The study was conducted to determine the allometry variability of mosquitofish based on 10987 specimens collected from 11 localities in the southern Caspian Sea basin in summer 2021. The estimated b-values range from 2.414 for males from the coastal lagoon of Gorgan Bay to 3.911 for the population from the Sorkhroud River. In the basin, the overall mean of the b coefficient was 3.190±0.413. The growth patterns of most considered groups were positive allometric. The form factor a_3.0 indicated that body shapes were different between the areas.
