Possible corrective action for the overpopulation of LMB?????
Would it be at all feasible to target spawning LMB on the nest? I'm thinking diligently search for nests, remove all bass that you could catch from the nests so the eggs or fry would be vulnerable to predation (BG), seine or otherwise capture every black ball of bass fry you could? All the while stocking more large BG. As Bill has indicated above 3 to 10 bass could be all or more than you need right now. However, short of nuking or draining your pond, you'd be moving in the direction you desire.
IMO it would be a fun time on the water, harassing those LMB. Every minute I spend at pond's edge allows me to get to know the BOW better; sure beats going to work.
I've been guiding my small pond for 4 years now with ideas from this forum. I'm fascinated by the project and enjoy the results.
Please keep us in the loop.
