MAXIMUM CONSTANT YIELD

maximum constant yield: translation

(MCY)
One way of interpreting maximum sustainable yield; it the maximum constant catch that is sustainable for all probable future levels of stock biomass; see also long-term potential yield. A larger long-term average catch can be achieved from a stock if the catch is adjusted each year to take account of stock increases and decreases due to environmental variability.
