Yesterday, I fed, and saw several more catfish of the 4-6 lb range as well as some more mature LMB in the 2-3 lb range. I haven't seen much of those LMB this year at all.
The Golden Shiner Brigade also sent out a patrol to sample the Optimal Grower and other feed.
I think it is very interesting that you are able to observe more fish AFTER the fish kill than before. (Is that correct?)
When the pond was at carrying capacity, everybody mostly had to stay within their "niche". Now with the loss of some of your larger fish, the other fish are moving around more?
