Infectious disease anaemia

The number of diseases reported in finfish and the methods used to detect the causative agents is vast (reviewed by Adams, 2009). The diseases currently listed as notifiable by the OIE include epizootic haematopoietic necrosis (EHN) epizootic ulcerative syndrome (EUS) gyrodactylosis (Gywdactylus 5fl/ ris) infectious haematopoietic necrosis (IHN) infectious salmon anaemia (ISA) koi herpesvirus disease (KHVD) red sea bream iridoviral disease (RBID) spring viraemia of carp (SVC) viral haemorrhagic septicaemia (VHS) (OIE, 2011). 

Biting flies cause about LJS SI 340 million in damage annually from blood loss, irritation and annoyance resulting in reduced weight and milk yields and such in sect-transmitting diseases as encephalitis, infectious anaemia and blue tongue.
