I always assumed everyone had crawfish somewhere in their lakes and streams but the last time I was in the White Mountains of AZ I discovered they were considered to an invasive species there. There were plenty of trout to munch on them, I would have thought they would have added to the feedstock for the fish. I guess someone from LA needs to send them a video on how to catch and cook them, then they might be decimated and efforts begin to save them from extinction.
