The pens in British Columbia are Pacific Salmon, so both Atlantic and
Pacific are farmed. There is a lot of resistance to using Atlantic salmon
in
Pacific water, since you cannot eliminate escapes. Presumably the reverse
also holds true.


From http://www.salmonfarmers.org/library/farm.html

"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.
