An Evaluation of Catchable Trout Movement Using Two Marking Techniques

Two marking techniques, freeze branding and subcutaneous tags, were used to evaluate movement of catchable rainbow trout (Salmo gairdneri) stocked into Rich Creek, West Virginia. These marks proved to be a valuable tool in studies requiring both rapid recognition of marked fish and identification of individuals. In general, there was a marked movement of trout downstream from the point of release, even during periods of low water conditions. Mean distances moved in both directions were 465 meters downstream and 197 meters upstream, respectively.
