Question for you West coast guys.
Do Redside Rainbows and Steelhead share any watersheds?
If so do they interbreed?
Willi



The Redside, like the Golden were once Rainbows, but were
isolated and developed different coloration. They do not share
the same water with Steelhead or Rainbows. If they did they
would interbreed and return to the dominant strain which is
Rainbow.

I thought the Redside was your native Rainbow. How about this, do
Steelhead and nonmigratory Rainbows share the same watershed and do they
interbreed?

Yes, they do.

...and do they interbreed?

According to Robert Behnke in his excellent "Trout and Salmon of North
America," occasional interbreeding does occur. He goes on to say that
"Reproductive isolation, although not complete, must be sufficient to
maintain the integrity of the hereditary basis that separates steelhead and
resident rainbow trout."

Willi, I am sorry, I was speaking of the Redband Trout, not the
Redside Trout. The Redband is native to a few streams in
California.
