FBname: Stimpson's goby
Remark: Genus B. Mundy, pers. comm.
Comments: Benthic in lower and middle reaches of streams (Ref. 58302).  Adults inhabit mountainous streams.  Are well adapted to exist in swiftly-flowing basalt-bottomed stream habitat (Ref. 26461).  Presence of these species signify water of good water quality (Ref. 44091).  Adults are primarily herbivorous, scraping algae off rocks, while the larvae are omnivorous; occasionally caught with nets ('upena), usually after being stupefied with native plants (e.g. hola and ahuhu), a process requiring partial diversion of the stream to reduce water flow; particularly prized in July and August when the females are gravid (Ref. 44091).
