While not "scientific" in the traditional sense of the word, thoughts and experiences from folks like Bob and others that spend day in and day out interacting with these fish and have been doing so for many years have to count for something.

In the absence of a formal study, their general impressions and comments on trends based on tangible experience is still real information. It is fair to say that none of us are completely without bias, but I trust Bob's breakdown of the big picture and don't he would screw facts for the sake of advancing a personal/professional agenda.

I am interested in Stam's question as well. The info we do have indicates that these early Duc fish are doing well, probably improving if not maintaining at decent levels compared to elsewhere. This is the typically negative effects of a broodstock/hatchery program. Why is that.
