Dan :

I agree you should start taking out LMB and add adult BG. We have had good success with this approach under similar circumstances. I have used this approach with 2 added elements. We split the adult BG to be added into 2 seperate stockings. One in early fall (sept.) in hopes of getting a late spawn . The second stocking in late Feb. (1 mth. before expected spring 1st BG spawn) to insure that some BG remained to spawn. The other element we used on a different occasion was using a blocking net to block off a small cove in which to put both adult BG and 2-3in. ones to grow out and release in summer. They were fed pellets behind the net spawned twice and then the net was removed. Netted area was about 2000 sq ft.. Drove the bass out and let down the net 2 weeks before BG arrived. This method worked well as most BG stayed in net area grew and spawned. Some did escape I think under the net my guess 10-20 %. We did this also in another pond on a smaller scale where the net area was 800 sq. ft. ewest
