Notropis photogenis
Silver shiner

Key Characteristics

The silver shiner is a slender but large (7-10 cm) minnow with large eyes and a silvery, blue/green iridescence and wide black lateral band. The snout is long with two black crescents between nostrils. The dorsal fin is almost directly above the pelvic fin.

Distribution map for Notropis photogenis

Updated 7/21/2017. 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 silver shiner occurs in medium to large streams with moderate to high gradients. This species usually occurs in pools or eddies with depths of ~110 cm immediately below riffles. They avoid heavily vegetated and silted areas. Spawning habitats are currently not defined.

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

Silver shiners are not widespread in Michigan and seem to be able to tolerate a limited amount of human impact including poor water quality. Specific threats are difficult to determine. But damming and channelizing rivers are likely to negatively affect this species due to their relatively restricted stream gradient preferences (McKee and Parker 1982).

Active Period

Spawning from first week of June to fourth week of June

Survey Methods

In small streams a backpack shocker is most appropriate. In larger rivers, a barge/boat shocker should be used. Seines are preferable since electrofishing may cause mortality.
