Oregon Administrative Rules › Chapter 635 - DEPARTMENT OF FISH AND WILDLIFE › Division 7 - FISH MANAGEMENT AND HATCHERY OPERATION › Section 635-007-0970 - Fish Disease and Pathogen Categories

Current through Register Vol. 63, No. 7, July 1, 2024
(1) "Category I" or "Emergency" fish disease
			 agents are those for which there is no known treatment and that have not been
			 determined to occur in Oregon as of September 1, 2003. Disease agents in this
			 category are the European strain of Viral Hemorrhagic Septicemia (VHS),
			 Oncorhynchus masou virus (OMV) and Channel Catfish Virus (CCV). Disease agents
			 may be added to this category as they are identified.
(2) "Category II" or "Certifiable" disease
			 agents can be highly contagious, may cause catastrophic losses and do not have
			 a known cure. Disease agents in this category are the North American strain of
			 Viral Hemorrhagic Septicemia (VHS), Infectious Hematopoietic Necrosis Virus
			 (IHN), Infectious Pancreatic Necrosis Virus (IPN), Infectious Salmon Anemia
			 (ISA), Spring Viremia of Carp (SVC), and Piscirickettsia salmonis. Disease
			 agents may be added to this category as they are identified in state waters or
			 may be moved to a more or less strict category as disease concerns
			 change.
(3) "Category III" or
			 "Reportable" disease agents may be enzootic in populations or watersheds but
			 are not necessarily of such concern as to prevent all transfer or release of
			 fish. This category includes drug resistant strains of fish disease agents
			 otherwise falling in Category IV. Disease agents in this category are
			 Erythrocytic Inclusion Body Syndrome (EIBS virus), Viral Erythrocytic Necrosis
			 Virus (VEN), sturgeon iridovirus, Renibacterium salmoninarum (bacterial kidney
			 disease), Flavobacterium psychrophilum (cold water disease), Aeromonas
			 salmonicida (furunculosis disease), Yersinia ruckeri (enteric red mouth
			 disease), drug resistant strains of bacterial disease agents, Myxobolus
			 cerebralis (whirling disease), Tetracapsuloides bryosalmonae (Proliferative
			 Kidney Disease), Ceratomyxa shasta (ceratomyxosis), and Nucleospora salmonis.
			 Disease agents may be added to this category as they are identified in state
			 waters or may be moved to a more or less strict category as disease concerns
			 change.
(4) "Category IV" or
			 "Historical" disease agents are those associated with a particular area, water
			 body, or facility either in Oregon or in another state or country in which fish
			 are raised or where a disease agent is associated with an intermediate non-fish
			 host. This category also includes Category I through III diseases if previously
			 found at a particular facility but no longer occurring there. Disease agents in
			 this category are flatworms, round worms, tapeworms, ciliated and flagellated
			 parasites, myxosporean (other than Myxobolus cerebralis, Tetracapsuloides
			 bryosalmonae and Ceratomyxa shasta), microsporidian parasites (other than
			 Nucleospora salmonis), fungal agents, bacterial agents, transient viral agents,
			 and other classes of infectious agents not previously listed. Disease agents
			 may be added to this category as they are identified in state waters or may be
			 moved to a stricter category as disease concerns change.
