Below is a part of an email i recived from a fish farm this sounds like a good idea to me but then again it was a sales man that sent it to me any thoughts on if this will help?
To reduce the number of small bream/sunfish in the pond, preferably by increasing predation. Adding 1-2 pound largemouth bass will not solve the problem, again because they are typically too small to effectively prey on the dominant sunfish. I would recommend a heavy stocking of hybrid striped bass, a species that is especially voracious at preying on smaller bream/sunfish and is not constrained by reproductive energy requirements and stunting problems. As this species will not reproduce in your ponds, and have a lifespan of 5-7 years, they act as a finite population control method on those stunted bream/sunfish.
