Angler Opinions Regarding Catfish Management in Tennessee

Emphasis on catfish management has increased in Tennessee, and in 2003 the Tennessee Wildlife Resources Agency adopted new regulations protecting trophy-sized catfish by restricting recreational harvest of catfish >864 mm to one fish per day and eliminating all commercial harvest of catfish >864 mm. A statewide survey on licensed catfish anglers was conducted in fall 2000, 2005 and 2006 to determine if angler responses changed following implementation of these regulations. Before the regulation change, catfish anglers generally supported protecting trophy-sized catfish but angler...


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...


Weight-length Relationships and Growth Data for Blue Catfish from Four Tennessee Waterbodies

The blue catfish (Ictalurus furcatus) is an important sport and commercial species in Tennessee for which state-specific biological data are lacking. We report weight-length relationships and age and growth data for blue catfish (n = 773) collected from three exploited and one unexploited Tennessee waterbodies: Lake Barkley, Kentucky Lake, and the Mississippi River, and Fort Loudoun Reservoir. There were significant differences between blue catfish weight-length relationships between waterbodies. Catfish age ranged from age 0 to 34 and length at age estimates were significantly...
