Catch composition, catch per unit effort (CPUE) and species selectivity of fishing gears on multi-species Kaptai Lake in Bangladesh.

Kaptai Lake, the largest artificial reservoir in Southeast Asia, is home to a diverse fish fauna that supports thousands of livelihoods and is distinguished by multi-species and multi-gear fisheries. In Kaptai Lake, the gear-based catch composition, catch rate and distribution pattern are little known. From August 2020 to April 2021, a nine-month study was conducted in five using direct catch assessment surveys and fishing effort surveys from four fishing gears, namely seine nets, gill nets, lift nets, and push nets.

The first report on a new species, Arunkumar & Basudha 2003, from Bangladesh using DNA barcoding technique.

Mahseer are large-scale fish of the Cyprinidae family that inhabit South and Southeast Asian mountainous streams, rivers, and reservoirs. and , two species of the genus, were reportedly found in Bangladesh. This study aimed to confirm the species level of specimens collected from the Sangu River.
