For those of you who do not keep up with all the latest salmon news, you may
be interested to know that Atlantic salmon have now been unquestionably
documented as successfully breeding in at least one Pacific Northwest stream
(Tsitika R., BC). Twelve juvenile salmon from two different year classes
were genetically analyzed to confirm the observation. If Atlantics are now
breeding in the Tsitika R., they are likely to be breeding in a number of
other coastal watersheds. We have the salmon farm industry to thank for this
unfortunate situation, which was predicted years ago (1980s) as a
consequence of development of Atlantic salmon farm in the Pacific Northwest.
This will undoubtedly add a new, confounding dimension to Pacific salmon
conservation and restoration.
