ABSTRACT Atlantic cod were caught in large numbers and shipped from fishing stations in North America to Europe and the Caribbean, and this has been frequently studied zooarchaeologically; however, the exchange of cod and other fish into interior North America has received less study. Cod, haddock, Atlantic herring, and Atlantic mackerel remains occur in small numbers in faunal assemblages from military sites in the northeastern United States and eastern Canada, revealing that these fish were traded up the St. Lawrence River. Freshwater fish remains identified on some of these sites reveal that they were caught or traded for in substantial quantities and provided an important protein source. No Atlantic cod or other marine fish were identified in assemblages upriver from the Niagara Falls, suggesting that the falls served as a natural barrier, separating two trade networks.
Welker et al. (Wed,) studied this question.
