Discovery Of An Introduced Florida Flagfish (Jordanella Floridae) Population In Coastal Mississippi, Robert Ellwanger, Samuel E. Hunt, Calvin R. Rezac, Matthew D. Wagner
Southeastern Fishes Council Proceedings
The recent discovery of Jordanella floridae (Florida Flagfish) in Harrison County, Mississippi represents the first known occurrence of the species in the state. Native along the Atlantic and Gulf Coasts of Florida from Jacksonville to Tallahassee, this species has been introduced outside of its range via aquarium introductions. We hypothesize that an aquarium introduction was also the source of the newly discovered population, which has persisted at the location since 2020. Multiple collections of the species have been taken from a small waterbody which has a direct connection to the Tchoutacabouffa River (25mm-47mm TL). While it is unknown if this …

Aspects Of Distribution, Abundance, Habitat, And Life History Of The Caddo Madtom (Noturus Taylori), A Narrow Endemic Of The Ouachita Highlands, Brittany L. Mccall, Brook L. Fluker
Southeastern Fishes Council Proceedings
The Caddo Madtom, Noturus taylori, is a small catfish endemic to the Ouachita Mountain ecoregion in Arkansas, with habitat altered by land use practices and reservoir dams. We examined aspects of distribution, abundance, habitat, and life history of N. taylori during seasonal sampling from winter 2016 through fall 2017. Our sampling data were concordant with previous studies that suggested N. taylori is more widespread and has higher catch per unit effort in the Caddo River drainage when compared to the upper Ouachita River drainage. We did not detect N. taylori in the Little Missouri River drainage, where it is …
Morphological Differences Align With Habitat Partitioning Among Three Species Of Percina (Percidae: Actinopterygii) In The Roanoke River, Virginia, Michael M. Calvert, Steven L. Powers
Morphological Differences Align With Habitat Partitioning Among Three Species Of Percina (Percidae: Actinopterygii) In The Roanoke River, Virginia, Michael M. Calvert, Steven L. Powers
Southeastern Fishes Council Proceedings
The upper Roanoke River has three species of Percina (P. nevisense, Chainback Darter; P. roanoka, Roanoke Darter; and P. rex, Roanoke Logperch). Resource partitioning appears to be a key component of maintaining diverse fish assemblages with habitat and food partitioning cited as especially important in communities containing members of the same family. Some aspects of the diets of these species have been documented in the literature with only modest differences among them. Microhabitat data for adults of these species have also been published revealing differences in habitat occupied by each with P. roanoka living in the fastest, shallowest …
