Thanks for the replies. Couple follow up questions:

1. Is it possible to over-cull the LMB?
2. All the BG I caught this year were fairly large. I assume all the small ones were eaten. Should I add more BG this year? I can easily do that.
3. I’m hesitant to feed the BG, as I’ve heard that it can exacerbate existing weed problems… which we have. Tons of rooted plants all throughout the pond that keep growing no matter what we do. The only thing that works is manual weed removal with cutters and rakes. I’d hate to make that worse by adding a bunch of feed into the mix. Is that a legitimate concern?
4. If LMB are not the ideal predator species, what would be? Any ideas on that?

Thanks!!
