You could still be ok. The good news is your desired fish got well established before trash fish. If the trash fish get a head start on the good fish that is when there are real problems. My old pond did that.

You may have to go LMB heavy to control the trash fish. Could still have your trophy CNBG pond. Maybe just not as many trophy because of biomass of other fish.

Not an expert. Use that info at own risk.
