Exuberant granulation tissue response associated with Neobenedenia sp. (Monogenea: Capsalidae) infestation in two cobia, Rachycentron canadum (Linnaeus).

Monogenean parasite infestations are common in captive marine teleosts, and are generally found on the skin and gills. This report describes an unusual pathological presentation of exuberant granulation tissue of the gills, suspected to be related to Neobenedenia infestation in two cobia housed together at a North Carolina aquarium.
