In 1522 the Navy said that the sailors should have one fish between 4 men on the three fish days in a week

These fish were big salted cod, which would have been cut up and boiled to make a sort of fish stew.

Divers found a lot of cod bones on the Mary Rose, you can see some of them in the picture.

The fish would have been nearly 1 metre long, and their heads had been cut off.
