Abstract
Ebonyshell Fusconaia ebena (38–75 mm long) were collected from Kentucky Lake, Tennessee, and tagged in the hinge ligament with coded wire tags. Mussels were then suspended in pocket nets in an embayment of Kentucky Lake. After 2 years, the 50 tagged individuals were retrieved. Survival and tag retention were 100%. Eleven individuals were sacrificed and their tags were retrieved by making a longitudinal cut through the hinge ligament. Because coded wire tags are not visible externally, they are especially useful for detecting illegally harvested mussels.
