Length–weight relations for 16 freshwater fish species in the Han River, South Korea

Length–weight relations (LWRs) for 16 freshwater fish collected from June to October 2018 in the Han River, South Korea, were estimated. The following species, representing the family Cyprinidae, were studied: Abbottina rivularis (Basilewsky, 1855); Acanthorhodeus chankaensis (Dybowski, 1872); Tanakia lanceolata (Temminck et Schlegel, 1846); Acheilognathus rhombeus (Temminck et Schlegel, 1846); Acheilognathus yamatsutae Mori, 1928; Carassius auratus (Linnaeus, 1758); Chanodichthys erythropterus (Basilewsky, 1855); Gnathopogon strigatus (Regan, 1908); Hemibarbus labeo (Pallas, 1776); Pseudogobio esocinus (Temminck et Schlegel, 1846); Pseudorasbora parva (Temminck et Schlegel, 1846); Pungtungia herzi Herzenstein, 1892; Sarcocheilichthys nigripinnis (Günther, 1873); Squalidus chankaensis Dybowski, 1872; Squalidus japonicus (Sauvage, 1883); Opsariichthys uncirostris (Temminck et Schlegel, 1846). The values of parameter b for all species were within the expected 2.5–3.5 range according to Froese (2006). The LWRs data for two species in this study, Acheilognathus rhombeus and Gnathopogon strigatus, were not previously available in FishBase.
