Oh.My.Gosh. "Ich". Have had a home aquarium guy forever. Got a few Ich infestations (always after introducing new, store-bought fish). Although not the same strain (tropical usually is Ichthyophthirius Multifiliis). Sounds pretty much like the same infection progression. Me, and every other tropical aquarium enthusiast, HATES Ich. Now doubly so given a favorable opinion of wild salmon.

What happens when you get Ich in an aquarium: While tendrils start to show up then lengthen on your fish. You try a few treatments, but by the time you see it it cannot be stopped easily. When your fish are covered by pretty long white "shite" strands, they start to die. Worse than any horror film you might have seen. Man do I hate Ich.

"Chinook in the Yukon River appear to be particularly vulnerable to a common parasite—and warming waters may be abetting the infection"
