This Spring I started working on an old 2/3 acre pond that has been untouched in 20+ years. The details can be found here: previous thread
The summary is that the pond was full of stunted LMB and no BG. I made the decision to get a healthier/bigger LMB population the hard way and not drain and start over. I culled about 23lbs/acre of LMB and added 150 4-5" BG in May. I know acheiving big LMB will be a challenge with a pond this size.
As the title of this thread says, the BG are loving the pond. I caught several that were 7+" and round and fat- I'm guessing 3 times bigger than stocked sized. I have BG on spawning beds everywhere around the pond. I also see plenty of BG and LMB YOY. Things are hopping. For entertainment my wife and I will buy crickets and earthworms and toss them out and LMB and BG gather for a free meal.
I'm guessing the BG are taking advantage of the empty niche in the pond. The LMB size remains unchanged. In a couple of hours fishing, I can catch 15-20 LMB. There is no statistically significant size/RW weight change from the previous sample (see previous thread above). The fish remain mostly in the 10" range and below 100% RW.
I'm thinking about repeating what I did last time and dedicate a day to fishing and placing all the LMB in a 55 gallon drum (with aerator). At the end of the day, I will measure and weigh all the fish and execute (so to speak) any culling plan.
