I'm having trouble with my crayfish growing at home. A ferocious American crayfish that comes to my property without my permission from the irrigation canal connected to the rice field. It has a tremendous life force and is breeding all over Japan. Is it impossible to drive away? ?
It doesn't make much sense to call it a conditionally specified alien species.
Crawfish will multiply infinitely no matter what you do. It's more than a mint bomb.
