Key Characteristics

The pugnose shiner is a small (38-56 mm) straw colored minnow with a distinctively tiny almost vertical upturned mouth. This species has a complete, slightly de-curved lateral line with 34-38 scales and a dark lateral band that extends from the caudal peduncle, through the eye and around the snout. They have 8 dorsal rays. In addition, the pugnose shiner has a black peritoneum (lining of body cavity) that can be seen through the body wall of preserved specimens.

Distribution map for Notropis anogenus

Updated 12/14/2015. 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 Pugnose shiner inhabits clear vegetated lakes and vegetated pools and runs of low gradient streams and rivers. They appear to be extremely intolerant to turbidity.

Specific Habitat Needs

Macrophytes needed in Inland Lake, Littoral, Midwater Macrophytes, quiet waters needed in Mainstem Stream (3rd-4th order), Pool, Mainstem Stream (3rd-4th order), Run

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 pugnose shiner is naturally rare throughout its range. Pugnose shiner habitats tend to be difficult to sample effectively, which may present an inadequate picture of their population status. This species is susceptible to turbidity. To manage for this species practices that remove or decrease macrophyte abundance, change sediment transport, and modify shoreline or riparian areas should be limited.

Active Period

Spawning from first week of June to fourth week of July
