Willi,

I have tried my best but can not satisfy your question for because it
is too nebulous to be taken serious. I've tried as politely as I can
to show you why. I've given you all the data you need to extrapolate
my essential points. I gave you a study that shows the ultimate
control a set of circumstances that could occur naturally in a myriad
of situations of 'self-sustaining' populations.

I've asked you know for the study you report to have many of, because
I want to see how you have defined the following real world
constraints that can not be ignored in your gross oversimplification
of the basic fisheries management equation. Honestly, if that last
study wasn't conclusive, I'm not sure what would be.

I'm not being flippant in the least.



The study you cited is based on the aquaculture of shrimp and fish. You
can't use a study conducted in the closed, man made system of an
aquaculture environment containing a fixed population of age specific
animals and extrapolate the results to the dynamic system of a stream or
river with a self sustaining trout population.
