Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait A good source for threadfin shad?

It has been said that gshad have an adverse affect on the growth of young bluegill because the shad consume zooplankton also. Is this true? Threadfins eat plankton also, but since they are small I guess that have less affect on the bluegill population? How much do golden shiners compete with bluegill?
