[quote Kevin_VanDam]I don't know much about biomass, but in my experience the best lakes for panfish have a good ratio of prey and predator fish in them. My comment about the catfish is just speculation so I won't know for sure until I can catch one and do a stomach analysis. I think it's good for Roberts to have some predator fish in it to bring up the average size of the perch. I'd much rather catch ten 10" perch than fifty 4" ones. Also, why would it become illegal to introduce another species into Roberts? Aren't all of the fish in there non-native?[/quote]
All the fish are nonnative but do you just keep adding more species to the area? Does that sound like practical management principles? It's not a question of legality, just a question of fisheries management for the whole area. Adding catfish to the equation generally means you risk predatory catfish in other waters in the area. Why chance it? I'd be interested in seeing them defend this position after finding Walleye in Ririe.![[Image: surprised.gif]](http://www.bigfishtackle.com/images/gforum/surprised.gif)
Unlike Mud Lake, Roberts is a small put and take and would make it easier for buckets to move these fish to places where we already have problems with nonnative fish such as the Southfork or maybe Ririe???
