"Here in BC, as in other places were salmon are farmed, Atlantic salmon are
the most common species grown. Atlantics make up a little more than 80% of
total farmed salmon production in this province, with the remainder made up
of native Pacific salmon species (mainly Chinook and Coho)."

Ok. Looks like the resistance is to a fait accompli, thought there IS a lot of furor over farming Atlantic salmon ( apparently not
among the fish farmers though ) http://www-comm.pac.dfo-mpo.gc.ca/pu...icsalmon_e.htm
"When salmon farming began in BC during the late 1970s, three species of Pacific salmon were raised: chinook, coho and sockeye.
Farmers encountered a number of problems raising sockeye and coho salmon, including a low survival rate upon entry to sal****er,
stress leading to mortality or poor product quality, and slow and unpredictable growth. By this time, Atlantic salmon were already
being farmed in Washington State. BC salmon farmers began raising Atlantic salmon in the mid-1980s."

The point was that Pacific Salmon are also farmed which is not under dispute I hope.

Strong opposition to farmed fish, especially Atlantic salmon on the
west coast by State of Alaska and environmental group.

It should probably be noted that multiple attempts to establish the
Atlantic salmon on the west coast were made in the first half of the 20th
century. They all failed. The risk from escaped salmon would appear to
be negligible.

I'd like more information about those earlier attempts because local
opposition to sea based fish farms are claiming that Atlantic escapees
are already breeding in northern rivers.

Any ideas where to look ?

"Numerous attempts have been made in the 20th century by agencies on the
Pacific coast to introduce and establish Atlantic salmon. The most recent
attempt by WDFW was in 1981 when attempted introductions were made via
the release of cultured Atlantic salmon smolts. No adult Atlantic salmon
adults returned as a result of the releases. "

http://www.barbarycoastdivers.org/2002/08aug/p7.htm

"Indeed, a National Marine Fisheries Service report on "The Net Pen
Salmon Farming Industry in the Pacific Northwest," released last year,
classifies hybridization and colonization of Atlantic salmon in the
Pacific as having "little or no risk." The report notes decades of
aggressively attempted yet unsuccessful introduction of Atlantics as
sport fish. It quotes an estimate of one million Atlantic salmon escaped
from sea cages into Puget Sound and British Columbia since 1990 with no
evident attachment. It says that "few prey items of any sort have been
found in the stomach contents of escaped Atlantic salmon which have been
recaptured." In other words, the domesticated salmon, which are able to
live for months without eating, as are wild fish returning to spawn, have
thus far been unable to establish themselves in this ocean."
