Arripis trutta
species of fish
Arripis trutta, known as the Australian salmon in Australia and as kahawai in New Zealand, is a South Pacific marine fish and one of the four extant species within the genus Arripis, native to the cooler waters around the southeastern Australian coasts and the New Zealand coastline. Other common names for this species include Eastern Australian salmon, Eastern Australian mackerel, bay trout, blackback salmon (or just "black back"), buck salmon (or "buck"), cocky salmon, colonial salmon, woolley Judith, newfish and salmon trout.
Although it is referred to as "salmon" in Australian English and its species epithet trutta is Latin for trout, it is not related to true salmons or trouts, which belong to the family Salmonidae of the order Salmoniformes. All Arripis species belong to the family Arripidae of the order Scombriformes.
Taxonomy
Arripis trutta was first formally described in 1801 as Sciaena trutta by Marcus Elieser Bloch and Johann Gottlob Theaenus Schneider with the type locality given as Cook Strait.
Description
Arripis trutta is a streamlined fish with a long and slender body. There is a bony ridge edge of bone beneath and in front of each eye which has obvious serrations in smaller individuals. In larger fish the scales feel smooth. The lobes of the caudal fin are equivalent in length to the head.
These fish are dark bluish-green dorsally and silvery white ventrally.
Begin with the source’s own compact description: “Arripis trutta” is species of fish. The dossier treats that line as a proposition to test through Arripis, trutta and species, 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q14245820. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1801.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
