Length-weight relationships for 17 fish species in the Luanhe River Estuary, Bohai Sea, northern China

Length-weight regressions (LWR, W = a × L b ) of 17 coastal fish species from the Luanhe River Estuary in northern China are presented in this study. A total of 7354 samples from 11 families were measured and weighed. The slope (b) values for LWR ranged from 2.572 in Acanthogobius ommaturus to 3.6581 in Engraulis japonicus . The median value was 3.114 in Platycephalus indicus , although 50% of the values ranged between 2.9451 to 3.2965 for the entire data set.
