Michael, I'm not accusing you of anything. I'm making conversation. I
don't interpret the NAS website the way you do. To me it provides facts
through observations and information sharing. What people do with that
information is the important thing.

Whirling disease came to North America (Pennsylvania) in the 1950s from
Europe via the food fish aquaculture industry, not the government. Private
and governmental aquaculture in North America has since been instrumental in
spreading the disease because hatchery conditions provide ideal conditions
for outbreaks-- weak stressed fish in high densities-- and the fish are then
transferred to other watersheds. Our native rainbow and cutthroat trout are
highly susceptible to Myxobolus cerebralis, the organism that causes
whirling disease. Brown trout are resistant to whirling disease in their
native Europe, just as in North America there are species of Myxobolus our
native fishes have resistance to.
