Shortnose Cisco
Coregonus reighardi (Koelz, 1924)
Also calledKurznasen-Maräne (deu) · cisco à museau court (fra) · síh Reighardův (ces) · Коротконосая ряпушка (rus) · 短吻白鮭 (zho)
The shortnose cisco (Coregonus reighardi) is a North American freshwater whitefish in the salmon family Salmonidae. One of the members of the broader Coregonus artedi species complex of ciscoes, it is native to the Great Lakes of Canada and the United States. Its population has been declining and it has disappeared from some of its earlier haunts. The last reported population was restricted to Georgian Bay off Lake Huron in Canada. It is thought that declines in the population of this fish may be linked with the arrival of the sea lamprey (Petromyzon marinus), in the Great Lakes. The International Union for Conservation of Nature has rated the conservation status of this fish as "critically endangered", and possibly extinct.
In 2024, the United States Geological Survey announced that the species had been rediscovered in Lake Superior.

Description
Reaching a maximum recorded length of 36 cm (14 in) and a maximum recorded weight of 540 g (1 lb 3 oz), the shortnose cisco is distinguished from the other whitefishes by its thicker body (nearly circular in cross-section), short head (the source of the fish's common name), and small eye.
What it does
Like many Coregonus species, the shortnose cisco is poorly understood, and little is known about its breeding or life-cycle except that it spawns in the spring at the lake bottom; the oldest specimen collected was eight years of age. The fish feeds on crustaceans, molluscs, and zooplankton.
