Fresh wasabi... what a funny thing - I just came across mention of it being grown in BC. You may the whole article (http://community.livejournal.com/vancouver_eats/76702.html?#cutid1) on sustainable seafood and Vancouver restaurants interesting, but here's the part that mentions wasabi:
...the coho had been raised in land-locked Agassiz by scientist Bruce Swift, who employs closed tanks. And the fish waste, which in open-pen farming degrades the ocean bottom, is collected and used to fertilize other crops. In Swift’s case, it’s used to grow wasabi, which had been used in an earlier course to brighten the beef.
