Proposed standard weight (W(s)) equations for interior cutthroat trout

January 1, 1997

We developed standard weight (W(s); length-specific standard weight for the species) equations for inland cutthroat trout Oncorhynchus clarki using the regression-line-percentile technique. Length and weight data from samples of 117 cutthroat trout populations (48 lentic and 69 lotic) over the interior range of the species were used. Separate W(s) equations were developed for lentic and lotic populations, as well as an overall equation. Relative weight (W(r); individual weight/W(s)) values did not change systematically with increasing fish length. No significant differences in mean W(r) were found among subspecies of cutthroat trout. Differences between lotic and lentic populations suggested the need for two separate equations.
