エノハはヤマメとよく似ている。
Landlocked masu salmon closely resembles yamame trout.
ヤマメ is a landlocked form of masu salmon as well, but typically refers to a different subspecies or regional variant with distinct markings. エノハ is a local name used in certain areas, while ヤマメ is more widely recognized.
The origin of the name エノハ is uncertain. It may be a regional term for a type of landlocked salmon, possibly derived from local dialect or older Japanese words. The kanji 榎葉 (enoki leaf) is likely ateji, chosen for its sound rather than meaning.
