Emerald shiners are not pond raised species and will not bring off a successful new batch of shiners but they will provide forage. FH may be available latter in fall. Double check with suppliers about this. Ask about source of emerald shiners if directly from lakes Erie or Ontario. Ask supplier about possibility of exotic species introduction from Great Lakes which is a very distinct possibility when the hauling water is dumped into your pond.
