The length–weight relationships (LWRs) were estimated of seven fish species from 22 localities in the Pantanal wetland between Mach 2006 and April 2011. Fish were sampled using seven gill nets (20 × 1.5 m; mesh size: 12, 15, 18, 20, 25, 30 and 50 mm between opposing knots) and throw traps (made of 1 m3 metal cubes, covered by a 1.5 mm nylon mesh). Standard length and weight were measured and used to calculate the LWR parameters. Values for parameter b varied from 2.87 (Apistogramma borellii) to 3.29 (Hoplerythrinus unitaeniatus) and, such values are within the expected range.

来自巴西潘塔纳尔湿地的临时栖息地的七种鱼类的长度-重量关系

在2006年马赫至2011年4月之间,估计了潘塔纳尔湿地22个地区的7种鱼类的长度-重量关系(LWR)。使用7个刺网(20×1.5 m;网眼大小:12、15、18,相对结之间的距离为20、25、30和50毫米)和投掷陷阱(由1 m 3金属立方体制成,并用1.5 mm尼龙网覆盖)。测量标准长度和重量,并用于计算LWR参数。参数b的值从2.87(Apisogramma tubellii)到3.29(Hoplerythrinus unitaeniatus)不等,并且这些值在预期范围内。
