I've been fishing Skegemog for for a few decades.
For ice fishing, Perch and Pike are the main, and almost only targets in winter.
Spear shacks dot the lake for Pike and Muskie when the season allows.
While Perch fishing, I've caught and released several nice bronze backs, some rock bass and other pan fish, but I don't target them.
I've also caught one small Walleye, a decent Brook Trout and one small Lake trout ice fishing on Skegemog.
Other than that its has been all Perch and Pike. of course almost anything could be possible with the huge river and lake systems its connected to.
Spring, Summer, and Fall holds a great Bass fishery with mostly bronze backs.
The Muskies run on the large side for those that have the skill and patience to catch them.
Good Luck all
