There was an easily definable trigger to open the fishery from the moratorium, and it was a 3 year average YOY index above 8, so there must be a trigger to either start to rachet it back or shut it down.
What I saw in your answer was that we are striving for maintaining a maximum sustainable yeild estimated to be 0.41% and our fishing mortality rate in the bay is F=0.27. Those numbers means nothing to me, but a YOY index average under 8 or trying to maintain a population of spawning age fish at a particular number would make sense to me.
Can you tell me what you response translates to in data that I may be familiar with, if that is even possible?

The 3 year average is not for over all management. The biomass of productive females is the key. If it falls below the level that ASMFC has set. Then heavy restrictions set in. Also if the mortality rate for the bay exceeds F=.27 then restrictions on catch are enacted.
The mortality rate for the bay in 2007 was F=.10.
There is a 2 year lag on data. 2008 data will be available at the end of this summer.
The over all quota for the Chesapeake for 2010 was reduced 6%.
