The length‐weight relationships (LWRs) of six Nemacheilid species (Schistura chindwinica, S. fasciata, S. khugae, S. minuta, S. reticulata and S. rubrimaculata) have been analyzed. Fish samples were collected on quarterly basis from March 2018 to February 2019. Sampling was performed using cast nets (mesh size 5–10 mm; about 50 sq m area covered each time and water depth was 4 ft approx.), and electrofishing (Ultrasonic Inverter Electro Fisher, 24 volts, 4 m) in the day time. The total length (TL) of individual fish was measured to 0.1 cm with a digital caliper and body weights (BW) were measured to 0.001 g with digital electronic balances. The parameters for the LWR equations were calculated, and the respective statistics such as the 95% confidence interval for parameters “a” and “b” are provided as well as the coefficient of correlation. For five species a new maximum total length has been documented.

印度曼尼普尔邦不同河流的6种Nemacheilid鱼类(Teleostei:Cypriniformes)的长度-重量关系

六个Nemacheilid物种(Schistura chindwinica,S。fasciata,S。khugae,S。minuta,S。reticulataS. rubrimaculata)的长度-重量关系(LWR))进行了分析。从2018年3月至2019年2月每季度收集鱼样品。使用铸网(网眼尺寸5-10 mm;每次覆盖面积约50平方米,水深约4 ft。)进行采样,并进行电捕鱼(超声波)逆变器Electro Fisher,白天24伏特(4 m)。使用数字卡尺将单个鱼的总长度(TL)测量为0.1厘米,使用数字电子天平将其体重(BW)测量为0.001克。计算了LWR方程的参数,并提供了相应的统计数据,例如参数“ a”和“ b”的95%置信区间以及相关系数。对于五个物种,已记录了新的最大总长度。
