ewest, have you yet to find any report of a hybrid crappie overpopulating a pond yet, empirical OR anecdotal? With the boom/bust spawning, I don't put anything out of the realm of possibilities, but so far, in ponds reporting, Hybrid Crappie have been unable to sustain a meaningful population in small ponds that are fished regularly.

NOTE: JM Malone and Sons is the Hybrid Crappie producer, with an excellent reputation for honesty and integrity, but absent any scientific study on the Hybrid Crappie, all their "reports" over the last 18 years or so are anecdotal.
