摘要: Length-weight relationships (LWRs) are presented for four endemic fish species caught in the upper Yalu River during the yearly surveys (2017) by either electrofishing or fish cage net (5mm mesh size) as soon as the ice melted. The parameter b ranged between 2.244 in Gobio macrocephalus and 3.428 in Ladislavia taczanowskii. Additionally, the parameter a ranged between 0.004 in Misgurnus bipartitus and 0.059 in Gobio macrocephalus. All length-weight relationships were highly significant (r(2)0.8754) on a log scale.
