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.

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.

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

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
