This is also particularly weird since mainland Norwegians do eat a lot of fish. Jared Diamond's Collapse goes into more detail about the Norse social hierarchy: apparently the upper classes ate a lot of beef, and seal etc was for the common man. Incidentally, similar themes repeat elsewhere: the First Fleet that founded Sydney had no fishermen at all on board, and for a long time respectable people aspired to eat beef imported from England while lobster and other seafood was only for convicts.
