Length–weight relationships (LWR) were estimated for six fish species from the Cujubim lake on the Madeira River. The specimens were sampled between in the months of March and November, 2019 and February, 2020 using gillnets (10 × 5 m, mesh size 40, 60, 80 and 100 mm) which were checked every 6 hr during a 24‐hr period and casting nets (1.25 × 2.7 m, mesh size 40 mm) performed three times in this interval. This study reports new maximum lengths for four species and a new tentative LWR for one species.
