Every effort has been made to ensure that the information in the linked notes and papers is accurate until the date of last editing. It is based upon the accumulated personal experience of applied veterinary work. However, the author cannot take responsibility for incorrect interpretation or any resulting consequences.

The diagnostic processes employed are those available to field veterinary practitioners with minimal laboratory support. For example, parasitology is based on fresh tissue observations rather than fixed and stained tissue slides.

Updates of the material are inevitable as research continues on the known pathogens, but also as new pathologies emerge affecting either the existing farmed fish species or species that are new entrants to intensive aquaculture.

The contents may be used as an educational guide and are definitely not meant to become a stand-alone diagnostic tool or a manual for disease treatment.
