Abstract :In this study, length-frequency, length-weight and length-length relationships and condition factors of Atlantic mackerel Scomber scombrus Linnaeus, 1758 were investigated. In 2016, a total of 163 individuals were examined by random sampling from commercial fishermen in the Sea of Marmara. It was determined that the total length distribution of the samples varied between 12.0-27.0 cm. The length-weight relationships were calculated as W=0.0040L3.2975 insert ignore into journalissuearticles values(r2=0.978); for females, W=0.0045L3.2537 insert ignore into journalissuearticles values(r2=0.973); for males and W=0.0042L3.2782 insert ignore into journalissuearticles values(r2=0.976); for all specimens. The t-test showed that the growth pattern was positive for all sex groups and for all samples insert ignore into journalissuearticles values(b˃3, P<0.05);. The relationship between length-length for all sex groups was also found to be quite strong insert ignore into journalissuearticles values(mean value: r2=0.94; P<0.05);. Fulton’s condition factor insert ignore into journalissuearticles values(K); was calculated as 0.938±0.11 for females, 0.909±0.10 for males and 0.947±0.09 for all samples. The sex ratio insert ignore into journalissuearticles values(F:M); of the population was found to be 1:0.94
