Key Characteristics

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

Updated 4/16/2014. 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


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.

Active Period

Migration from first week of April to first week of June

Spawning from fourth week of September to first week of December
