Bill, I didn't mean to imply that wipers be used in spite of LMB. LMB would always be the primary predator. A heavy population of LMB will certainly do a better job of controlling crappie than will a mixed group of predators. However, it seems to me that a heavy population of LMB along with a small population of wipers, catfish, saugeye etc. will eat even more of the crappie. Adding lots of 8-12" LMB should hit this year's crappie reproduction really hard. As they get big enough to eat the 5" crappie, the LMB should go wild with this source of food.
