I live about 8 minutes away from the largest freshwater body of water in Utah...the notorious Utah Lake. It is a large shallow lake home to many different species of fish. When the harbors ice up before the main lake caps, the white bass stack up in the harbors and become easy pickins for ice anglers. This year I would catch a white bass with a small jigging spoon (they love the blue fox rattle flash spoons btw) or jig and then cut up said white bass for cut bait. I would then tip my jigs or spoons with a small chunk o' white bass meat...then I proceed to catch as many as I want to clean.
Typically the white bass madness lasts for a few weeks on the lake until the main lake caps or until all the noise on top of the ice (from anglers, augers, etc.) will chase them to other spots on the lake. Once that happens, the crappie and bluegill move in. I typically don't expect to catch a gill or a crappie (much less a yellow perch) until the white bass swarm leaves. I guess I should expect to catch bluegills.
This past Friday I got a huge surprise. After about 15 white bass on my tipped RF spoon, I pulled up a nice 8 inch gill...and then another. I was using a larger (1/8 oz) spoon with a large chunk of white bass meat. Didn't think a gill would sniff twice at it but they INHALED it. I was under the impression that bluegill mainly feed on freshwater invertebrates, midges, larvae, etc. but now I'm starting to think that bluegill will feed on whatever is available. White bass are the most abundant sport fish in Utah Lake. Is it possible that the bluegill there have developed a taste for white bass flesh by feasting on the abundant white bass fry?
