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 …
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 …

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, …
