Author(s): Md. Ataur Rahman, Md. Nurunnabi Mondal, Md. Abdul Hannan, Kazi Ahsan Habib

Abstract: The study was conducted to investigate the present status of fish biodiversity and abundance of fish fauna of an Indo-Bangladesh common river Talma in Northern part of Bangladesh. The study was conducted from March to October, 2014. A total of 56 species of fishes have been recorded belonging to eight orders, 21 families and 37 genera. Cypriniformes was the most diversified fish group in terms of both number of species and individuals observed. Among 56 species, 32 species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, three species of Channiformes, three species of Synbranchiformes, one species of Beloniformes, one species of Clupeiformes and two species of Decapoda were found. The study revealed that 32.14% of fish species were threatened. Among the threatened species, 12.5% were vulnerable, 16.07% endangered and 3.57% were critically endangered. Overall values of diversity, richness and evenness indices were found 1.42, 6.64 and 0.86, respectively. From the investigation, it was found that the fish biodiversity of the Talma River has declined day by day due to over exploitation, natural causes (such as siltation, flooding, drought and calamities), construction of obstacle for fish migration and lack of public awareness.
