A Novel Application of Molecular Techniques to Pacific Archaeofish Remains *

Until recently, the identification of fish bone from Pacific archaeological sites generally relied upon morphological analysis of a relatively restricted number of skeletal elements. Limited morphological variation within fish families, amongst other things, has often restricted Pacific archaeofish determinations to the level of family or, in some cases, genus. We suggest that these relatively imprecise determinations may mask important aspects of prehistoric human fishing practices and subsistence patterns. This paper describes a molecular technique that allows for more precise taxonomic determinations, initially applied to the large and diverse family of Serranidae. The technique involves extraction, amplification, sequencing and analysis of mitochondrial DNA variation in the 16s ribosomal RNA gene. Following development of protocols and primers for modern reference materials, the technique was applied to an archaeological faunal assemblage from Aitutaki, southern Cook Islands.
