Potential problems with external trailing antennae: antenna migration and ingrowth of epithelial tissue, a case study from a recaptured Chondrostoma nasus

Examination of a nase Chondrostoma nasus , that was carrying an implanted telemetry transmitter for 7 months, showed that the external trailing antenna of the transmitter had migrated c . 3 cm to the posterior edge of the incision. The absorbable sutures were still present, and there was epithelial tissue within the granulation encapsulating the transmitter. This tissue may have grown down from the surface along the antenna providing a potential entryway for pathogens.
