Which of these outcomes is the main goal of maximum sustainable yield (msy) management? a. to determine what is best for the ecosystem as a whole b. to manage using trial and error c. to account for all the complexities in a stable population d. to determine how many individuals can be taken without making a population unstable

The main goal of maximum sustainable yield (MSY) management is.
