I have non reproducing predators in my pond with tilapia that over winter every year and CNBG and GSH. I am having a hard time keeping enough forage in my pond. I think I might have too many predators even though they don't reproduce. If start having an issue with you forage over populating add a few more predators.

the good thing on them not reproducing is you can control the numbers of them.
