My new pond is quite small (1/2 acre), so I think that I will face more of a challenge than you. I am considering crappie as food since I do not have them in either of my other two ponds. Osage may be the way to go if I take an aerated tank and travel in cool weather. Maybe make a field trip out of it with one of my young-adult kids. For now, I am hoping for more filling so I can add a pound of FHM on Nov 4 (last "fish day" close by). If I get blue-cat reproduction, my neighbor may want a couple in their 1 acre pond that has carp? A 15 acre pond must be very nice! Thank you for the information.
