For those who smoke and dry foods - smoked fish may provide the tasty, quality protein as well.
Way in the past on a long trek ... I picked up one smoked whitefish in Blind River on the 'North Shore' of North Channel, Lake Huron, Ontario. It was wrapped in lightly waxed food wrap and then in newspaper.
I car camped North through Sault Ste. Marie into Wisconsin and from there through Minnesota, North Dakota, Montana, Idaho, through Washington to Port Angeles .. until it was all gone.
By the time supper rolled around at the end of every exhausting day and shelter was up, I was sufficiently hungry (outdoors - who knew?) that I ate happily what I prepared for my plate The smoked fish was delectable, greatly anticipated and immediate the whole trip. No refrigeration.
Maybe it's my constitution Maybe it's he smoke. My experience would encourage me to consider smoked fish as a light, un-refrigerated protein for covering the many miles next time I hike or car camp again.
