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 (W ₛ) equation by means of the empirical percentile (EmP) method. The resulting W ₛ equation was log ₁₀W ₛ = −3.801 + 1.783·log ₁₀TL + 0.329·(log ₁₀TL) ². Over the range of application (70–220 mm TL), the EmP W ₛ equation was not biased by length, and the use of this equation is suggested as a way to calculate the relative weight (W ᵣ) of Aegean chub throughout the species’ distribution area.
