Welcome to PB. I believe I would first tackle what looks like a weed issue in the small pond. I would also fish them and keep records of the catch before I jumped into anything drastic.
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.
Without a sense of urgency, Nothing ever gets done.
Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
