Trends in Biomass and Relative Weight of Brook Trout in Response to Introduction of Non-native Brown Trout in an Appalachian Mountain Stream
SEAFWA Journal Volume 9, March 2022
Native brook trout (Salvelinus fontinalis) have been declining in many areas of their range partially because of introduction of nonnative salmonids. Brook trout biomass and relative weight in the Conway River, Virginia, were evaluated for 24 years using regression to discern trends po- tentially associated with colonization of brown trout (Salmo trutta). The Rapidan River is adjacent to the Conway River and has brook trout but not brown trout, and thus this river was sampled over similar time intervals and served as a reference stream for this case...
