Status of the dirty darter, Etheostoma olivaceum, and bluemask darter, Etheostoma (Doration)sp. , with notes on fishes of the Caney Fork River system, Tennessee
- Univ. of Alabama, Tuscaloosa (United States)
Seventy-six localities were sampled in the Caney Fork River system and adjacent Cumberland River tributaries. Etheostoma olivaceum was found in small creeks from nine tributaries of lower Caney Fork River and three tributaries of the Cumberland River in the Nashville Basin physiographic province. The species was most abundant around slab rocks and rubble over bedrock in slow to moderate current. Etheostoma olivaceum was common throughout its small range; however, given widespread habitat degradation from agriculture, the species should retain its [open quotes]deemed in need of management[close quotes] status in Tennessee. The bluemask darter, Etheostoma (Doration) sp., was collected in slow to moderate current over sand and gravel in Collins River, Rocky River, Cane Creek, and Caney Fork River. All four populations were isolated upstream of Great Falls Reservoir in the Highland Rim physiographic province. The species was found in a 37-km reach of Collins River but was restricted to reaches of 0.2 to 4.3 km in the other three streams. Threats to the species include pesticides from plant nurseries, siltation, gravel dredging, and acid mine drainage. The authors recommend that the bluemask darter be listed as state and federally protected. Two new records were established for the rare Barrens darter, Etheostoma forbesi, in lower Collins River and Barren Fork River, and eight previously unknown records of the species were identified from older museum collections. 21 refs., 1 fig., 1 tab.
