  • ABSTRACT

    A single specimen (91.5 cm standard length) of the salmonid species, Oncorhynchus tshawytscha (Walbaum, 1792) was collected on April 19, 2022 in Sokcho-si, Gangwon-do, Korea. O. tshawytscha has the following morphological characteristics: base of lower jaw teeth is black, black spots are scattered on the dorsal section of body, and the edge of caudal fin is black. Although the species is morphologically similar to Oncorhynchus kisutch, O. tshawytscha differs from it in having black spots on the caudal fin. Molecular analysis results based on mitochondrial cytochrome c oxidase subunit I (COI) sequences showed that our specimen perfectly matched with the COI sequences of O. tshawytscha registered at the NCBI. Therefore, we suggest the new Korean name ?Wang-yeon-eo? for O. tshawytscha.
