Abstract
Weight-length data from 50 populations of smallmouth bass Micropterus dolomieu (N = 6,731) in 19 states were used to develop a revised standard weight (WS ) equation for smallmouth bass. The regression-line–percentile (RLP) technique was used to develop the proposed 75th-percentile WS equation from length-weight regressions for individual smallmouth bass populations. The proposed Ws equation, log10 WS (weight, g) = –5.329 + 3.200 log10 L(total length, mm), is valid for fish 150 mm long and longer. The English-unit equivalent, log10 WS (lb) = –3.491 + 3.200 log10 L(total length, in), is valid for fish 6 in long and longer.Keywords
