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...
