Cole, we have a res in the SW part of KS that the bio there is experimenting with hybrid crappie. I think this is summer #6 or 7-lost track, but recruitment has been nearly non-existant in that impoundment. Don't take that to mean they don't reproduce because they can, but to what degree-we have little data.
TJ on the forum here probably knows more about hybrid crappie than the State of KS does.. maybe he'll see this and answer your question better.
I can tell you that forming a triploid requires a very small amount of eggs right after fertilization are compressed to around 3000psi to split the chromosomes into that triple XXX instead of XXY, which determines absolute sterility.
That is super labor intensive and would be extremely costly for a private sector farm to justify cost-wise.
