Fish for breakfast in Sweden and Fish cyphers

I was having an interesting discussion with Mark Curphey who mentioned that it was very strange that the Swedish eat fish for breakfast! I am British myself living in Sweden, and have actually become quite accustomed to seeing fish on the breakfast tables. Anyhow it got me thinking if there was any link I could find between fish, Sweden and cryptography so it was worth for some mention in my blog. And here it is "Fish cyphers". It is quite likely that Arne ate fish for breakfast too!
