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.

巴西亚马逊马德拉河漫滩湖中发现的六种鱼类的长度与重量关系

估计了马德拉河库库宾湖上六种鱼类的长度-重量关系（LWR）。在3月至2019年11月以及2020年2月之间使用刺网（10×5 m，网眼尺寸40、60、80和100 mm）对样本进行采样，在24小时内每6小时检查一次铸网（1.25×2.7 m，筛孔尺寸40 mm）在此间隔内进行了3次。这项研究报告了四个物种的新最大长度和一个物种的新的暂定LWR。
