Latest Information on the IHN outbreak in Quillayute hatchery populations from WDFW's Heather Bartlett. From the Sounds of it, the Snider Creek Program is also affected. Furthermore, wild fish collected by the guide association for the broodstock are infected as well, meaning they may end up being wasted. The Snider program has a host of problems associated with it, not the least of which is the fact that they are taking wild fish from the most fragile part of the run (early) to provide broodstock for a harvest fishery. Maybe this will serve as a wake up call to WDFW and the guides association that this program has long been doing more harm than good.
We have had outbreaks of IHNv on the Olympic Peninsula. When you
say another, I am uncertain what the frame of reference is, so I
will summarize what we know at this juncture.
Department fish health staff detected IHNv in Bogachiel winter
steelhead several weeks back. We increased the frequency of pulling
adults from the trap in order to minimize the shedding of the virus
into the watershed as well as protect the juveniles on station. We
further destroyed over a thousand adult steelhead and buried them on
site to ameliorate further risk to juveniles at the hatchery as well
as protect fish in the river.
At this time it appears juvenile steelhead on station at Bogachiel
are free of the virus so there is no need to quarantine them. We
are currently exploring management options with the tribal
co-managers for the eggs that were taken by the spawned adults that
came up positive. Iodophor, a standard disinfection process
generally precludes vertical transmission of the disease (parent to
progeny), but we are remaining vigilant to understand if all the
precautionary procedures were employed to ensure these eggs indeed
are clear of the virus.
Regardless, at this time, the virus is clearly in the watershed as
now the Snider Creek wild adult steelhead collected by the guide
association have also been identified as positive for IHNv. We have
yet to make a final determination on what to do with these adults
and their progeny.
meeting…what is the risk the 400K eggs pose from IHNv positive
adults and what to do about the Snider Creek wild steelhead program
for this broodyear.
We are keenly aware of the risks this disease, and in particular
this strain poses and take this very seriously. State, tribal and
stakeholder discussions will help to shape the final decision. Heather
