Too many golden shiners GSH are not the only fish that can limit recruitment of desired sport fish. Too many bluegills in a pond will also prevent recruitment of the largemouth. High numbers of green sunfish will severely reduce the amount of minnow, shiner and yellow perch recruitment. Actually too many of out of balance fish species will significantly affect the number of sport fish fry that will survive. I am now thinking that this can be a pro or con based on goals for the fishery.
