ewest, I use the "by gosh and by golly" form of scientific measurement.
Actually, I can do a bit better than that. I've kept pretty good records of what I stocked and then am assuming a 20-40% annual mortality rate. What is harder to work with is that I am still working with many of the fish that were stocked when they were small in the initial stocking. Beyond that, I look at what we are catching and how each species contributes to the over all fishing experience.
A harder part of all of this is just getting the fish at big enough sizes to escape predation.
This might all sound like a lot of work but it's no more than someone with CC or HSB must go through.
