Thanks Jim. I freely admit to having a biased and nearly empty mind on =
this subject. But despite these limitations am skeptical of rushing to =
judgment re farmed salmon when so many other factors might also be =
involved. It is bad form to burn the wrong witch.
I forgot to enter the author's name; Jessica Maxwell. When =
extracting a 14 page article much must be omitted. One interesting =
feature that I left out was the apparent effect of warmer sea water; =
salmon young become sluggish, mackerel move in and have a feast.
Yt, DW

Subject: [NatureNS] re West coast:Fw: Farmed Salmon
Interesting notes, Dave, and I'm responding off the top of my biased =
head from that West, namely central B.C. I am biased about open-net-pen =
salmon farming which is so wrong in so many ways. But I think we in the =
East have a lot to learn from the history and experiences of the =
salmon-farming industry in New Brunswick, about which we in Nova Scotia =
seldom hear much, even from CBC News and Maritime Noon etc. There is a =
lot of knowledge and expertise in the Conservation Council of New =
Brunswick, especially Inka Milewsky? who traveled to Shelburne in =
attempt to let the people in SW NS communities the on-going =
environmental effects of salmon feedlots. Also the history of the Inner =
Bay of Fundy Salmon should be somewhat instructive in the chronology of =
the sharp demise from 40,000 adults in various rivers in 1989? to less =
than 200 (100?) now. (Figures from a sign in Miner's Marsh in Kentville =
from the Atlantic Salmon Federation et al.) Finally, Jim Gourlay, who =
published the magazine Eastern Woods and Waters for a long time, is very =
knowledgeable about wild salmon as well as the history of salmon farming =
in the Bay of Fundy.
Cheers? from Jim in Burn's Lake, B.C.

Dear All, Nov 3, 2012
Further to my e-mail of June 9, I happened recently to run into =
an article about salmon on the West Coast (Natural History =
104(9):26-39,1995). At that time fluctuations over a 100+ year period =
seemed to be reasonably well explained by cyclical changes in weather, =
wind and ocean currents.
With respect to Chinook salmon on the west coast there was "...a =
period of sustained harvest from 1889 to 1920, the period from 1921 to =
1958 was one of sharp decline and from 1959 to the present we had a =
period of persistent salmon depletion."; page 31. On page 34 there is =
mention of a cool wet period from the 1960s to the 1980s when stocks =
briefly increased. 1920 to 1950 was a hot dry period; a time of sharp =
decline. Note from the 50s onward there was cumulative habitat =
degradation from logging.
In contrast, Salmon farming started in BC in the early 70s.
=
http://www.farmedanddangerous.org/solutions/industry-reform/history-in-bc=
/
Note that the period of steep decline over 37 years all took place =
before salmon farming started. And the period of modest increase was =
after farming started.
Perhaps, with respect to salmon farming, crap is not exclusively =
under salmon pens; some may be about salmon farming.

Subject: Farmed Salmon
Dear All, June 9, 2012
There has been numerous articles and letters recently about =
open-pen Salmon farms. One in particular caught my eye (June 9, CH, Jim =
Gourlay) "...proven devastation of wild Atlantic Salmon stocks wherever =
open-pen salmon aquaculture has been sited..."
As I recall, salmon stocks were in very bad shape before =
culture of salmon was initiated; culture of salmon being a way to offset =
the shortage of wild salmon and take some pressure off of these wild =
stocks that were probably being overfished off Greenland.
Are there really examples of abundant salmon stocks in areas =
where there has been no open-pen salmon farming ?
