Data on length and weight of Aegean chub Squalius fellowesii, an endemic species distributed in the Aegean drainages of Anatolia, Turkey, were used to calculate a standard weight (Ws) equation by means of the empirical percentile (EmP) method. The resulting Ws equation was log10Ws = −3.801 + 1.783·log10TL + 0.329·(log10TL)2. Over the range of application (70–220 mm TL), the EmP Ws equation was not biased by length, and the use of this equation is suggested as a way to calculate the relative weight (Wr) of Aegean chub throughout the species’ distribution area.

Abstract
Data on length and weight of Aegean chub Squalius fellowesii, an endemic species distributed in the Aegean drainages of Anatolia, Turkey, were used to calculate a standard weight (Ws) equation by means of the empirical percentile (EmP) method. The resulting Ws equation was log10Ws = −3.801 + 1.783·log10TL + 0.329·(log10TL)2. Over the range of application (70–220 mm TL), the EmP Ws equation was not biased by length, and the use of this equation is suggested as a way to calculate the relative weight (Wr) of Aegean chub throughout the species’ distribution area.File in questo prodotto:
