Last year I got some white with black flake GYCB craws. In what conditions would you use these craws?

A full moon ....crawdads molt then not that they walk around like that but bass will still eat um if they see um

i usually use lighter colors in tinted water too, might want to try them then.

Sight fishing bedded fish.

Fall as a swimming jig trailer comes to mind? Since I have never seen a white crayfish or heard of one I would fish them like some sort of baitfish.

FYI: According to LSU AgCenter

Red Swamp Crawfish Procambarus clarkia

As adults, always have red pigment on their bodies.

White River Crawfish Procambarus zonangulus

Never has red pigment on its body - sometimes adults can look pink or purplish

I site fish with them and when the crawfish are molting.
