Neogobius bathybious fish were caught in south-western coastal waters of the Caspian Sea, from Anzali to Zibakenar, by bottom trawl.

Four different parasites were isolated from the fish including Dichelyne minutes which with %85.56 prevalence and %65.76 intensity was the most important infecting parasite. Corynosoma strumosum showed %51.54, Anisakis sp. %12.37 and Eustrogylides excises %1.03 prevalence as the other isolated parasites in fish
