|Kanji in this term|
- One commonly encountered etymology suggests that ayu may derive from 饗 (ae, “hosting someone to a meal”), in reference to the way that this fish may be used in Shinto offerings. However, this would have been pronounced ape in ancient times, and while this ape did later become ahe, and a shift from -he to -ye did occur in many terms during the Muromachi period, the word ayu in reference to the fish appeared in the Man'yōshū dating to the late 700s at the latest, and is thus too old for this shift to have occurred.
- Another common etymology states that ayu may be from extinct Old Japanese term 落ゆ (ayu, “to fall, as nuts from a tree; to flow down, as liquid in a stream”), in reference to the way that ayu swim downstream to spawn in the autumn. Some references suggest that this is not very eventful and that this etymology is therefore unlikely. However, there are terms specific to the ayu downstream migration, such as 落鮎 (ochiayu, “ayu migrating downstream to spawn”) and 鮎落つ (ayuotsu, “ayu migrating downstream to spawn”), suggesting that this event has been culturally important enough that the 落ゆ (ayu) derivation may be plausible.
- Alternatively, this term may be borrowed from Ainu アイ (ay, “arrow”) in reference to how fast the fish moves. See also obsolete Japanese reading ai below.
The kanji spelling 鮎 in reference to sweetfish is specific to Japan, probably in reference to the way the fish (魚) stakes out its territory (占). There is another tale wherein Empress Jingū caught an ayu and thereby prophesied (also spelled 占) the outcome of a battle, but this is likely a folk etymology. In China and elsewhere, the 鮎 character refers instead to catfish.
- A sweetfish, an amphidromous fish of East Asia, the only member of its genus, Plecoglossus altivelis, prized for its sweet-tasting flesh. It is a game fish and is also subject to extensive aquaculture.
