Good ideas and info above. Think about this and then go read the article by Dave Willis in the next to last PB issue on LMB/BG ponds. As you cull more LMB in #s and pounds the BG fishery responds. Usually in a bass crowded pond there are a few very big BG and very few 3-4in. ones. As you up the LMB cull the number and type of BG dynamics changes. You see more 3-5in BG and less very large BG. You may be seeing the result of your LMB culling and moving toward a balanced LMB/BG population. Understanding the balance and dynamics of your pond is the key. What are the ages and RW of the fish ? You may be ready for a electro-shock survey and pro assessment to establish a baseline.
