Effect of Spring Discharge and Adult Abundance on Population Abundance of Two Southern Appalachian Rainbow Trout Populations

SEAFWA Journal Volume 6, March 2019

Stream-dwelling salmonid populations may be affected by both density-dependent and density-independent processes, but the relative im- portance of each may vary both spatially and temporally. We quantified population fluctuations of two unexploited rainbow trout (Oncorhynchus my- kiss) populations in western North Carolina over a 10-year period and examined the effects of spring discharge and adult abundance on recruitment. Both rainbow trout populations exhibited high degrees of temporal variability in density during the study. High spring flows that occurred during the incubation and...

Trout Population and Temperature Monitoring within Nantahala River Bypass Reach, North Carolina, in Response to Recreational Flow Releases

SEAFWA Journal Volume 3, March 2016

Recreational flow releases were established within the Nantahala Bypass Reach through the Federal Energy Regulatory Commission relicensing of Duke Energyâ??s Nantahala Project. In 2012-2013, the North Carolina Wildlife Resources Commission, in conjunction with other resource managers, attempted to monitor the influence of recreational flow events on wild rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) populations within Nantahala Bypass Reach and Nantahala Tailwater. Monitoring included temperature loggers and fish population sampling. Temperature effects of release...
