Abstract. This paper presents the relations between total length and weight for ten demersal fishes from eastern Korean waters: Alcichthys alcicornis (Steindachner 1881); Cleisthenes pinetorum Jordan et Starks, 1904; Dasycottus setiger Bean, 1890; Gadus macrocephalus Tilesius, 1810; Glyptocephalus stelleri (Schmidt, 1904); Gymnocanthus herzensteini Jordan et Starks, 1904; Gymnocanthus intermedius (Temminck et Schlegel, 1843); Liparis punctulatus (Tanaka, 1916); Lycodes tanakae Jordan et Thompson, 1914; and Pseudopleuronectes herzensteini (Jordan et Snyder, 1901). Fish samples were collected seasonally between 2011 and 2017 using bottom gill net and trammel net. The values of exponents a and b from the weight–length relations (WLRs) were estimated. The WLRs for A. alcicornis, G. herzensteini, G. intermedius, and L. punctulatus were estimated for the first time, and new maximum lengths were recorded for G. herzensteini and L. punctulatus. All the relations between total length and weight were statistically significant (all r² > 0.937). The values of exponent b, estimated using simple linear least squares of log₁₀-transformed weight and length data, ranged from 2.899 to 3.416.
