Secondly, my problem with this particular case of genetic engineering is
that these "Atlantic salmon" with the attributes described below pose a
major threat to what's left of native Atlantic salmon in North America. The
transgenic fish grow faster and can reproduce at a smaller size. Other
things being equal, this means that they will be more successful in
reproduction, leave more descendants, and thus swamp the gene pool with
their non-necessarily well-adapted genes for life at sea and in rivers. This
last point is important; there's evidence that each individual river-run of
salmon is micro-adapted in its genetic composition for maximal survival in a
given river, and making it out to sea and back. A sudden infusion of
essentially random genes in a given river population (stock) will
destabilize this genetic adaptation and probably lead to a stock collapse.
Maybe even worse, these genetically altered fish could be wildly successful
and become a new kind of weed. What would this mean?--who knows? That's the
