The shiners did well in the Boy Scout lake because of the amount of weed cover in shallow water. The weeds provide lots of refuge areas for the shiners to avoid predation. Shoreline shallow weeds and emergent weeds provide lots of spawning areas. With that combination it will not make any difference in survival if wild or farm raised shiners are present. Underwater vegetation beds are much better as refuge areas for small fish than artificial structure.
