The only certain takeaway is that I would be working on my rainbow trout streamer pattern.
Otherwise, there are too many IF statements to provide clarity:
If a study is being done, which we know is happening generally but don't know the specifics for this stream, then there is at least one protocol and perhaps several to put them in for a certain time period and then you tally the results after surveys (angler, fingerling population and in this instance, we would hope, wild population). Remember, they are trying to figure out if they can reduce adults and replace with fingerlings as much as possible to save money AND, believe it or not, as a response to high wild trout densities on certain stocked streams since fingerlings are less of a competitor and the harvest crowd is not attracted by these dinks at stocking time.
If the fingerlings came from a hatchery (hatcheries) that are maxed out capacity, then is it a bigger expense to destroy them or dump them in Fishing creek? Probably the latter, and so in that sense, a way to save money, as unbelievable as that will be to the anti-gubment crowd.
What stream(s) should they dump them in during low, warm conditions that would be better?
How many are being stocked? This is not irrelevant though the word "stocked" is of course monolithic to the ANTI-STOCKS crowd that assumes any stocking, whether 100 or 100,000 = wild population damage despite mountains of evidence to the contrary, espeicially in wild brown trout streams and especially one of that quality. A big stream like that could absorb many fingerlings without flinching. The LJ did pretty well despite a very large influx of fingerlings and that water gets much warmer and had macro issues (which may be why the fishery did so well as the adults chomped the fingerlings).
If the fingerlings came from Tylersville, how much could that short trip have cost?
Raising to fingerlings costs 75 cents each or so. Raising to adult is about three bucks each, give or take. Even if the hatchery is not maxed out, it may be better to save money and dump the fingerling stockers now, given the very well publicized financial crisis the hatchery system is in.
