If you search the archives long enough, you can probably find where I had a major infestation of BH in a 17 acre pond. I was catching them on lures and etc. Frustrated big time. Bill or someone here advised that LMB will eventually get them in check and they were right. Don't catch them often anymore and never see the swarms of small ones like used to see.
