Length-weight relationships (LWRs) were estimated for 16 ornamental fish species from Amanã Lake and nine tributary streams, in Central Brazilian Amazonia. Sampling was carried out bimonthly for a year (2007–2008), using two sets of four gillnets (20 m × 2 m, 2,5; 3,5; 04; 4,5 cm stretch mesh size); trawls were performed with seine nets (35 m × 6 m, 3 mm stretch mesh size); native fish-traps (fyke-net like fish-traps woven from local lianas), and dip nets (0.5 m × 0.5 m stretch mesh size). Measurements were done for standard length (SL – 0.1 cm precision) and total weight (Wt – 0.01 g precision). This study provides information on the length–weight relationships for all sampled species and, in addition, provides new maximum standard lengths for six species.

巴西亚马孙 Amanã 保护区 Amanã 湖观赏鱼种的长度-体重关系

对来自巴西中部亚马逊河流域的 Amanã 湖和 9 条支流的 16 种观赏鱼物种的长度-重量关系 (LWR) 进行了估计。每两个月进行一次采样(2007-2008 年),使用两组四根刺网(20 m × 2 m,2,5;3,5;04;4,5 cm 拉伸网孔尺寸);使用围网(35 m × 6 m,3 mm 拉伸网眼)进行拖网;本地渔网(fyke-net,如由当地藤本植物编织而成的渔网)和浸网(0.5 m × 0.5 m 拉伸网眼尺寸)。测量标准长度(SL – 0.1 cm 精度)和总重量(Wt – 0.01 g 精度)。该研究提供了有关所有采样物种的长度-体重关系的信息,此外,还为六个物种提供了新的最大标准长度。
