Pallid Shiner (Hybopsis amnis)


Overview

Overview

Pallid Shiner (Notropis amnis), a fish listed as Endangered in Wisconsin, prefers the quiet to sluggish flows of large lowland rivers and their sloughs and impoundments, over substrates of sand or mud. Spawning occurs from late May through July.

State status

Status and Natural Heritage Inventory documented occurrences in Wisconsin

The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for Pallid Shiner (Hybopsis amnis). See the Working List Key for more information about abbreviations. Counties shaded blue have documented occurrences for this species in the Wisconsin Natural Heritage Inventory database. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations.

Note: Species recently added to the NHI Working List may temporarily have blank occurrence maps.

Species guidance


Note: a species guidance document is not available at this time. Information below was compiled from publication ER-091.

Identification: Body slender and fragile. Back pale olive yellow, sides silvery, belly silvery white and fins unpigmented. Adult length: 2 inches (51 mm).

Habitat: Medium to large rivers and streams, often at the end of sand and gravel bars. Primarily found over sand and mud in shallow, slow-moving, moderately clear, warm and well-oxygenated waters in impoundments with little or no current.

State Distribution: Mississippi River and the lower portions of major tributaries. A map outlining Pre-1977 and 1997 to Present Distribution is available.

Phenology: Virtually nothing is known except that they most likely spawn in March.

Management Guidelines: Access to the floodplains for spawning may be essential for the reproduction and survival of the pallid shiner. See summary fish management section.

Landscape-Community combinations of highest ecological priority*

Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.


* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.

Issues/threats and conservation actions

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
