Summary The present study provides the length–weight ( LW ) and length–length ( LL ) relationships for two goby species, Neogobius caspius and Proterorhinus nasalis, which were captured in the southern Caspian Sea. Total length ( TL ) and standard length ( SL ) were determined as well as weight. Specimens were collected monthly from September 2014 to August 2015 by beach seine (mesh size 10 mm). The LW parameter b for these species was 3.17 and 2.99, respectively, with a high coefficient of determination ( r 2 > .95). All LLR s were highly correlated ( r 2 > .97). Both species had no previous LWR and LLR estimates in FishBase.
