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...
