Abstract

Specimens of four fish species (Garra nujiangensis Chen, Zhao & Yang, 2009, Poropuntius opisthopterus (Wu, 1977), Creteuchiloglanis macropterus (Ng, 2004), and Glyptothorax lanceatus Ng, Jiang & Chen, 2012) were caught in the Nujiang River, China. Fish were sampled between May 2017 to July 2021 in irregular intervals, using gill nets (mesh sizes 6, 10, and 16 cm) and cage nets (mesh size 1 cm). Total length (to nearest 0.1 cm, L) and total weight (to nearest 0.001 g, W) were determined. Length-weight relationships (LWRs) were estimated through the linear regression of W = aL^b. The r² values for all LWRs estimates were all above .96, indicating that no serious outlier values were included in the samples.

怒江四种本地鱼类的长重关系

四种鱼类的标本(Garra nujiangensis) Chen, Zhao &;杨，2009,opisthoterus Poropuntius (Wu, 1977)， Creteuchiloglanis macropterus (Ng, 2004)， Glyptothorax lanceatus Ng, Jiang等;Chen, 2012)在怒江被捕获。在2017年5月至2021年7月期间，采用刺网(网目尺寸为6、10和16厘米)和笼网(网目尺寸为1厘米)不定期取样。测定总长度(最接近0.1 cm, L)和总重量(最接近0.001 g, W)。通过W = aLb的线性回归估计长度-权重关系(LWRs)。所有LWRs估计值的r2值均大于0.96，表明样本中不存在严重的异常值。
