The hybrid crappie are just hybrids of white and black crappie. In the experiments I've helped out with the female parents were white crappie. The hybrid eggs can then be "cold shocked" to produce triploid hybrids which for the most part won't be fertile (usually 5% of the population remained diploid and reproductive after cold shock). I believe that any claims of these fish consistently growing to abnormal sizes are bogus. Hybrid crappie don't benefit from hybrid vigor to the degree that some other hybrids do. I wasn't part of any growth rate experiments, but from what I heard the hybrids did not grow more rapidly or to a larger size than the regular crappie used as controls (I was bummed to find this out ). In my opinion, the greatest advantage of hybrid crappie is that the triploid hybrids can be stocked, in limited numbers, in bodies of water that are too small to support a fully reproducing crappie population.Wonder what they were bred with to get the hybrid? White bass maybe? Anyone know?
