Not sure on the carrying capacity part yet, we seined in the shallow corner of the dam, it is an area that almost always has a lot of small fish. Keep in mind that there is simply not a lot of shallow areas in my 1/4 acre puddle.

I do know that the 8"+ RES I had in my aquarium were very good at catching and eating FHM up to 2-1/4" to 2-1/2", their preference was for smaller fish though. I suspect both larger RES and GSH are hammering YOY fish of all types. I may see if I can find a dozen HSB to supplement my SMB predator base.
