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

Silver chubs are typically found in deep waters of low-gradient streams and rivers as well as in lakes. This species prefers pools with clean sand and fine gravel substrates but will move into riffles to avoid silt. However, they have been found in silty areas but it is unknown if they will survive for long periods in silt (Smith 1979, Scott and Crossman 1973). In lakes, they are found at depths less than 10 m.

Specific Habitat Needs

Often deeper habitats, 9-12 m needed in River (5th-6th order), Pool, River (5th-6th order), Run

Natural Community Types

Management

To effectively manage for preferred habitats of the silver chub a watershed approach to minimize sediments and nutrient inputs is needed. Threats to this species need to be resolved.

Active Period

Spawning from first week of May to fourth week of June
