I just talked to the owner of the pond. It has been filled just one year. The incoming siphon is an 8" tube that for several months had NO SCREEN on it, so some fish may already have been siphoned into the pond. Now there is a screen on that tube. The lake above the dam has bluegills, crappies, perch, largemouth bass, pike, and bullheads.
The owner really has no goal other than to have "some fish" in the pond so that Cub Scouts, church groups, or invited friends and family will have something to catch. He has no desire to spend money on buying fish, feeding, or aeration.
From that I gather that all he wants me and my grandkids to do it catch "some fish" elsewhere and dump them into the pond.
I realize some of the problems with doing that, but I don't own the pond.
My own preference is to have perch, bluegills, and largemouth bass in the pond. Is this a working combination or should I opt for another mix? Thank you very much for helping me out.
