Another kind of "livestock". You can raise fish to eating size in barrels and even use these barrels with a complete aquaponic system, with vegetable gardening as well. There are many systems of doing this, from very simple to complex. Aeration is important, whatever the method.

lanahi, fascinating. I'm a little surprised no one responded or commented. Seems like there could be some real potential here under the right circumstances, particularly if TSHTF and native-caught (that means free) fish could be used.

I printed it the whole thing off and put it in my prepper file.

Thanks for the info.
