying capacity. The idea of maximum sutained yeild is to decrease population density to the point of highest growth rate possible. This changes the number of the population, but the new number can be maintained indefinitely, ideally.
