"From heads to tails" change in fish trade in 13th century London

New research by archaeologists from UCL, Cambridge and UCLan shows that there was a sudden switch in the fish trade in London from local supplies to imported during the early 13th century. The paper, Fish for the city: meta-analysis of archaeological cod remains and the growth of London's northern trade, appears in the June 2014 issue of Antiquities Journal.

"This discovery clarifies an important rapid shift in the demand for distant food resources of one of Europe's major centres. It shows us that local fishing could no longer keep up with this demand, that London's ecological footprint was increasingly extensive and that growing trade connections were making the world a smaller place in the century before the spread of the Black Death," said co-author Dr James Barrett of the University of Cambridge.
