Food Fish for Preppers

[NorthernRaider]

Please persevere with me on this.
Read a tatty free magazine that the wife brought home from the US this morning, wife had torn out a couple of pages she thought would interest me.
It was about TV documentary shows of the type seen on BBC2 BBC4, Ch 4, Discovery, Nat Geo and they were talking to assorted US / UK /AUSSIE film makers etc
The snippet the wife had picked up on was one of the crews had been involved with a program that I guess was either home improvement or garden landscaping ( yup boring I know but keep going)
I quote them
“ We are doing more and more pond installations for home steaders and preppers who want to grow Koi Carp both for ornamental use and as a food source”.
Something for us to revisit again? Keeping fast growing, easy to look after, cheap to feed fish as a back up food source? In the colder bits like the UK and Northern US areas Koi appear to be the default choice, in warmer climes like the southern US Tilapia appear to be suitable.
