We estimated home ranges of three fish species inhabiting a fourth order stream in the Blue Ridge Mountains of North Carolina. Individuals were uniquely marked with a subcutaneous injection of acrylic paint. Cottus bairdi, Rhinichthys cataractae and Clinostomusfunduloides moved an average of 12.9, 13.4, and 19.3 m respectively, between captures. Mean time interval between captures was 128 d; 86% of recaptures were in the stream section of previous capture. Individuals may not have moved throughout the entire section length (mean length 10.4 m); thus, these values likely overestimate actual movements.
