| Abstract: | Length‐weight relationships (LWRs) for four species are presented, captured in the Dogxung Zangbo River, a main tributary of the Yarlung Tsangpo River, Tibet, China. Fish were captured in summer and autumn between May 2006 and September 2017 with three fyke nets from six sites.The results of LWRs for Schizothorax oconnori Lloyd, 1908, Schizopygopsis stoliczkai Steindachner, 1866, Triplophysa orientalis (Herzenstein, 1888), and Glyptosternon maculatum (Regan, 1905) provide basic data useful in fisheries science. They can assist in converting length data in to weight and biomass in cases where weight can not be taken during field studies. If regularly taken in an annual monitoring programm together with other parameters, using a standardized sampling procedure, they can also helpful in stock assessment of fish species in the Dogxung Zangbo River and the upper reaches of the Yarlung Tsangpo River basin. |
