Salmon Gives Birth To Trout.

Posted by timothy on from the paper-contains-facts dept.

mishmash writes "Researchers in Japan have created trout whose fathers were salmon, 'they implanted tissue from trout embryos into salmon embryos; and when the salmon became adults and mated, they produced trout.' Jurrassic Park just came a step closer. The story is also at Nature, where the scientists actually discuss using the technology for reviving extinct species."

    "Jurrassic Park just came a step closer."

    Oh, really?
    The Nature article clearly says at the beginning:
    "The technique involves cells called primordial germ cells (PGCs), which are found in embryos."
    And later:
    "theoretically, even if a species **goes** extinct, we can transplant the cells into a closely related species."

    Where is John Hammond (JPark founder) going to get dino *embryos*?

    And, OTOH, if the "some day" merely refers to using DNA (versus PGCs), then how is this news?

    they lay eggs like most other fish.

  3. They're the same species! by Anonymous+Freak · · Score: 3, Informative

    Salmon and Trout are the same species, just different subspecies. Is this really surprising? (In fact, Steelhead Salmon is the exact same fish as Rainbow Trout. The only difference is that Steelhead swim to the ocean, Rainbow Trout stay in rivers. Really. http://www.aps.uoguelph.ca/~ontaqua/name.html

    This is about as surprising as a Calico cat giving birth to a Siamese cat. Extremely unusual, but not a huge deal.

    Oh, I see. The story talks about DIFFERENT species. Well, then call them by their full names. Just saying "salmon" and "trout" doesn't say much.

      According to the Nature article, the trout concerned is Oncorhynchus mykiss. The salmon is Oncorhynchus masou. Same genus, different species.
