People have been dehydrating (or drying) fish for thousands of years.
I know of one place where they fish for cod, landing it while it's still wriggling, but don't consider it fit for human consumption until it's been gutted, filletted, salted, nailed on wooden frames to dry, been stored for months on end, then boiled, mashed and reduced to a grey, salty, foul-smelling, awful-tasting sludge. In effect... as far removed from a nice piece of tasty fresh white cod as it's possible to get!
