Coregonus hubbsi
Ives lake cisco

Key Characteristics

Currently, experts disagree to whether C. hubbsi is a separate species from C. artedi – Genetic work is need.

Distribution map for Coregonus hubbsi

Updated 5/15/2018. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.


Ives lake cisco are found in similar habitats to lake herring, in deep inland lakes as well as the Great Lakes at depths ranging from 18 to 53 meters. They can be found in shallower depths (9-12 m) when spawning over rocky substrates.

Specific Habitat Needs

Deep water needed in Great Lake, Pelagic, Midwater

Natural Community Types


For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.

Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.


Exotic species, such as the alewife and sea lamprey, are major threats to lake herring. Eutrophication is the greatest threat to inland lake populations of lake herring. Local pollution also affects this species. Hence, exotic species and nutrient management are important to this species. In addition, the loss of food resources such as Diporeia, is an issue for this species.
