In your honest opinion and with your seemed expertise on the subject, do you actually believe that picture is real with up to 200 lice on it?
Thanks for your honest question, SF. Always appreciate the honesty.
Answering honestly - it is quite unusual - but not impossible. And I really don't think it is faked, neither.
I think it's worth some more explanation on the "
One has to look at the developmental rate of the sea lice to infer when & POSSIBLY where these lice loadings happened" remark:
If one did the DNA (Chinook have a great DNA baseline, generally - assuming it is a Chinook - and most likely a hatchery one that big) - one could infer watershed of origin within a small limit of error. And there's only so many hatcheries, as well. So this part should be easy to do.
Sea lice DNA as a contrast - has been unreliable for tracking as sea-lice are generally traded back n forth between wild stocks & FF fish over large areas. If I remember right they did some preliminary sea lice DNA testing some years back and that's what they found.
If one was out over the season, and over the years finding & collecting juvies over Queen Charlotte, Broughton and Johnston Straits (again assuming these people have been doing that) - one could also reasonably infer the most plausible migration route out of the watershed of origin to the capture location, and whether or not it was likely that this particular smolt would have encountered fish farms, and their plumes of farm-origin naupilar stages of lice.
The extent of those plumes are also well known - as Mike Foreman did extensive work years ago that DFO ignored & sat on because it was too embarrassing to admit:
Finite volume ocean circulation and particle tracking models are used to simulate water-borne transmission of infectious hematopoietic necrosis virus (IHNV) among Atlantic salmon (Salmo salar) farms in the Discovery Islands region of British Columbia, Canada. Historical simulations for April and...

In Scotland (Loch Shieldaig and Upper Loch Torridon) way back in 2004 - a sea lice plume modeling program (Gillibrand, Penston, McKibben, Hay, and others) was developed in conjunction with DFO Canada (Saucier et al.). See:
And in numerous other jurisdictions:
But NOT DFO. NOT TODAY IN 2025.
Sometimes, with large-enuff data sets where DNA is also sampled over the seasons/years- a very dependable pattern or nearshore habitat use and migration routes can be identified for some species and watersheds or origin - DESPITE the typical and expected BS from the DFO aquaculture bunch - because they don't want to shut the industry down doing what I am describing wrt DNA, habitat use & migration patterns.
Because that's how the moratorium on the North Coast was instituted:
Tyee Special Report. By Sarah K. Cox March 1, 2006 TheTyee.ca Strouts Point used to be just another rocky thumb of land along the Skeena River estuary's southern reach. Today, the once innocuous point is the snag in the salmon farming industry's contentious plan to expand to BC's North Coast.

Knowing the surface & near-surface water temps - and the stages of the sea lice - one could backtrack the approximate time/date that this fish got infested with any loading of lice. Knowing the likely migration route & rate- one could infer where/when it happened. Migration rates are fairly well known & documented - and could be proven & tracked using the DNA I was describing by collection site/date along that presumed migratory route.
The developmental rate of sea lice development is also well documented & known. The lifecycle of the parasitic copepod (
Lepeophtheirus salmonis) consists of 2 planktonic naupilus stages, 1 infective free-swimming copepodid stage, 4 attached chalimus stages, 2 mobile preadult stages, and 1 adult stage (Bjorn and Finstad 1997). Typical development time from egg to adult is 38 days at 10oC (Finstad 2002) – or 380 degree-days as thermal units.
So, all of this is do-able. But then comes the sticky part. How much lice is on which farm where. You saw the post above about:
B.C. salmon farms are pulling back lice reporting, raising risks for wild salmon and reducing public transparency.

I don't think these are unrelated events.
As I mentioned: Doubt is the commodity sold by the PR firms & the DFO comms branch - and they both get get paid to lie.
I don't think it is mere coincidence the data isn't available. These people running the show aren't stupid. And it is a show. A stupid show that we can't change the channel on.
