Length‐weight relationships of nine endemic fish species from the trans‐border river in the southern slope of the Himalaya, China

Abstract

Summary Length‐weight relationships (LWRs) were estimated for nine endemic fish species from six trans‐border rivers (Sutlej Tsangpo, Niang Chu, Kirong Tsangpo, Poi Chu, Phung Chu and Yadong River) in the southern slope of the Himalaya of China. All specimens were collected using drift gill nets (mesh size: 10, 30 and 50 mm; length: 25 m; depth: 1.2 m) and circle dip nets (diameter: 0.5 m; mesh size: 4 mm; length: 6.5 m) and small backpack electric fishing machines (12 V, 100 Hz) in May and June 2021. Each individual were measured with the precision of 0.1 cm for total length (TL) and 0.01 g for body weight (W). Statistical LWRs for all nine species were highly significant (p < .001), with correlation value r2 > 0.95. Five new maximum total length were recorded.
