Proposed standard-weight (W-s) equations for kokanee, golden trout and bull trout

We developed standard-weight (Ws) equations for kokanee (lacustrine Oncorhy nchus nerka), golden trout (O. aguabonita), and bull trout (Salvelinus conf luentus) using the regression-line-percentile technique. The W-s equation f or kokanee of 120-550 mm TL is log(10)W(s) = -5.062 + 3.033 log(10) TL, whe n W-s is in grams and TL is total length in millimeters; the English-unit e quivalent is log(10) W-s = -3.458 + 3.033 log(10) TL, when W-s is in pounds and TL is total length in inches. The W-s equation for golden trout of 120 -530 mm TL is log(10)W(s) = -5.088 + 3.041 log(10)TL, with the English-unit equivalent being log(10)W(s) = -3.473 + 3.041 log(10)TL. The W-s equation for bull trout of 120-850 mm TL is log(10)W(s) = -5.327 + 3.115 log(10)TL, with the English-unit equivalent being log(10)W(s) = -3.608 + 3.115 log(10) TL.
