Özet: Objective: The present study reports morphometric characteristics for Pagellus acarne caught by trawl from the Antalya Gulf (Mediterranean-Turkey). In addition, length-weight relationships are also estimated and compared with those estimated from other areas. Methods: Individuals of P. acarne were collected during September - December 2011 from trawl surveys conducted in the Antalya Gulf (Mediterranean-Turkey). Morphometric characters were measured directly on the fish body (15 characteristics) and head (7 characteristics). Meristic characters were counted. Length-weight relationship was calculated using the equation W = aTLb. Results: During the study period, a total of 360 specimens of P. acarne, ranging in size from 8.9 to 26.7 cm in total length and from 7.7 to 275 g in total weight, were collected. The length-weight relationship for all individuals was described by the parameters a = 0.0057 and b = 3.29. From the twenty one morphometric characters the13 were showed allometric growth according to TL while the 8 morphometric characters were showed isometric growth according to TL. The proportions of the examined morphometric characters were ranged from 0.02 (for the lenght of the base of ventral fin) to 0.51 (for the preanal distance). Conclusion: The morphometric characters were showed strong correlation with the TL. Length - weight relationship showed that the P. acarne  populations grow allometric (Weight increased allometrically with length).
