Reproductive Characteristics Of The Stripetail Darter (Etheostoma Kennicotti) Relative To Monogenean Gill Parasite Infection In Estill Fork In North Alabama, Joy L. Garcia, Zeina Celine Sleiman, Corinne N. Preacher, Bruce Stallsmith
Reproductive Characteristics Of The Stripetail Darter (Etheostoma Kennicotti) Relative To Monogenean Gill Parasite Infection In Estill Fork In North Alabama, Joy L. Garcia, Zeina Celine Sleiman, Corinne N. Preacher, Bruce Stallsmith
Southeastern Fishes Council Proceedings
What relationship exists between Aethycteron sp. gill parasite infection and the reproductive characteristics of stripetail darters, Etheostoma kennicotti? 450 E. kennicotti were collected over 11 months from Estill Fork in Jackson County, Alabama. Gonads were removed and photographed. All oocytes were counted and then classified into one of four developmental stages based on size and appearance. Gill parasites belonging to the monogenean genus Aethycteron were excised, photographed, and counted. Sexual dimorphism in length and mass was observed in E. kennicotti. The number of males found at the 25> mm SL range far outnumbered the females while almost all …
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
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 …
A Comparison Of Seasonal Reproductive Pattern In Two Sympatric Darters Of The Simoperca Clade, Etheostoma Duryi And Etheostoma Simoterum, Tiffany Bell, Elizabeth Cantrell, Bruce Stallsmith
A Comparison Of Seasonal Reproductive Pattern In Two Sympatric Darters Of The Simoperca Clade, Etheostoma Duryi And Etheostoma Simoterum, Tiffany Bell, Elizabeth Cantrell, Bruce Stallsmith
Southeastern Fishes Council Proceedings
We present results from an examination of the seasonal reproductive patterns of two closely related sympatric darter species of the Simoperca clade, Etheostoma duryi and Etheostoma simoterum. Most members of the genus Etheostoma exhibit striking sexual dimorphism, making reproductive strategy a logical point of study. Monthly collections of specimens over a one-year period were performed at a single site on the Flint River near Huntsville, Alabama. Standard length and gross somatic mass were measured for all individuals. Sex ratio was examined for possible skew. Measures of reproductive effort were monthly means of gonadosomatic index of both sexes, total oocyte count, …
Invasion Of Two Labidesthes Species Through The Tennessee-Tombigbee Waterway In Mississippi, Benjamin H. Chaffins, Calvin R. Rezac, Robert J. Ellwanger
Invasion Of Two Labidesthes Species Through The Tennessee-Tombigbee Waterway In Mississippi, Benjamin H. Chaffins, Calvin R. Rezac, Robert J. Ellwanger
Southeastern Fishes Council Proceedings
We re-identified the collections of Labidesthes sicculus at Mississippi Museum of Natural Science after a 2015 publication by Werneke and Armbruster elevated Labidesthes vanhyningi to the full species level. Following re-examination of specimens, 64% were identified as L. vanhyningi and 36% were identified as L. sicculus. During our study, a chronological review of the distribution of both species suggested bi-directional invasion through the Tennessee-Tombigbee Waterway. Prior to the connection of the two drainages, the only Labidesthes located in the Tennessee drainage was L. sicculus, where as L. vanhyningi was allopatric within the Tombigbee drainage. However, following canal construction, we …

Status And Relative Abundance Of Alabama Shad, Alosa Alabamae, In Alabama, Steven J. Rider, Travis R. Powell, Jason E. Dattilo, Gregory T. Miles
Southeastern Fishes Council Proceedings
Alabama Shad, Alosa alabamae, an anadromous fish found historically from the Mississippi River basin eastward to the Suwanee River, has experienced population declines and even extirpation in some States. In Alabama, A. alabamae have been found in rivers of the Mobile River basin and Conecuh, Yellow, and Choctawhatchee rivers in the coastal Gulf Plain. We report on our directed and targeted efforts to assess the current status and relative abundance of A. alabamae in Alabama and compare our results to past A. alabamae surveys in Alabama. We completed 52 sampling trips and expended 129.5 hours of boat-electrofishing effort targeting …
Professor Edward Drinker Cope’S Travels Through North Carolina, August–December 1869: Insights From The Transcriptions And Annotations Of Letters To His Father And His Contributions To North Carolina Ichthyology, Bryn H. Tracy, Robert E. Jenkins
Professor Edward Drinker Cope’S Travels Through North Carolina, August–December 1869: Insights From The Transcriptions And Annotations Of Letters To His Father And His Contributions To North Carolina Ichthyology, Bryn H. Tracy, Robert E. Jenkins
Southeastern Fishes Council Proceedings
Since 1870, ichthyologists have pondered Edward Drinker Cope’s two publications: “On some Etheostomine Perch from Tennessee and North Carolina” and “A Partial Synopsis of the Fishes of the Fresh Waters of North Carolina”, along with correspondences to his father while traveling in North Carolina. We transcribed and annotated four of his letters searching for further knowledge regarding his field notebook(s) and original data (meristics, morphometrics, life coloration, etc.) from his travels across NC during Summer and Fall of 1869. However, unresolved questions remained - many related to unaccounted for periods of time. We did not achieve insights into …
Checklist Of The Inland Fishes Of Louisiana, Michael H. Doosey, Henry L. Bart Jr., Kyle R. Piller
Checklist Of The Inland Fishes Of Louisiana, Michael H. Doosey, Henry L. Bart Jr., Kyle R. Piller
Southeastern Fishes Council Proceedings
Since the publication of Freshwater Fishes of Louisiana (Douglas, 1974) and a revised checklist (Douglas and Jordan, 2002), much has changed regarding knowledge of inland fishes in the state. An updated reference on Louisiana’s inland and coastal fishes is long overdue. Inland waters of Louisiana are home to at least 224 species (165 primarily freshwater, 28 primarily marine, and 31 euryhaline or diadromous) in 45 families. This checklist is based on a compilation of fish collections records in Louisiana from 19 data providers in the Fishnet2 network (www.fishnet2.net). The checklist has grown because of descriptions of three new species, new …

Diagnosis And Distribution Of Florida Sand Darter, Ammocrypta Bifascia (Teleostei; Percidae), In The Flint River, Georgia, Camm C. Swift, Gregory R. Moyer, Christine E. Fallon, Brett Albanese
Southeastern Fishes Council Proceedings
Abstract: In 2013, we observed the presence of an undocumented Ammocrypta species in the lower Flint River, Georgia. The occurrence represents the first record of the genus in Georgia. Subsequent surveys at 24 sites, using seining or snorkeling, documented additional specimens from mainstem sites (n = 3) between Albany and Bainbridge and from Ichawaynochaway Creek (n = 5 sites), a large tributary to the Flint River. We used morphological and genetic data to identify specimens to species. Morphological examination included 23 morphometric and 8 meristic characters from fifteen specimens that were compared to specimens from Williams (1975). For genetic analyses, …

An Annotated Atlas Of The Freshwater Fishes Of North Carolina, Bryn H. Tracy, Fred C. Rohde, Gabriela M. Hogue
Southeastern Fishes Council Proceedings
North Carolina’s first state-specific checklist of freshwater fish species was published in 1709 by John Lawson. Subsequent species lists with descriptions included: Brickell (1737), Cope (1870a), Jordan (1889a), Jordan and Evermann (1896-1900), Smith (1907), Jordan et al. (1930), Fowler (1945), Louder (1962), Ratledge et al. (1966), Menhinick et al. (1974). In 1991, Menhinick published “The Freshwater Fishes of North Carolina”, which is still widely in use because a comprehensive update has not been produced since its publication. The increase in the availability of historical records in globally accessible databases and the surge of collections post-1991 …
Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell
Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell
Southeastern Fishes Council Proceedings
The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the …

Physiological Ecology Of Four Endemic Alabama Species And The Exotic Asiatic Weatherfish, Misgurnus Anguillicaudatus (Cantor, 1842), Lindsay M. White, Mark E. Meade, Benjamin A. Staton
Southeastern Fishes Council Proceedings
The occurrence of Asiatic Weatherfish, Misgurnus anguillicaudatus, in Alabama, a state known for its rich biodiversity, has generated concern among conservation managers. The current study used respirometry techniques to investigate the effects of increasing temperature on four native southeastern fishes (one cyprinid, two percids, and one elassomid) and the non-native M. anguillicaudatus. A minimum of five individuals of each species were used, and three experimental temperatures were chosen to represent spring and summer averages of northeast Alabama streams (15, 20, and 25°C). Overall, mean standard metabolic rates (SMRs) for M. anguillicaudatus were low (97.01, 127.75, and 158.50 mg …
First Report Of A Population Of Western Blacknose Dace (Rhinichthys Obtusus) In The Brushy Creek System Of The Black Warrior River Drainage, Alabama, Eric Bauer, Malorie M. Hayes
First Report Of A Population Of Western Blacknose Dace (Rhinichthys Obtusus) In The Brushy Creek System Of The Black Warrior River Drainage, Alabama, Eric Bauer, Malorie M. Hayes
Southeastern Fishes Council Proceedings
Alabama is home to the southernmost populations of Rhinichthys obtusus, the Western Blacknose Dace. Within Alabama, R. obtusus is found in the Tennessee, Coosa, and Black Warrior River basins, but its presence in the Black Warrior River drainage has been limited. Until now, R. obtusus in the Black Warrior drainage has only been reported as collections of 1 to 4 specimens at a time in the Sipsey Fork drainage. Herein, we report two novel occurrences of R. obtusus in the headwaters of the Brushy Creek system in the Black Warrior River drainage including a singleton and a large population. …
Assessment Of Genetic Diversity And Hybridization For The Endangered Conasauga Logperch (Percina Jenkinsi), Gregory R. Moyer, Anna L. George, Patrick L. Rakes, J.R. Shute, Ashantye' S. Williams
Assessment Of Genetic Diversity And Hybridization For The Endangered Conasauga Logperch (Percina Jenkinsi), Gregory R. Moyer, Anna L. George, Patrick L. Rakes, J.R. Shute, Ashantye' S. Williams
Southeastern Fishes Council Proceedings
The Conasauga logperch, Percina jenkinsi is one of the rarest darters in North America afforded protection under the Endangered Species Act. Unfortunately, little is known about potential threats to the genetic diversity of this species, a narrow endemic. Loss of genetic diversity, spawning of closely related individuals, and hybridization with closely related congeners have been known to increase the rate of extinction for threatened or endangered taxa. We evaluated these risks by estimating and comparing levels of genetic diversity between P. jenkinsi and P. kathae (a closely related, morphologically similar, and more abundant congener) using twelve microsatellite loci. Specifically, we …

Southeastern Fishes Council Proceedings
The diversity and distribution of fish species occurring in the Choctawhatchee River drainage in southeastern Alabama and northcentral Florida were surveyed to obtain historical baseline information. Three hundred seventy-four sites were evaluated for species diversity and distribution in the drainage, including compilation of unpublished records from southeastern natural history museums. The greatest diversity at any single site was 37 species. Sixty-eight sites were represented by 15 species or more, and 26 sites were represented by a single species. The most frequently encountered species includes Gambusia holbrooki, Percina nigrofasciata, Esox americanus, Notropis texanus, Lepomis macrochirus, Cyprinella n. sp. cf venusta, …
