Dear Mat,
My colleagues and I touched on this issue as a corollary of a fish trade study in a methodological paper from 2008:
Barrett J, Johnstone C, Harland J, Van Neer W, Ervynck A, Makowiecki D, Heinrich D, Hufthammer AK, Enghoff IB, Amundsen C et al. . 2008. Detecting the medieval cod trade: A new method and first results. Journal of Archaeological Science 35(4):850-861.
Over the last two years we have been collecting data to address the question directly for the southern North Sea, but it will be at least a few months before we are ready to publish. Meanwhile the following papers may also be of interest:
Barrett JH, Orton D, Johnstone C, Harland J, Neer WV, Ervynck A, Roberts C, Locker A, Amundsen C, Enghoff IB et al. . 2011. Interpreting the expansion of sea fishing in medieval Europe using stable isotope analysis of archaeological cod bones. Journal of Archaeological Science 38:1516-1524.
Orton DC, Makowiecki D, Roo Td, Johnstone C, Harland J, Jonsson L, Heinrich D, Enghoff IB, Lougas L, Neer WV et al. . 2011. Stable isotope evidence for late medieval (14th-15th C) origins of the eastern
Baltic cod (Gadus morhua) fishery. PLoS ONE 6(11):e27568. doi:27510.21371/journal.pone.0027568.
Best wishes,
James
