Just wondering if this concept would work and what the pros and cons would be to doing this?

Also would it be too late now to add some and how big would they get if we could get them in there within the next few weeks?

The reason I ask is my father has a pond that he thinks is at most 5 foot deep and no fish are in it. He had hopes of fixing it but at this time the cost does not justify to do so.

So I am trying to figure out a way to use the BOW for either a forage pond or to grow out Tilapia.

Since Tilapia with die off in the winter, I was wondering what all the dead fish or at least the ones we could not catch would do to the water quality?

Other options would be welcomed as well.

thanks
