Re: GM salmon (was triglycerides (was Carbs and physical activity)

[Guest guest]

I don't know about Atlantic salmon but the Coho and an other kind swim

up a stream not far from where I work, the girl salmon deposit their

eggs and the boy salmon, when they get there deposit their sperm and

it washes over the eggs. They are not duking it out for the right to do

so.

So I think this problem need some further thought. ine in

### I heard that GM Atlantic salmon had escaped in eastern Canada. I

think

the problem with the interbreeding thing is that the GM salmon are

bigger

and they may compete regarding breeding. Since they are bigger it's

believed that the GM salmon will win out against the smaller wild

salmon.

The problem is that those GM salmon are supposedly sterile. So there

won't

be enough fertile salmon to reproduce. I guess the sterile ones get all

the

action, but are shooting blanks. Yikes.

Hi ine:

I'm certainly not an expert on salmon, or fish for that matter, but I got

that information from http://www.pbs.org/wgbh/harvest/etc/video.html You

can watch a short video on it. It's been quite a while since I watched it,

so may have some details wrong, but the idea of problems with spawning is an

issue for GM fish. Of course I don't know how accurate PBS is either.
