This study was carried out to investigate the growth and reproductive characteristics of bluefish Pomatomus saltatrix (Linnaeus, 1766) in Marmara Sea. A total 1023 samples, collected monthly from commercial fishermen between January and December 2014, was investigated. Total length distribution of the samples varied between 12,3-47,3 cm. The length-weight relation of all sample individuals is calculated as W = 0,0107L2,9574.
It was determined that the growth pattern was isometric (b=3,
P˃0,05) by the constructed t-test. Using the age-length values, the growth equation of von Bertalanffy was calculated as Lt=48,7[1-e-0,247(t+1,677)].
Growth performance index (ɸ´) was computed as 2,757 for all specimens. The monthly values of gonad somatic index (GSI) of females indicated that spawning occurred mainly between May and August with a peak in July.
