I have a 7 acre lake . I never put a bream back unless it is 12 inches or better and never take a bass out . There are 4 of us that do this . Helps the size for sure . 10-12 yrs . ago I took 2500 a year for several years . Bass are small but keep bream in check . Have caught a couple of 7 lb. bass in the last 5 years .
