The only information that I could find on it was that it is the lack of a gene that causes them to be blue. Some lobsters are blue because they are albinos, perhaps this is the same with crawdads. In the wild, you will sometimes find blue crayfish because of a genetic mutation. But there are also blue crayfish sold in aquarium stores that have been grown to be blue by giving them a feed that lacks red pigment.
