I went to a fish hatchery the other day and fed the trout. They have a really good setup. They have 8 concrete runways about 4ftx150ft each with different sized fish in each one. The first runway has 1-4 inches, second 5-8 and so on. They charge 1.50 per person to get in, then 1.00 per bag for fish food. The bag holds, maybe three handfuls. Basically, you pay to feed their fish with food you just bought for them. Not a bad gig, cause then at the end of each year, they sell out to stock ponds and keep the breeders for next year. Has anyone here tried doing something like that even just for your own use? I thought of maybe getting one of those large stock tanks and putting some fingerlings in it and raising them to eating size. Any ideas?
