Our 15 acre lake (30 years old) was out of balance. At our biologist recommendation we have been taking fish out at this rate for about 6 years. Fishing is much better.
It is alot of work fishing that much (and consuming the requiset amount of beer that goes along with it) but someone has to do it.
This year biologist said he would probably cut us back to 15 pounds per acre this year.
