Length-weight relationship and condition factor of three endemic fish species, Ponticola bathybius, Neogobius caspius and Neogobius pallasi (Perciformes: Gobiidae) from the Southern Caspian Sea basin, Iran

In this study, the length-weight relationships (LWRs) and condition factors were estimated for 445 specimens belonging to three gobiid species viz. Ponticola bathybius (Kessler, 1877), Neogobius caspius (Eichwald, 1831) and Neogobius pallasi (Berg, 1916) from the Southern Caspian Sea basin. Total length and total weight of the examined specimens ranged 4.9-28.3 cm and 0.64-263.4 g, respectively. The length-weight parameter b of the studied species found between 2.47 (N. caspius) and 3.45 (N. pallasi) with r2 ranging 0.831 to 0.988. LWR and K parameters are reported first time for N. pallasi from the Caspian Sea basin. The condition factor estimated was calculated from 0.94 (N. pallasi) to 0.98 (N. caspius) and 1.00 (P. bathybius). The basic biological information on the LWRs of these three gobies will be useful as baseline information for further biological research in the region.
