Sea fishing

Londoners love their fish. And according to a new study, in the early 13th Century they suddenly started [importing:supporting] it from as far away as the Arctic near Norway. The research is in the journal Antiquity. About the year 1000, sea fishing [increased:decreased] significantly in northern Europe. To see how that increase influenced urban growth, researchers looked at 95 [excavation:digging] sites in London. Which included about 3,000 bones from cod fish. Cod are decapitated before being dried for transport. So finding heads meant the fish were local. And the researchers found that as fish heads appear to [decrease:increase] in the early 1200s, fish tails [dramatically:systematically] increased-a sign of importation.
