My apologies for addressing you as Tom, not sure why I did that sorry.

Here is a better link to Alexandras' blog concerning BC salmon and open
net pens.

> Hello Tom,

> for Food and Biotechnology, Gothenburg, Sweden, Knowledge Systems,
> Ecotrust, Portland, Oregon, and School of Food Engineering, Pontificia
> Universidad Catolica de Valparaiso, Valparaiso, Chile"
> Other than ecotrust they are all "food institutes" and "food engineering
> schools" in the heart of salmon farming regions of the world. The
> reference to land based production is the giveaway. Many scientists in BC

> changing fjords near the pens.
> I sincerely urge you to go to this scientists blog and read about what is
