Dispersal and Dam Passage of Sonic-tagged Juvenile Lake Sturgeon in the Upper Tennessee River

More than 90,000 state-endangered lake sturgeon (Acipenser fulvescens) have been stocked into the French Broad River, Holston River, and Fort Loudoun Lake in the upper Tennessee River system. Although incidental reports of anglers catching these fish have increased, little is known about their fate after stocking. Therefore, this study was conducted to evaluate lake sturgeon dispersal throughout the system. Seven submersible ultrasonic receivers were deployed in the upper Tennessee River system and 37 juvenile fish (mean fork length = 660 mm) were surgically implanted with ultrasonic...
