Hard to say...I've had great luck with them in my ponds but there's ample submergent vegetation. I know some forum members who had shrimp stocked apparently did NOT have them take. I don't know how well they would do being stocked in a pond full of BG - if you stocked higher qtys you'd improve your chances for sure.
