I think one use for male bass is to use them in a pond such as a perch pond where you want the predator to stay smaller and focus its eating of fish that have the smaller size ranges. The male bass would be a tool for biasing the predation toward small fish. Plus all male bass would not spawn in the pond and cause problems with too much bass predation of the preferred fish crop. Again - good management of the predator population can be a big asset for fishery management.
