I'd be worried about the gobies before over fishing... can't put a bait on bottom without catching them. Some are the size of perch or bigger. I imagine they eat eggs out of the nest, perch eggs, trout eggs... yep caught gobies in the mouth of finger lakes tribs. I pretty much only fish one lake so I don't get to see how other lakes compare... Cayuga seems to be doing well... Better then I remember except the small mouths... they seem to be completely gone...
