BC Conservation Data Centre: Conservation Status Report
Notropis atherinoides
Emerald Shiner
| Scientific Name: | Notropis atherinoides |
|---|---|
| English Name: | Emerald Shiner |
| Provincial Status Summary | |
| Status: | SU |
| Date Status Assigned: | May 10, 2010 |
| Date Last Reviewed: | May 15, 2019 |
| Reasons: | Only one specimen from one site has ever been confirmed in BC when it was collected in 1960 (McPhail 2007; McPhail, J.D, D. O'Brien and J. DeGisi. 1992). Overview of the distribution and biology of fishes in the Petitot River system, Northeastern British Columbia. Report for BC Environment, Peace Subregion). Additional collection efforts since 1960 have not found any additional individuals, so unknown if extant. |
| Range | |
| Range Extent: | A = <100 square km |
| Range Extent Comments: | Known from only one site in British Columbia: the Fort Nelson River at Old Fort Nelson. |
| Area of Occupancy (km2): | U = Unknown |
| Occurrences & Population | |
| Number of Occurrences: | ZA = 0 - 5 |
| Comments: | Known from only one site. It has not been collected since, despite several concerted efforts in the same area (Burrows pers. comm., McPhail et. al. undated (1998)). |
| Number of Occurrences with Good Viability / Ecological Integrity: | Rank Factor not assessed |
| Number of Occurrences Appropriately Protected & Managed: | A = None |
| Comments: | The only occurrence known is not protected; few (if any) appropriate, protected streams in the Fort Nelson/Liard drainage. |
| Population Size: | U = Unknown |
| Comments: | Unknown, but this species is usually abundant in other jurisdictions where found. |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | C = Medium |
| Comments: |
Parts of Liard/Fort Nelson drainage have been proposed as sites for hydroelectric development. Other possible risks include forest harvesting, exotic and other fish introductions or taxonomic difficulties (Haas 1998). There also are the inherent risks that face a single population. |
| Trend (in population, range, area occupied, and/or condition of occurrences) | |
| Short-Term Trend: | U = Unknown |
| Comments: | Unknown. |
| Long-Term Trend: | U = Unknown |
| Other Factors | |
| Intrinsic Vulnerability: | Rank Factor not assessed |
| Environmental Specificity: | Rank Factor not assessed |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | Life history and biological requirements assessed. |
| Inventory Needs: | The Fort Nelson/Liard drainage is poorly known in terms of distribution of small fish. There have been a couple of attempts at re-collecting this fish which have been unsuccessful, verification of its continued existence should be a priority. |
