Length–weight relationships of four fish species from the Nujiang River,China

Length–weight relationships (LWRs) were determined for four fish species (Akrokolioplax bicornis [Wu, 1977], Barbodes wynaadensis [Day, 1873], Glyptothorax cavia [Hamilton, 1822] and Placocheilus cryptonemus [Cui & Li, 1984]) from the Nujiang River, China. Samples were collected from March 2008 to August 2016 (frequency of sampling during the study period: once per year), using various fishing gears (set nets [mesh: 1.5 cm × 2.0 cm], fish cages [0.5 cm mesh], hook, drift gill nets [mesh: 1.0 cm × 2.0 cm × 3.0 cm] and electro fishing). Two new maximum SL were recorded for B. wynaadensis and P. cryptonemus.
