—Reintroduction or rehabilitation plans for fish populations in many systems (e.g., lakes) are complicated by limited data on ecological and genetic characteristics before human disturbances occurred. While no two lakes have identical physical and biological characteristics, a growing body of empirical evidence nevertheless indicates that parallel patterns of population structuring may evolve w...

Wine-Spring Creek basin, in the mountains of North Carolina’s Nantahala National Forest, is an ecosystem management demonstration site, iu which ecological concepts for management and restoration are tested. Large woody debris (LWD) is an important link between streams and the adjacent riparian forest, but evidence for the connection between LWD and trout in southern Appalachian streams is limi...

After a complete fish kill on the 2-km-long, spring-fed headwater section of Garvin Brook, brown trout (Salmo trutta) population was studied over next 29 months to examine relative roles spawning migration adults and natural reproduction in recovery process. Spawning redd counts during two seasons post-kill, repeated surveys reference zones, were conducted assess adult total changes shifting ag...

Empirical estimates of pathogen prevalence in samples of fish may underestimate true prevalence because available detection techniques are incapable of perfect detection. Trout of several species were collected from enzootic (Myxobolus cerebralis, causative agent in whirling disease) habitats, and individual fish were examined for presence of the parasite two or six times by one of four methods...
