freddie....I have stocked hybrid crappie....the only problem is....like albino catfish....it is not easy to locate a supplier.....very hit and miss...but I suppose nobody would want to stock them every year....so it seems i can locate them both every few years which works for me.
https://www.jmmaloneandson.com/hybrid-crappie.html We sell them. The biggest problem we have had this year is people wanting 100 or so fish and nothing else. Not a problem when they are close, but driving to Georgia/New York, etc. to deliver them doesn't make business sense, and when the people are told about the delivery cost per mile they freak out.
Heck, I had someone in Southern Florida want to buy basically 2 of every species that we sell, in advanced sizes, and expected free delivery. Sorry, that ain't going to happen.
