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, we targeted ...


Aspects Of The Reproductive Biology And Growth Of The Mississippi Silvery Minnow, Hybognathus Nuchalis (Agassiz, 1855) (Teleostei: Cyprinidae) From The Pearl River, Louisiana., Arely Ramírez-García, Kyle R. Piller Nov 2018

Aspects Of The Reproductive Biology And Growth Of The Mississippi Silvery Minnow, Hybognathus Nuchalis (Agassiz, 1855) (Teleostei: Cyprinidae) From The Pearl River, Louisiana., Arely Ramírez-García, Kyle R. Piller

Southeastern Fishes Council Proceedings

The reproductive biology and growth of the Mississippi Silvery Minnow, Hybognathus nuchalis, is described from multiple sites in the Pearl River, Louisiana. Individuals were collected from August 2011 to August 2012. Ovarian weights, expressed as a percentage of body weights, peaked in December. Size structure ranged from 29.0 to 60.0 mm SL for females and 25.0 to 56.0 mm SL for males. Mature ova were found from November to January. Females reached first maturity (L50) at 37.0 mm SL and L50 for males is at 41.0 mm SL. Sex ratio (females:males) is biased ...

Distribution records for 15 fish species of conservation interest are included for Kentucky. Notropis dorsalis, previously undocumented in Kentucky, is reported for the first time (Mayfield Creek drainage). Also reported are state rediscoveries of three species thought to be extirpated from Kentucky: Ichthyomyzon gagei (Tennessee River drainage), Hemitremia flammea (Lower Cumberland and Green river drainages), and Hybopsis amnis (upper Cumberland River drainage). Unreported drainage records comprise nine species: Ichthyomyzon castaneus (Salt River drainage and Upper Green River drainage); Ichthyomyzon unicuspis (Salt River drainage and upper Big Sandy River drainage); Campostoma pullum (Tennessee River drainage); Umbra limi (Obion Creek drainage); Lepomis ...


Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith Oct 2016

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith

Southeastern Fishes Council Proceedings

Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N ...
