Sunil,
Thank you for the response! I can definitely wait a year or more for the predator fish. My only reason to have it is to keep the young YP from stunting. I should have clarified, the 100-150lbs of fish per year would be an eventual goal and was total weight ( i would estimate 150-200 perch). If it took 3-4 years to get that, that is fine. The 100-150lbs was only based on what i have read on pond yields in other articles. Not doing any pellet feeding, i may only ever get to 50-75lbs. But one can hope!
