The present study reports on length‐weight relationships (LWRs) for 37 of the most abundant fish species in the Lefini River basin, one of the largest right bank tributaries of the Congo River in the Republic of the Congo. The study area comprised 12 stations along 103 km of the river. Each station was sampled during March 2007 to August 2008 following standardized methods utilizing five monofilament gill nets of 10, 12, 15, 20 and 30 mm mesh size. Sample size, lengths, weights, LWRs, 95% confidence intervals of a and b, coefficient of correlation r² and growth type are provided for each species. Values of allometric coefficient b of the LWRs (W = aSLᵇ) ranged from 2.556 for Synodontis nigriventris to 3.363 for Brycinus poptae. These results represent the first study of length‐weight relationships for fish species in a large affluent of the Congo basin as a whole.

来自刚果河流域中部（刚果共和国）莱菲尼河的 37 种淡水鱼的长度-体重关系

本研究报告了莱菲尼河流域中 37 种最丰富的鱼类的长度-体重关系 (LWR)，莱菲尼河流域是刚果共和国刚果河最大的右岸支流之一。研究区包括沿 103 公里河流的 12 个站点。每个站点在 2007 年 3 月至 2008 年 8 月期间按照标准化方法使用五个 10、12、15、20 和 30 毫米网孔的单丝刺网进行采样。为每个物种提供了样本大小、长度、重量、LWR、a 和 b 的 95% 置信区间、相关系数 r² 和生长类型。LWR 的异速生长系数 b (W = aSLᵇ) 的值范围从 Synodontis nigriventris 的 2.556 到 Brycinus poptae 的 3.363。
