Tha is Snipe, I appreciate the advice! I presumed the shiners were the issue but it's interesting to learn that the catfish and gill are the major issues with overall growth.

I'd guess by 'nuke', you mean chemically treating the pond to get rid of the undesirable fish? I'm not sure I could get the property owner on board with that, but I will do some research and inquire.

In the mean time I'll work on getting as many of the BH out as possible.

Thanks for the advice I will update.
