Good post Micro, lots to think about.. However, on item 1, I have to agree with others that you are wrong on that one. Studys have been done on Idaho fish that show that not only do steelhead return to the same river... they will return to the exact same Redd as they were born on in many cases. This would mean that there is a very good chance that they might meet up with sis for some lovin, and thats after 700 river miles from the ocean. Its one of the things I find totally amazing about these fish.
