Abstract :Objective: The present study reports morphometric characteristics for Pagellus acarne caught by trawl from the Antalya Gulf insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Mediterranean-Turkey);. Morphometric characters were measured directly on the fish body insert ignore into journalissuearticles values(15 characteristics); and head insert ignore into journalissuearticles values(7 characteristics);. Meristic characters were counted. Length-weight relationship was calculated using the equation W = aTL b . 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 insert ignore into journalissuearticles values(for the lenght of the base of ventral fin); to 0.51 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Weight increased allometrically with length);.
