loach

loach
Loaches are often associated with being fish in rice paddies. I’ve heard that the character 酋 in the word 鰌 carries the meaning of “earthworm,” so the kanji 泥鰌 literally represents an earthworm in the mud. A loach isn’t an earthworm but a freshwater fish, yet because they look so similar, it’s easy to see why the association was made!

Suzuki
It’s a fish known as a “shusse-uo,” or a fish whose name changes as it grows. Yellowtail and mullet are other examples of shusse-uo. As for the name’s origin, there are various theories—for instance, that it became “suzuki” because of its beautifully pure whiteness, like something rinsed clean.

The mullet, also known as a “shusse-uo” (a fish that is called by different names as it grows). Incidentally, a fully mature mullet is called todo. There are various theories about the origin of its kanji, but it’s said that this character may be used because the body is dark and the fry have fat in their bellies.

Spanish mackerel
Spanish mackerel is famous as a fish that’s in season in spring. If you knew that, you might have guessed it the moment you saw these kanji. Sawara means “narrow belly.” It comes from the fish’s long, slender appearance. Female sawara are actually larger than the males.

catfish
Catfish have smooth, slippery bodies without the distinctive scales of most fish. The character 念 includes the meaning “to be sticky,” and it is said to have been used in reference to the catfish’s slick, viscous feel. In China, the character 鮎—which is read as ‘ayu’ (sweetfish) in Japanese—is used to mean ‘catfish.’
