I am no expert on crawfish. When trying to determine what crawfish lived on my land, I read when a new crawfish type is added to you pond, the native species might just wipe the new one out, but like most things here with ponds, "it depends" on what type of crawfish live @ or around your pond now. Red swamp crawfish, might be a local to you, if so, he may not like the one you introduce to your pond. Louisiana Red swamps live from the Gulf of Mexico all the way up in some of the Midwestern states.
