Went through your article Chris, and you have concisely covered the
reservations on salmonid cage culture as well as anyone I've read.
By the way, most of my working life was/ has been spent on aquaculture
research development in poorer societies, with a little initial work on
mollusc culture in this corner of the world. I got into it because (a)I saw
it as a way to reduce fishing pressure on wild stocks, and (b) it has
potential to feed hungry people.
So, a few sidebars from me:
n The food chain bit in your article is why I was never interested in
salmonid culture of any type. They are all carnivorous. Ya gotta catch
fish to feed fish, and that doesn't make environmental sense to me. We
should be eating those trash fish, not salmon. However, that isn't gonna
change unless we get a lot poorer.
n The corollary to this is that salmon are expensive to raise, so will
never be an important food for poor people.
n Personally, the presence of a couple of cages in an embayment doesn't
bother me, but the apparent ease with which such an operation can expand
many-fold and fast scares the hell out of me.
n Re. genetic contamination: (a) I always thought the idea of raising
Atlantic salmon on the west coast was a terrible one, because of the
potential for escape, reproduction, and competition with native species.
(b) I have heard the alarms raised about escapes of Atlantic salmon on this
coast and the potential to contaminate existing stocks, and am more
ambivalent here. Every species (and every population) evolves, through
natural selection on a genetically diverse population. If the genes of
escapees get introduced into a wild Atlantic Salmon stock, I kind of suspect
natural selection will operate, as usual. I have listened to the arguments,
but am still not very alarmed. I may be missing something, but personally
find there are plenty of more convincing arguments to raise cautions against
large-scale salmonid cage culture.
n To me, the scariest part of your article was the last bit, re. trade
agreements. I don't know the details, but don't governments have a
fundamental duty to protect our long-term interests?

Subject: [NatureNS] Down our throats: Fed-up with salmon feedlots
Hi folks,
The issue is as tangled as cage netting washed ashore after winter storms.
Forty years ago salmon aquaculture was seen as a burgeoning industry, a
salvation for fisherman, and a pathway towards a sustainable fishery that
would protect wild stocks. Salmon, once a rare treat for anglers and a
staple for many coastal native groups, was commodified into a mainstream
supermarket fish. Over time, however, flies began to appear in the ointment.
Thos concerned with this topic may be interested in my recent article on the
topic:
Down our throats: Fed-up with salmon feedlots

d-salmon-feedlots
Resolving the dilemmas posed by open-net salmon farming parallel the
necessity of resolving corporate exploitation of the environment, human and
natural. We need to find models of economic activity that are not in phase
mismatch with either the biological world or the human one. The failure to
do so will have critical consequences for both.
Best wishes,
Christopher Majka
