As your pond has a certain maturity to it already, culling of several species should be done each year; some years more than others per species if you see specific things going on that you want to tweak.
From the other picture of the LMB, it seems like you guys do cull. Do you cull every year?
If so, you may already be doing a lot of the right things.
