Coregonus artedi
species of fish
Coregonus artedi, commonly known as the cisco, is a North American species of freshwater whitefish in the family Salmonidae. The number of species and definition of species limits in North American ciscoes is a matter of debate. Accordingly, Coregonus artedi may refer either in a narrow sense to one of the several types of cisco found e.g. in the Great Lakes, or in a broad sense to the complex of all ciscoes in continental North American lakes, Coregonus artedi sensu lato.
Coregonus artedi, narrow sense
Narrowly defined, Coregonus artedi is known variously with the common names cisco, northern cisco, lake herring, chub or tullibee and its Anishinaabe name Odoonibiins. It is a pelagic fish occurring in the midwater zone of cold water lakes in North America. In the northern and western parts of its range it is also found in large rivers.
This species occasionally grows as large as 40 cm and 2.3 kg (five pounds), but is more commonly 28 to 38 cm long and 170 to 907 grams (six ounces to two pounds) in weight. It is slender-bodied and silvery with pinkish iridescence on its sides.
Diet is predominantly zooplankton and insect larvae, although fish eggs and larvae, including those of their own species are also documented.
This brief starts where responsible research should: with the source description of “Coregonus artedi” as species of fish. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q2234656. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
How to read it
