Total length (LT) and mass measurements of 28 596 specimens of European chub Leuciscus cephalus, collected from a variety of waterways across Italy, were used to compute standard mass (Ws) equations by both empirical percentile (EmP) and regression line percentile (RLP) methods. The use of the EmP Ws equation [log10 Ws = −4·79 + 2·68 log10 LT + 0·10(log10 LT)2] to compute relative mass (Wr) of L. cephalus in Italy is suggested, as it was not influenced by length-related bias (LT range of application = 70–470 mm).

Abstract

Total length (LT) and mass measurements of 28 596 specimens of European chub Leuciscus cephalus, collected from a variety of waterways across Italy, were used to compute standard mass (Ws) equations by both empirical percentile (EmP) and regression line percentile (RLP) methods. The use of the EmP Ws equation [log10 Ws = −4·79 + 2·68 log10 LT + 0·10(log10 LT)2] to compute relative mass (Wr) of L. cephalus in Italy is suggested, as it was not influenced by length-related bias (LT range of application = 70–470 mm).
