I did something similar in my 1 acre pond. I have been battling bullheads since all of the Texas rain filled my pond up this past spring. A few months ago, I counted 5 individual balls of baby bullheads at one time in various spots around the pond. The next week I went and picked up 25 adult LMB based on a thread I posted here. I haven't seen a single bullhead swarm since!

It was a little earlier in my stocking plan then I wanted to put the LMB in, but it was that or have my pond taken over by bullheads.

Now I'm a little worried that this wild bunch is just beating my fledgling forage base to a pulp! Oh well, they're fun to catch!
