Abstract

The present study established the fish body and otolith dimension relationships of flathead sillago Sillaginopsis panijus (Hamilton, 1822), to assist the interpretation of growth. A total of 413 specimens were collected fortnightly from September 2018 to August 2019 off north-western Bay of Bengal. The samples ranged between 142–394 mm in total length and16-413.1 g in total weight. With fish growth, positive correlation was observed between the fish and otolith morphometric parameters. The highest coefficient of determination (R2) was observed between total length and otolith weight (R2=0.9198), followed by otolith weight and otolith width (R2=0.896). These results provide baseline information on the dimensional relationship between fish length and otolith size of this species in Indian waters, which will be helpful in future study on the food and feeding habits, growth and stock structure.
