I can relate to both sides of this arguement.
When I was a kid, my grandparents lived on the south sound and I LOVED visiting them because I could go clamming, crabbing, and fishing just down the street. Everytime I would come back with something unusual I would find (moon snail, 'eel', squid, geoducks(sp?)etc) and my grandpa would know a way to cook it up so that it tasted great! I learned to love seafood and saltwater fishing this way.
I guess my thinking is that the damage by bottom trawlers, over harvesting (targeted or not), and pollution has so much more impact on these animals than the occasional - "hmmm, this may be good eating". And it's the guys that are out on the water regularly that don't respect it that need to be careful. How many of us have ever sliced up a dog fish we caught while mooching? Some day, we may be wishing we could "at least catch a dogfish!".
So what's my point? (I'm confusing myself more as I go
We should be worried less about a few curious people who want to try something new, and more worried about the fishman who target these species as food every day, or other commercial/environmental (etc) impacts that have wiped out the animal life in the sound...
I guess I am agreeing with both sides: the octopus - try it, you may like it. But next time, it would probably be best all around to just let the thing go...
(I think it's time to go home, I'm not sure I made an ounce of sense...)
