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. …

Life-History Aspects Of Chrosomus Oreas (Mountain Redbelly Dace) In Catawba Creek, Virginia, Dezarai Thompson, Shelby Hargrave, Gregory Morgan, Steven L. Powers
Southeastern Fishes Council Proceedings
Life-history aspects of Chrosomus oreas, Mountain Redbelly Dace, were identified using specimens collected monthly from Catawba Creek in Roanoke County, Virginia. Chrosomus oreas were found in depths up to 63.3 cm with a modest relationship between abundance and depth. The largest specimen examined was a female 64.68 mm standard length, 4.80 g eviscerated weight, and 36 months of age. The oldest specimens examined were 37 months of age suggesting a maximum lifespan of approximately three years. Spawning appears to occur from April to early July, with a mean of 243 oocytes (SD = 178) up to 1.61 mm diameter …
