Dogfish - not sure but from what I have read and heard from other fishermen, Steelhead can come to their nesting areas and stay in the rivers for several months before mating. Usually these fish are darker in color more resembling fresh water rainbows in coloring than the bright silver of 'fresh' fish. Anyone with different information???? Hope this helped.
