Summary The length–weight relationships were determined for two fish species ( Callionymus curvicornis Valenciennes, 1837 and Johnius fasciatus Chu, Lo & Wu, 1963) belonging to two families. Fish samples were collected using commercial trawls (mesh sizes: 70 mm) and the frequency of use three times during each sampling period from Sanniang Bay, China. Samples were collected quarterly from October 2016 to July 2017. The allometric coefficient ( b ) of length–weight relationship varied from 2.75 for Callionymus curvicornis to 2.92 for Johnius fasciatus . Length–weight relationships for these two fish species were determined for the first time.
