My brother and I randomly found Aurora trout in a brook trout lake last fall, and confirmed with the MNR that they were stocked accidentally, and are to be treated like a regular brook trout for this lake, meaning a limit and season were not restricted like one of the 3-year rotational lakes. We had good luck in the fall, although the ones we caught were small, and far outnumbered the brookies.
In any case, we decided to try through the ice. If we got an Aurora, great. If we got a nice brookie, excellent. If we got skunked, well, at least we tried.
After a short trail-blaze into the lake through waist-deep snow, we found ourselves on a pristine lake with only a couple inches of powder on top, and no signs of any recent access from other fisherpeople.
We pulled out 12 (and a half) Auroras in about 4 hours, and surprisingly, no brookies this time. I lost a really small one at the hole, and we released a couple of the little ones and took home our limit each. I cooked one up as soon as I got home, and it was delicious (although the seasoning I used wasn't that great).
Here's a little video I cut together. It's nothing fancy - it is very, very hard to film without any proper mount, and each of us manning two lines, and one camera... But still, I think you can see we had a good time, despite the fact that we caught no monsters, just a bunch that fit nicely in the frying pan.
