    Default Fussy salmon use genetic compatibility to pick mate!

    New findings by University of Otago researchers show that female salmon may influence the 'sperm-race' results from competing males and that there is a strong genetic basis to that female choice.

    Chinook salmon aren't the same as Atlantic salmon so let's hope that people don't believe this research is directly transferable.

    Not only that but, having read the paper, it's about in-vitro experiments, using an alien invasive translocated stock, from a hatchery or possibly domesticated stock.

    So now the scientists involved will be needing to broaden their research (need more funding) to work out what this actually means in the real world, with swirling currents, bullying 60lb cocks pushing competitors around, and sneaking fertile parr!

    Just how does the female exert "choice" in this case? Doesn't seem likely - "chance" would be dominant surely. If all the relatedness traits between hen and cock are met in the field the offspring may be better off (perhaps) but you'll only be able to measure it when their offspring's offspring return...

    What a waste of time. IMHO of course.
