Abstract

• This study was conducted on the species composition and abundance of Tenualosa spp. in Nga Yoke Kaung coastal area from June 2018 to February 2019. Two species of Tenualosa, namely Tenualosa ilisha and Tenualosa toli were observed in study sites. The species composition of Tenualosa spp. and other fishes caught by drift gill net using mesh size of 2.5 – 3.5 inches are described monthly in this study. The catch composition showed that the high species composition of Tenualosa ilisha was found in Sin Ma during June to September and in Nga Yoke Kaung during June to August. In Tenualosa toli, the highest composition was found in Sin Ma in October and also in Nga Yoke Kaung in December. In order to estimate the abundance of Tenualosa spp. in study areas, catch per unit effort of each species were calculated from the catch weight (kg) during study periods. The best production of T. ilisha was June to September in both study sites and the maximum CPUE value was observed in August in Nga Yoke Kaung. T. toli was more abundant during September to February in study areas. The fishing areas and fishing gears used for Hilsa fishery were recorded in this study.
