Todd- Thanks for the info. It is interesting to see that HxH fish become smolts but not adults makes a person wonder why. But I still don't see this study adressing the issue of HxW off spring breading with WxW or HxW adults and the subsequent survival rate of these fish. If survivial rate increases as the number of Wild genes are introduced over the generations then I see hope for the use of hatcheries in re-building wild stocks. If not then I will have no choice but to support the elimnation of hatcheirs as quickly as possible.
