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 ( <i>N. caspius </i>) and 3.45 ( <i>N. pallasi </i>) with r2 ranging 0.831 to 0.988. LWR and K parameters are reported first time for <i>N. pallasi </i> from the Caspian Sea basin. The condition factor estimated was calculated from 0.94 ( <i>N. pallasi </i>) to 0.98 ( <i>N. caspius </i>) and 1.00 ( <i>P. bathybius </i>). The basic biological information on the LWRs of these three gobies will be useful as baseline information for further biological research in the region. </div> <hr /> <div style="text-align:justify;"> <br /> </div>}, number={4}, publisher={Ege University}, organization={University of Tehran}
