The present study presents a method for predicting triggerfish body size (standard length and body mass) from bones recovered from archaeological sites. Regression equations were calculated from 42 fresh triggerfish. The following seven measurements were used as best predictors for body size based on the regression coefficients, reliability of the measurements and survivorship of the bones in archaelogical material: width of ethmoid, width of vomer, width of first dorsal spine, width of dorsal postcleithrum, width of atlas, width of sixth vertebra, and greatest height of basal pterygiophore. These equations enabled us to assess the contribution of fish to the economy and aided us in identifying various fishing methods.
