| Abstract: | The length‐weight relationships were determined for three fish species Glyptothorax dorsalis Vinciguerra, 1890, Glyptothorax zanaensis Wu, He & Chu, 1981, and Percocypris tchangi (Pellegrin & Chevey, 1936)]. All fish were collected using drift gillnet (stretched mesh size: 4 cm) and castnet (mesh size: 1 cm) from Gongshan mountain, China. Samples were collected quarterly from July 2014 to August 2016. The parameter b of length‐weight relationship varied from 2.51 for Glyptothorax dorsalis to 3.30 for Percocypris tchangi. And the new standard length recorded for Glyptothorax dorsalis and Percocypris tchangi. |
