Abstract

This study was conducted to determine regional variation in GROWTH parameters of Caspian shad ALOSA CASPIA CASPIA in southern Caspian basin. Results showed that the largest specimens had 283mm total length and 171.85 g total weight in the southeast region, i.e. 277 mm total length and 145.70 g total weight in central area, 269 mm total length and 138.30 g total weight in the southwest region of the basin. Age of the specimens ranged from 2+ to 5+ in all sampling areas and there were significant differences between observed and back-calculated lengths at ages. There was a positive allometric GROWTH in the population from southeast area, while negative allometrice GROWTH was found in both central and southwest areas of the basin. In all areas, females has a b-value of WLR larger than that of males. Parameters of von Bertalanffy GROWTH function were different between males and females of each area and between the same sexes of different areas. The largest L¥ was found in the southeast area for males and in the central area for females. The highest K of Van Bertalanffy GROWTH equation was observedfor males and the lowest for females of the southeast area of the basin. t0 showed negative values in all areas with the lowest value of -0.531 for females in the southeast area and the highest value of ‑0.145 for males in the central area of the basin. The results showed that there are significant variations in GROWTH parameters of the species in the southern basin of CASPIAN SEA.
