Generally, what species are LFS feeder crayfish?

As the title says, I'm just curious what species feeder crayfish from the LFS typically are.

I don't think the ones around here are Marbles, but, then again, I don't know much about crays.

After I posted this thread, it occurred to me that I have a picture of one of the feeders from around here:

ID?

Cool, those look like one of the 30 crayfishes I eat every time I go to boiling crabs or artist. hahaha

It really varies by region. I've personally seen several species of Procambarus and Orconectes, probably supplied from somewhere in the southeastern U.S.

That looks very different from any other cray I've ever seen. I like it.

Any other input on what species is pictured?

Very difficult to even guess type from the photo. Need to see the chelae (big claws) and top of the cephalothorax. IDing crays is notoriously difficult and can usually only be done by an expert. IDing the genus is probably as good as can be done.
