Electric Blues...sounds like a B.B. King song Anyway I have dug into them a bit and feel free to correct me if I am wrong. So far all I have found on the Blue Florida Crayfish (Electric Blue), is they are apparently grown in large ponds and more for the pet trade and not for the dinner table.

In some pet stores they sell for as much as $25 each. They are very aggressive especially the males and should be kept in large containers with plenty of hiding places. They can reach lengths of up to 7 inches.

The Blue Florida Crayfish is native to North America; specifically, as its name would suggest, it is found only in Florida. In the wild, Blue Florida Crayfish are usually found in habitats that have distinct wet and dry seasons.
