If you got pond full of 1-2lbs bass , kiss the chance of having a 10-12 goodbye. Cull the yearling bass regularly. We keep 10-20 twice a year spring and fall . It helps balance the weight brackets and the chance of big boy is greatly increase. A 1 acre pond will never thrive with a bunch of bass, especially if you wanna have eating size breams . A 2lb bass will eat hatched bream like Roseanne at a Golden Corral.
