Channel catfish virus disease (CCVD) is an acute infection of cultured fry and fingerling channel catfish (Ictalurus punctatus). The disease occurs primarily during summer and, with few exceptions, in fish less than 4 months old. The causative agent, the channel catfish virus (CCV), is a member of the herpesvirus group. Since its first identification (Fijan 1968), it has been isolated from infected fish in most areas of the United States where channel catfish are cultured.
