Be concerned? Good reason to be. I personally wouldn’t add the cats at this time. I prefer to give the minnows and sunfish a year to populate the pond. You can add the bass and cats simultaneously.

My answer re predator stocking. When a bass can go to sleep with its mouth open and wake up with a full belly, it’s time to stock. The minnows will disappear in about a year from predation. That’s ok. They are used to jump start the predators. The forage base is the bluegills and bass minnows that are spawned.

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
