I think you're suggesting that rather than choosing the MSY "point", you're talking about using a range of points to define MSY?

I think you're also suggesting that foregone opportunity would cease to be an issue because we could harvest at the lowest end of the "MSY range", but not be under-harvesting because we were still escaping below the highest end of the range?
I think you summed up the jist of the concept I was trying to get across very nicely, Todd. A range of points is indeed capable of producing MSY.... I just have this suspicion that fish managers currently prosecute the fishery based on achieveing the lowest possible MSY escapement .

I see your point about forgone opportunity as it relates to this concept. The other avenue of redefining "yield" is a much better one to pursue.

However, I still believe issues of under- or over-harvest are better addressed by managing for an escapement range as opposed to an escapement point. That's how Alaskans manage fish runs in their most contentious and fully-allocated fisheries.
