[¦mak·sə·məm sə¦stān·ə·bul ′yēld]
(oceanography)
In fishery management, the highest average fishing level over time that does not reduce a stock's abundance in balance with the stock's reproductive and growth capacities under a given set of environmental conditions.
A level of fishing that, if approached, should signal caution rather than increased fishing.
