Abstract

Among 41 morphometric and meristic parameters of sobur studied in Bahmanshir River, the number of pre-pelvic, post-pelvic and total scutes were 30-32, 16-18 and 13-15 respectively. The coefficient rate between head length and caudal peduncle to standard length were found to be 28% and 23% respectively. The five parameters mentioned above are in agreement with Tenualosa ilisha species. According to this survey there are great differences between Bahmanshir river sobur and those have been surveyed in Bangladesh and Indian water resources based on the morphometric and meristic characteristics. We found that all the morphometric characters have high correlation with total length......
