We developed standard-weight (Ws) equations for kokanee (lacustrineOncorhynchus nerka), golden trout (O. aguabonita), and bull trout (Salvelinus confluentus) using the regression-line-percentile technique. The Wsequation for kokanee of 120–550 mm TL is log10Ws= −5.062 + 3.033 log10TL, when Wsis in grams and TL is total length in millimeters; the English-unit equivalent is log10Ws= −3.458 + 3.033 log10TL, when Wsis in pounds and TL is total length in inches. The Wsequation for golden trout of 120–530 mm TL is log10Ws= −5.088 + 3.041 log10TL, with the English-unit equivalent being log10Ws= −3.473 + 3.041 log10TL. The Wsequation for bull trout of 120–850 mm TL is log10Ws= −5.327 + 3.115 log10TL, with the English-unit equivalent being log10Ws= −3.608 + 3.115 log10TL.
