Masterbasser, so far I have not seen a difference. I introduced "wild" shiners into my pond at the same time as regular golden shiners. The wild ones have a black dot on their tail and are easy to see. I believe the GS revert back to their natural wild behavior in a very short time...i.e. a couple of weeks.
Sunil, you are doing things right. It only takes a 3.5 LMB to take out a 9 inch shiner...it's unusual in the South to worry about too much forage. Keep forage heavy with a close eye, it's a lot easier to ruin a forage base than it is to create one.
