Ayumodoki
species of fish
The ayumodoki or kissing loach (Parabotia curtus) is a species of ray-finned fish in the family Botiidae.
It is found in lakes and streams on Honshu, the largest island in Japan. Spawning grounds for kissing loach are ditches and small reservoirs for rice cultivation of a river system located in Japan. The kissing loach migrates to flooded areas, including paddy field areas, for spawning in early summer and the spawning of this species is limited after the formation of flooded areas over terrestrial vegetation. These flooded areas are the result of water from mountain streams and irrigation ponds flooding once dry land and creating man-made wetlands. As adults, Parabotia curtus migrate from these flooded paddy fields to fast moving, muddy streams and rivers like the Yodo River.
Physical description
The kissing loach has an elongated body that is colored a deep dark brown dorsally with lighter brown vertical stripes extending down the sides. The head is compressed and is pointed in the front where six barbels are located on the underside of the head near the mouth. They have large gill openings, a moderately forked caudal fin with dark stripes, lobate pectoral fins, and a lateral line present starting close to the operculum and stretching to the base of the caudal fin.
Early development
Tsukasa Abe and Tatsuya Sakamoto conducted a study which tested the early development of the kissing loach with special reference to the hatching at the early stage, as well as the movement of the larvae toward the water's surface.
Begin with the source’s own compact description: “Ayumodoki” is species of fish. The dossier treats that line as a proposition to test through Ayumodoki, species and fish, not as a finished interpretation.
Why this record matters
The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q3272249. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
