First Record of Walton’s Mudskipper Periophthalmus waltoni Koumans 1941 from Narmada Estuarine Region of Gujarat, India

The present study confirmed the occurrences of Walton’s mudskipper Periophthalmus waltoni Koumans 1941 under the family Gobiidae as the first kind of record from the estuarine region of river Narmada of Gujarat, India. A total of 21 specimens were collected with the size ranging from 124 to 145 mm and from 10.7 to 26.2 g, respectively, from Jageshwar fishing sites during the monsoon period (July–September 2019). Walton’s mudskipper was reported to be found in countries like Iran, Iraq, Oman and Pakistan, but its availability in Indian waters is questionable. The present findings confirmed the occurrences of the species in the Narmada estuary, Gujarat, India drainage to the Arabian Sea.
