MAXIMUM SUSTAINED YIELD. The maximum number of fish from a stock or management unit that can be harvested on a sustained basis, measured as the number of fish that would enter freshwater to spawn in the absence of fishing after accounting for natural mortality.
Maximum Sustainable Yield. (King, 1995). The largest annual catch that may be taken from a stock continuously without affecting the catch of future years; a constant long-term MSY is not a reality in most fisheries, where stock sizes vary with the strength of year classes moving through the fishery.
maximum sustainable yield. The maximum number of a food or game population that can be harvested without harming the population's ability to grow back.
Maximum sustainable yield. can be defined in various ways, but originated from surplus-production models as the maximum catch that can be removed from a stock over an indefinite period without affecting sustainability. MSY defined in this way makes no allowance for environmental variability, and studies have demonstrated that fishing at the level of MSY is often not sustainable (cf. longterm potential yield).
maximum sustainable yield. the maximum quantity of a natural resource that can be harvested annually without depleting the resource stock or population.
Maximum sustainable yield. The highest theoretical equilibrium yield that can be continuously taken (on average) from a stock under existing (average) environmental conditions without affecting significantly the reproduction process.
Maximum sustainable yield. The highest average yield over time that does not result in a continuing reduction in stock abundance. Determination of MSY must take into account fluctuations in abundance and environmental variability.
See maximum sustainable yield.
Maximum Sustainable Yield. The largest average catch that can be taken continually (sustained) from a stock under average environmental conditions. This is often used as a management goal.
Maximum sustainable yield. The maximum crop or yield that can be removed repeatedly from a population without driving it towards extinction.
maximum sustainable yield. the greatest number of fish that can be taken without reducing the number of individuals necessary to propagate the species.
Maximum Sustainable Yield - the largest long-term average catch or yield that can be taken from a stock or stock complex under prevailing ecological and environmental conditions.
