Sander glaucus
Blue pike

Key Characteristics

The bluepike has a grayish-blue body and silvery to milk-white belly without brassy or yellow mottling or overcast. The pelvic fins are transparent in small young but silvery-blue in larger fish. They have distinct dusky blotches on the webbing between the last three dorsal spines. The tip of the lower caudal lobe and the anterior tip of the anal fins are milk-white.

Status and Rank

  • State Status: X
  • State Rank: SX
  • Global Rank: G5TX

Occurrences

No known occurrences in Michigan

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

The bluepike once occurred in large, deep, clear open waters of rivers and lakes.

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

The bluepike is presumed extirpated in Michigan. Reasons for extirpation include: degradation of Lake Erie, exotic species, overfishing, and hybridization with subspecies.

Active Period

Spawning from first week of May to fourth week of May
