I may not have a PhD, but I can read! And, I at least can honestly say… NO one is paying or providing me any funds to either publish or make statements, which are “half-truths”, “one-sided”, “tainted” and sometimes just downright “stupid”!

We will provide details on farm operations throughout the region to assist the inquiry in its determinations," the Salmon Farmers Association said in a release Thursday. "Claims have been made that salmon farms near Campbell River are having a negative effect on wild fish - especially sockeye. Sea lice on farmed salmon are monitored and managed to minimize possible transfer to wild populations. This work is audited by provincial authorities and is a condition of farm license.
I am very happy they will provide details especially Campbell River, since they will be required too? My “question”, is what information are they going to share and what information are they going to try to hide?

BCSFA said preliminary research shows that the common species of louse on sockeye (Caligus) is not the species normally found on farmed salmon which is Lepeophitheirus.
They may want to reconsider their research concerning Lepeophitheirus? I don’t think the Lepeophitheirus lice really care what species of salmon the find as a host! I do agree that commonly Sockeye are more prone to Caligus, but I have to challenge the statement (Caligus) is not normally found on farmed salmon, as indeed it is found and in “some” large number on their farm salmon! Or maybe they don’t consider 16.53 lice per fish – high? As stated and is correct the threshold is 3? To state (Caligus) is not a species normally found on farmed salmon… is ludicrous! They need to look at the July 09 lice count for Cyrus Rocks, but no need for “them” to worry, as you won’t find that information, as what I am referring to seems to have been removed from the Marine Harvest website… hmm, wonder why?

The sea louse, Lepeophtheirus salmonis, is commonly found on Pacific salmon that are rearing in the central North Pacific Ocean and adjacent seas (subarctic Pacific). Large numbers of sea lice have also been observed on all species of adult Pacific salmon when they return to coastal marine areas in the summer during their spawning migration. We propose that the transport of sea lice into coastal areas is a strategy employed by L. salmonis to improve their productivity by improving the transmission potential of the infectious stage when host densities are decreased in the open ocean and increased in the coastal areas. Juveniles of the species of Pacific salmon inhabit the same areas at the same time as the returning adult salmon and, according to the proposed strategy, will become infected from sea lice on the adult Pacific salmon. Juvenile pink, chum and sockeye salmon will carry these sea lice into the open ocean when they migrate away from the coastal areas later in the year. The offspring of these sea lice on pink, chum and sockeye would infect Pacific salmon on the high seas and thus maintain high abundances of sea lice. Juvenile coho and chinook salmon that remain in the coastal areas would serve as hosts for the sea lice over the winter. The sea lice on these resident coho and chinook salmon would infect juvenile Pacific salmon that enter the ocean in the early spring. The strategy would result in the infection of juvenile Pacific salmon throughout their range in all coastal areas.
Life cycle of Lepeophtheirus salmonis (order Copepoda), the so-called louse of salmons. 1, 2 Nauplius stages (0.54–0.85 mm), free swimming. 3 Copepodit stage (invasive stage, 0.7 mm). 4–7 Chalimus stages I–IV (1.2–2.8 mm long), engorging stages. 8a, 9a Preadult males – motile on skin. 8b, 9b Preadult females – motile on skin. 10a, 10b Adults (male 5 mm, female 10 mm). One generation needs about 6 weeks at a water temperature of 10–12°C.
The first two chart shows the actual lice count for Potts Bay, and Cyrus Rocks. The third chart is the migration route for the Strait of Georgia, fish farms are indicated by the yellow squares... And, they don’t think the farms are located in sensitive migration routes? I will gladly send them the last chart showing the salmon migration routes and fish farm locations, as they apprear not to have a clue!
