Fished off Bratenahl and White City today. Marked a lot of fish, right where perch should be but wondered why the bite was slow. Soon had Mayflies and those darn little Biting Flies hatching at the surface. That explained the slow bite and the bulging guts on most of the perch. Fish were running small with a lot of 7 to 9 inch fish. We kept 12 fish between 10 and 12 inches. Fish were biting best in 43 fow, four turns off the bottom.
