Don, as usual, despite your impression, on a basic, fundamental level, we agree.
For invasives, you say puhtata, I say poe-tay-toe! (Anyone catch the LOTR reference there?) Therefore, by your logic, Brown and Brook trout are invasives as well, as you well know. Lots of native fish in Red Deer / Clearwater - North Sask water basins before the Europeans showed up. The minnows, whitefish, bull trout, suckers, walleye and pike weren't stocked, to my knowledge (by all means clarify the facts if I am wrong...). Funny how you'll tolerate brown and brook, but you have your hackles raised for native-yet-invasive cutts in nearly vacant niche like the Upper Ram...
And I know of Cow lake's potential. Another example; Crawling Valley was predicted to have the next rainbow trout record; but according to Kyle McNeilly it was always intended to be a transitional fishery before pike-walleye-perch-whitefish took hold. Yes, I know it was a different intent than Cow, I am simply pointing out that I am well aware of the fertility levels and potential of many of our pothole fisheries. It is sad indeed.
Wasn't it Mr. McNeilly also promoting the stabilization of lake levels of Upper and Lower Kananaskis lakes as well? That those 2 lakes have / had the potential to grow huge trout if TransAlta could just stop messing with the littoral zone? Again, correct me if I am wrong on that account. But that was told to me as well from Jim Stelfox.
Lots of pothole fisheries going to waste. And, to completely circle back to the original point, zero retention on perch ain't solving nothing until someone cites me some studies or evidence of this much ballyhooed "deterrent effect" improving the quality of our stocked fisheries. Otherwise it's just game of regulatory one-upmanship of "oh yeah, you did that, so we'll do this to show you!" My take anyways...
I'll say no more on this dead horse; topic officially beaten to death!

P.S. Anyone know what happened to Kyle McNeilly? After he stopped writing for the AFG, he kinda fell off the face of the earth...
P.P.S. No brainer that trophy stillwater trout fisheries attract alot of attention. 20 boats on Muir mid-week by my count last spring...too bad the province isn't quite dialed into this yet in an "all-in" basis...
