Thoughts:
Stunted bass with ok bream fishing. It should be hard to have stunted bass with plentiful bluegills. Wrong sized prey? A bass needs prey that is 1/4 to 1/3 it’s size. And it needs a lot of them. Minnows and baby bluegills should feed larger bluegills and baby bass.

Adequate cover for young fish?

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
