Notropis cf. volucellus, Mobile mimic shiner
Mobile mimic shiners were collected while CFI was targeting Cahaba shiners for broodstock in the Cahaba River south of Birmingham, Alabama (where the two species are sympatric). Schools of mimic shiners are most frequently encountered around concentrations of river weed over sand or sand and gravel substrates in large rivers and streams. The spawning season extends from May to August throughout Alabama, and females running with eggs occur from late April to July in the Cahaba River. CFI propagated these fish simultaneously with the Cahaba shiners to compare life histories of the two species. Unlike Cahaba shiners, which cluster relatively large eggs in masses in submerged vegetation, the Mobile mimic shiners scattered tiny eggs over gravel and their early larvae were far more developed and pigmented at hatch.
