Now, though, with that kind of disparity, if its real, is even wider than the raw numbers indicate.


That adult equivalent adjustment has been utilized in the past as you indicated. I suspect that it is still utilized at some point but whether these numbers include that factor is unspecified.

With the erosion of WDFW's support for the winter blackmouth fishery that methodology will become less and less important.

Another thing to ponder is the impact of pinniped predation on the survival to maturity graph. Bet it isn't pretty.
