Nice video, man........There are several things to note in the video.
Firstly, for you newbie steelheaders out there, note the structure the two of them are behind, There are several large rocks on the stream bed which break up the current and allows them to rest. They do leave this area breifly, but soon return..If the water was not so clear, this is the spot you would want to fish during the earliet part of the season....
Secondly, I find it a bit amazing that these two fish are spawning in an area that has very little "cover"....They would surely be easy pickings for an eagle or mammal......When the female drops her eggs, as mentioned in the video, a large portion of the eggs go unfertilized and float down the river and are quickly devoured by the resident 'bows and cutty's.
If you were to check a few meters behind a pair of fish like this you would undoubtably see the little trout fighting over the eggs.....The few that do get fertilized have to endure the wrath of the weather, dry creek/river beds and a whole lot of hazards prior to hatching.
The caution on this post is to avoid wading in such areas, however, I submit there are very few fishers that would know where these areas are in any given river...Ortho
