Gosh - I sure wish I was a biologist or at least had access to the bulk of the data on spawning escapements, out migrations of smolts and the consequent returning adult numbers.

From what little data I have gathered it seems that adult return numbers are not well correlated with parental spawning escapements. Should that be true then the surplus determined by the MSY system of has a poor probability of actually being correct.

That said, I must say that I get tired of hearing some people put down MSY year after year without offering an alternative. I would ask those who condemn MSY as a management tool to suggest a better method.
