I have a SMB/YP pond and added papershell crayfish because they do better in ponds than river-adapted species. They need cover like riprap to do best. The SMB need specific spawning structures constructed of rocks as described elsewhere on this forum, and these have worked to allow spawning for me. Perhaps start another thread on SMB to get others to chime in. Adding fathead minnows up front is always good to help the initial stockers to chow down when they are added. Fun combination!
