Wow, great info Bob!

I very much appreciate your reply. It's very helpful in understanding the fundamental reasons how a bluegill-crowded fishery could develop. I have very limited experience with this scenario.

The couple instances I have seen where ponds had lots and lots of skinny bluegill, there were few or no bass, and there were few if any bluegill longer than 6" (hence my confusion regarding the presence of large skinny bluegill in your description). My recommendations were to add 8" or larger bass at a rate of 50/acre and institute a feeding program. The rationale behind this was to convert the excess biomass of bluegill into desirable bass. It sounds like this approach is similar in concept to what you propose.

Thanks again.
