Yes, the 1973 article from Organic Gardening seems to be the granddaddy to the ehow article. Since 1973, has anyone had success with this method? A while ago, I saw some postings about a guy who was dead set on barrel fish--maybe on this forum, but from a few years ago--he got everything set up and was giving week by week updates on his fish. Then--he stopped posting. No more fish updates. So it seems there is some critical point when these fish ventures fail. Maybe because of the difficulty of daily maintenance--if you have to leave for a couple of days, your fish die. Or maybe they reach a certain size and the barrel becomes too small an environment. We won't know without more research!
