Summary

Length-weight relationships (LWRs) of 14 species from 17 populations of salangids, which cover most species in the family Salangidae, were analyzed from 12 regions in China and Japan. A total of 952 specimens were used to estimate the relationship parameters. The allometric factor b values varied from 2.56 in Salanx cuvieri to 3.53 in Neosalanx oligodontis. Additionally, the condition factor a value was calculated setting b = 3 in the remaining six species. Nine maximum-size records and 17 LWRs of salangids are established for the first time, which will fill in some of the empty spaces on rare neotenic species in the Fishbase.
