Brown trout simply won't live there - no stream, warm and muddy water.
Zander has been introduced recently but I don't know how well was the introduction - too small fish to catch right now. I hope to catch some specimens this/next year.
OK, seems like most of you suggest not to deal with these bullheads. Thank you. I'll think about them in another pond.
EDIT: talked to my relative who basically lives near these ponds. We decided to postpone this thing till the next year or so.
