Question

Why are steel nose trout Endangered?

Answer 1

If you are asking about steelhead....(I assume so), they are sea run rainbow trout and are now considered members of the Pacific salmon group.  They are not endangered everywhere but in many streams they have been wiped out because of a lack of good spawning habitat or blockage of adult migration. Steelhead spawn in streams, the young live there a while, and then they migrate down to the ocean to live a couple of years (or more). They then move up from the ocean to spawn. Unlike other Pacific salmon, they don't die when they first spawn, but can do it several times.  Anything that interferes with their ability to move up or downstream or affects the eggs in the stream (pollution and sediment) can harm them and threaten their existance in any given stream.  These same problems are what threaten salmon everywhere.
