Salmon Gives Birth To Trout.

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."

Had to say it....

...There's something fishy about this!

Good thing salmon die at spawning then

[SmallFurryCreature]

or there would be a lot of explaining to do by the moms.

Anyway wouldn't it be smarter the other way around? Last time I checked the menu salmon sells for a hell of lot less then trout.

Sounds like a Far Side comic.

This sounds like something out of a Far Side comic. Gary Larson would have had a field day with this. I can picture it already...

Sturgeon Farmers will watch this

[scupper]

Outfits like Sturgeon AquaFarms and Stolt Sea Farm will be watching this. I know US Sturgeon farmers have been pushing for a ban on Caspian Sea Beluga Sturgeon, and I think they are an endangered species. If there's going to be VC pushed into funding more cross species embryo research, I'd bet sturgeon farmers will be at the front of the line.

Excerpt from BBC piece:

"The obvious one is the sturgeon, which only become reproductively mature around the age of ten," he said, "so perhaps you could have them reared by another species which develops much faster."

Summary is DUMB, sensationalistic

[nusratt]

"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?

Ah, yes

Salmon do not give birth

[bill_of_wrongs]

they lay eggs like most other fish.

Mammoth

[memco]

Perhaps they can finally do http://www.exn.ca/mammoth/Cloning.cfmsomething similar with the mammoth? It'll be interesting to see how this technique develops.

They're the same species!

[Anonymous Freak]

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.

News Flash: Retriever gives birth to Terrier! :-p

Re:They're the same species!

[belmolis]

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

Oh man oh man

[tachyonmkg]

I can't wait until they make pigs that give birth to bald eagles or humpback whales that shoot pandas out of their vaginas.
