This a bit of a bitter pill to swallow but...........Ten Bears is correct.
I called Alaska F&G on Friday and spoke with fisheries biologist Tom DeCico(sp).
I asked him to settle the "bet" on this and his answer was straight forward. Biologically, genetically and behaviorally (and thus taxonomically) steelhead are more salmon than trout. He told me that there was some controversy about this in biology circles a few years ago but the research bore out the pro-salmon argument and drove the genus reclassification.
He told me further that the label "trout" is notional in so far as it is a european term for all fresh water fish that resemble salmon. European settlers recognized Atlantic Salmon and applied the term "trout" to all North American freshwater fishes that resembled that which they were already familiar with. Even the european Brown Trout is more salmon than trout. Mr DeCico told me that Atlantic Salmon are a sea-run strain of Browns and that genetically, the two are indistinguishable. He also said that for the purposes of technical accuracy, there are no trout, per se, in North America. Brookies, Dolly Varden (Bull Trout to you westerners) and Lake Trout are all species of char, not trout. Cutthroats including Goldens, are essentially the same as Rainbows/Steelhead insofar as being more salmon than trout.
So tradition ran afoul of science on this one, and I for one was sucked into pissin' match this by what I thought I knew. They'll always be trout to me no matter what they're called in Latin.
You win this one Ten, and I'm out of this thread.
