Summary Length‐weight relationships (LWRs) were estimated for seven small indigenous cyprinid fish species including Securicula gora , Osteobrama cotio , Esomus lineatus , Pethia gelius , Megarasbora elonga , Gonialosa manmina and Glossogobius aureus occurring in the Kaptai Lake, Bangladesh. Fish were collected monthly basis between March and October, 2018 from fishermen catches landed in the fish landing center, Rangamati. Fishermen operated lift net (mesh size < 0.5 cm), punti net (mesh size < 0.5 cm) and cast net (mesh size < 0.5 cm) for capturing these species. The value of exponent b ranged between 2.769 and 3.212 and regression parameter r 2 was between 0.926 and 0.992. New maximum total lengths were recorded for E. lineatus and G. manmina in this study.
