Kiyi

Key Characteristics

This salmonide has a pointed snout with a lower jaw that extends slightly beyond the upper jaw. The lower jaw and upper lip are darkly pigmented. This species has a large eye that is nearly equal to its snout length. The lateral line scales are usually 73 to 87.

Distribution map for Coregonus kiyi

Updated 1/31/2017. 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.

Habitat

This deep, cold water species is endemic to the Great Lakes (except Lake Erie).

Specific Habitat Needs

55-183 m depth water needed in Great Lake, Pelagic, Midwater

Natural Community Types

Methodology

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.

Management

Exotic species are a threat to this species. Manage introduced species to limit competition (e.g. alewife, rainbow smelt) or food web disruption (e.g. loss of Diporeia). Eutrophication may also be a limiting factor interfering with reproduction (Colby et al. 1972).

Active Period

Breeding from first week of November to fourth week of December
