Salmon and Models of Social Complexity on the Northwest Coast

HANSON, Diane K.

 

 

Traditionally, there has been a strong assumption that increased exploitation of anadromous salmon (Oncorhynchus spp.) was associated with the development of complex social organization on the Northwest Coast. Models emphasizing associations between complex social organization and subsistence changes were evaluated using faunal data from 15 archaeological sites in the southern Strait of Georgia of coastal northwestern Washington and southwestern British Columbia. Sites sampled using 6.4mm (1/4-inch) mesh screens, and had the results presented as Numbers of Identified Specimens (NISP) were used in the study to reduce variation caused by sampling methods. Common taxa discussed in the models were used in the assessment. Flatfish were compared to salmon; and true cods (Gadus macrocephalus) and Perciformes (perches [Embiotocidae], rock fish [Scorpaenidae], sablefishes [Anoplopomatidae], greenlings and lingcods [Hexagrammidae] and sculpins [Cottidae]) were compared to salmon. Perciformes are similar to the term “roundfish” used by Croes and Hackenberger (1988). Roundfish were more important in sites from the archipelago while flatfish were more common in sites near the sand and mud substrates of the Fraser River Delta, but not along the river channels. Sea mammals and artiodactyls were also compared to address those models that postulated an increase in land mammal use after salmon intensification decreased. The conclusion based on these data, is that salmon were not increasingly exploited during the Marpole phase, a period of presumed complex social organization, but during the Developed Coast Salish horizon when social organization was assumed to have become simpler. Mammal exploitation also increased during the later phase. The increasing emphasis on seals in mainland sites may be caused by expanding riverine technology to exploit other available species more efficiently rather than expanding the technology to offshore environments. The data best supported models that described more complex adaptations to regionally accessible resources and those that described an increasingly terrestrial focus to increase productivity.
