This may be way out there ... but I wonder if RES might work with Sacramento Perch (SP). They are not as prolific as BG and might be controlled well enough by >8" SP to grow to harvestable sizes at 2 to 3 years of age. They would reduce the potential standing weights of SP I think but snail control would be a plus and the additional utilization of pond resources could mean a higher total standing weight of fish. The combination would probably also adversely affect SP recruitment but this may be good for growth of the SP. If SP recruitment failed, ladder stocking of SP (like folks do with HSB) may provide a way to counteract SP recruitment failure. Of course every species you might add will add additional complexity to the interactions ... the simpler you keep it ... perhaps the easier it will be manage. At this point, everything feels very experimental.
