maximum sustainable yield

maximum sustainable yield
the average or maximum catch that can be removed under existing environmental conditions over an indefinite period without causing the stock to be depleted, assuming that removals and natural mortality are balanced by stable recruitment and growth. In fisheries, this method was an effort to take all the fish that the fishery could supply on a continuous basis. However it did not work out on a practical basis as good years were mixed with bad years (more or less production than the simple theories predicted) and prediction of the maximum sustainable yield was difficult. Overestimates or a series of bad years will cause a fall in biomass. The fishery will have to be reduced while the stock recovers. More conservative methods are now used (see optimum sustainable yield). Abbreviated as MSY or Ys. Also called maximum equilibrium catch, maximum sustained yield, sustainable catch
