Abstract :In this study, length-weight relationship insert ignore into journalissuearticles values(LWR); and length-length relationship insert ignore into journalissuearticles values(LLR); of bluefish, Pomatomus saltatrix were determined. A total of 125 specimens were sampled from Samsun, the middle Black Sea in 2014 fishing season. Bluefish specimens were monthly collected from commercial fishing boats from October to December 2014. All captured individuals insert ignore into journalissuearticles values(N=125); were measured to the nearest 0.1 cm for total, fork and standard lengths. The weight of each fish insert ignore into journalissuearticles values(W); was recorded to the nearest 0.01 g. According to results of analyses, there were no statistically significant differences between sexes in term of length and weight insert ignore into journalissuearticles values(P˃0.05);. The minimum and maximum total, fork and standard lengths of bluefish ranged between 13.5-23.6 cm, 12.50-21.80 cm and 10.60-20.10 cm, respectively. The equation of length-weight relationship were calculated as W=0.008TL3.12 insert ignore into journalissuearticles values(r2>0.962);. Positive allometric growth was observed for bluefish insert ignore into journalissuearticles values(b>3);. Lengthlength relationship was also highly significant insert ignore into journalissuearticles values(P<0.001); with coefficient of determination insert ignore into journalissuearticles values(r2 ); ranging from 0.916 to 0.988.
