That part was a bit confusing. In the article it made it sound like future browns will be held until they are 10-12 inches then stocked as opposed to the 8 inch variety, but then it mentions a one time stocking of fish of up to 15 inches this year.
I do remember the brook trout thing....guess that didn't work out, but would they have stocked them instead of the brown's if it did....that would have been sweet, but I can't imagine brook trout doing well in the Meramec at all.
I took the additional size of the stocked brown trout as a by product of the parasite issue with the real goal to improve the rearing of rainbow trout. The different stocking times for brown trout seemed geared to helping the red ribbon area and the increased size probably won't hurt.
Should be interesting...it is tough/marginal place for trout, but close to home. Would be nice to see it fish better.
