Abstract
We developed standard-weight (Ws) equations for kokanee (lacustrine Oncorhynchus nerka), golden trout (O. aguabonita), and bull trout (Salvelinus confluentus) using the regression-line-percentile technique. The Ws equation for kokanee of 120–550 mm TL is log10 Ws = −5.062 + 3.033 log10 TL, when Ws is in grams and TL is total length in millimeters; the English-unit equivalent is log10 Ws = −3.458 + 3.033 log10 TL, when Ws is in pounds and TL is total length in inches. The Ws equation for golden trout of 120–530 mm TL is log10 Ws = −5.088 + 3.041 log10TL, with the English-unit equivalent being log10Ws = −3.473 + 3.041 log10TL. The Ws equation 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.
