with a 1/2 acre pond i think you should fish it for fun.there is not alot you can do with a pond this size.after you read some of these books you will find that most say it's hard to do anything with a pond less than 1 acre and this is still hard at this size.i would not think you could grow more than a few big fish in this pond and that would only be possible working very hard.good luck,you might read some of these books before you start throwing money at this problem.
