Saw that on the C.c FB page ... unusual, for sure.
Closest thing to it was a picture I saw of one from Weiss Lake .... front half of Crappie was normal coloration, back half was completely white (like the belly of your fish). Looked like it had been halfway dipped in bleach
But, hey ... who knows what the deal is ?? I mean ya got your regular White & Black Crappie coloration, Hybrid Crappie, Blacknose Black Crappie, Gold Crappie, the gold hue of Bee's Crappie from Maine, so why not a half/half cut either horizontal or vertical.
