This study presents 49 length-weight relationships gathered from literature and our investigation pertaining to Gambusia affinis and G. holbrooki. The value of the slope b ranged from 2.44 for male G. holbrooki in Tajan River (Iran) to 3.81 for combined G. holbrooki in reservoirs of Segura River basin (Spain). The mean value of b was 3.11 (SD =0.30), which significantly higher than 3 (t-test, p<0.05). The median value of b was 3.15 and 50% of the b values ranged between 2.95 and 3.31.
