The Brachymystax lenok is relatively well-known to the Korean
people because it is designated as a natural monument, but not many
have actually seen it. It only lives in clear and uncontaminated water,
and feeds on the larvae of insects or young fish in deep rivers of steep
valleys. It is called Hot Eyed Fish in Korean due to its preference for
cold waters in steep mountains and deep valleys to cool the heat in
its eyes. It has brown spots scattered all over the body which turns
into a beautiful rainbow glaze shining from the fins during the egg-laying
season. It is a large fish, varying from 30 cm to 70 cm in size, and is
regarded as a valuable fish because of its flavorful taste. It is now
gradually diminishing in number due to overfishing and environmental
damage. The vicinity of Tong-myon, Cho'ngso'n-gun in Kangwon-do and
Sokp'o-myo'n, Ponghwa-gun in Kyongsangbuk-do Province are designated
as Natural Monuments No.73 and No. 74 respectively. The Brachymystax
lenok found in these national parks are also protected by the law.

열목어
현재는 강원도 일부와 북한에 산다. 몸의 폭이 좁고 길며 옆으로 납작하다.
기름지느러미가 있는 연어과 어류이다. 입은 작아서 입구석이 눈의 중앙을 넘지
못한다. 온몸에 자주 갈색의 작은 반점이 흩어져 있다.
