Grow fish in effluent, researcher urges. :
"That is the latest prospect from the University of Adelaide, which wants to find out why fish raised in livestock effluent in Asia are so healthy."
Well, apparently it works but I don't really want to know about it. Friends in NZ have a farm and when it got excessively wet the water was running down over the sheep field into their dam. The gold fish grew enormously big and healthy from the sheep poo additions to their water. I thought the water would have become polluted but there does seem to be some kind of biological connection between plants, poo and fish. May they research it long and hard but please don't tell me!
