nothing like some nice Dungeness crab stir fried with green onion and ginger (chinese restaurant style). Yum yum. In San Francisco you can go crabbing and fishing on a public pier, but the dungenesses aren't allowed, they save those for the restaurants. You can take the black clawed ones though, not sure what those are called..
My dad likes to use fish heads and chicken carcasses for bait in a big round crabbing net.
