Welcome to the club juhds! Balancing populations and size of LMB seems to be a common problem for pond meisters and is worthy of some research and soul searching.

Luckily your pond is bigger and you may have better success than those of us with little ponds. My research here at PB has taught me that a large population of stunted LMB is good for growing larger panfish, but if your goals are for larger LMB then it sounds like your pond is a bit backwards. Removing a lot of the LMB will give more room and food for the remaining LMB which will help their growth. This extra growth means that they will start eating larger prey, your larger bream and crappie populations may swing on you.

It's all very exciting to learn and apply these concepts, but the first thing you will need to establish is "Your Goals for the Pond". You have come to the right place and I am sure some of the more experienced members will have plenty of questions for you to help with their advice.

Fish on!,
