Farm Tuna by planting Mackeral :)

Scientists at Tokyo University of Marine Science and Technology first extracted primordial germ cells from rainbow trout embryos.

These are cells which will, as the embryo develops, become testes or ovaries.

Then they put these cells into the peritoneal cavities of 60 developing masu salmon embryos.

When the salmon had grown to maturity and mated with each other, most of the offspring were trout-salmon hybrids which died quickly.

However, some were pure trout - an identity confirmed by genetic analysis.

"So my idea is, if we can make a small mackerel fish that can spawn tuna eggs and sperm, we can make marine ranching of tuna much easier and simpler."

Professor Yoshizaki also believes his technique could improve the chances of endangered species.

For example, masu salmon reproduce faster than rainbow trout, so if the trout were endangered, this approach could perhaps produce new inviduals more quickly than nature could manage.

I believe truth and principle do matter. If you have to sacrifice them to get the results you want, then the results aren't worth it.

That is another Interesting article. I wonder IF the Techniques used could also be Used with Mammels. Heh, The First thing I thought Of was that episode of the Simpsons. "Shark Boy".

Seriously though, I could Picture using this in Mammels for Getting Larger amounts of Endagered Spieces, and Even Raising the Surpluss of Certain Herd Animals that Have a higher Yield for Food.
