Generally "red" salmon is wild caught while "pink" salmon is farm-raised. Usually farm-raised is higher in omega 3's since the farmers try to boost it with a diet higher in omega-3s than is available to wild salmon.
And just for thoroughness, I'll through in a short article from the vet school at WSU on salmon poisoning disease.
I never fed fish when I was raw, so I can't say much, but good luck on that car trip!
Some more fishy information that I wrote on another thread. Call me lazy.
