The length‐weight relationship (LWRs) was estimated for eight fish species collected from oxbow lakes on the floodplain of the middle Purus River in western Brazilian Amazonia in January, May, and September 2012. The specimens were collected using 12 gillnets (80 m in length × 4 m in height, meshes of between 1.5 cm and 12.0 cm), which were set during both diurnal and nocturnal periods. The species had allometric coefficients ( b ) of between 2.92 and 3.37, and correlation coefficients ( r 2 ) ranging from 0.954 to 0.993 and we highlight that the work presents new data for literature.
