Went for a few hours last night. Had a ton of bait at both spots we fished. But the first spot only produced perch. And the second spot was mostly perch with 5 or 6 crappie in the mix. Does fishing depth of our bait change the odds of catching perch vs crappie? We were in 30 fow both times. And the bait was on the bottom when we got there and came up off the bottom to the lights.
