GS are bad for a pond (very bad) unless you have large predators that can eat fish that get over 12" long. Somebody years ago stocked some in a local public lake (probably thinking they were T shad). Now they (the gizzard shad) make up 60% of the fish biomass according to the last DNR gillnet study.
