Ken, I have no clue how the GSF got into the pond. Haven't had it that long. I did think about having someone apply rotenone, but think that all the GSF would create a feeding frenzy for the fish we stock and help th to grow quickly. I don't think they coils get back in as the closest water source is my other pond that has nothing in it, and it is a half mile away.
Great white, is having too many smallies ever a bad thing??? My plan is to keep the two species separate, and have one pond for bigger LMB, and the smallmouth are more of a project. I really enjoy catching SMB and would not care to take the appropriate number out to keep them in check. If I can keep forage (what should I use?) and I selectively harvest can I grow 2-3 pound SMB in a pond that size?
