Seafood off the boat is a 100% cash business. It’s really easy to launder through it. Wouldn’t be a big deal to have planes dropping crab traps and lobster pots of merchandise. It’s a huge felony to pull someone else’s trap. And of course you could smuggle people by boat, as well.
I've seen past references to child trafficking going on at Fisherman's Wharf. No idea if that's related. But, there are rumors.
Apparently, there is a huge maze of tunnels under the Presidio, an old military base in SF used for trafficking: https://greatruns.com/wp-content/uploads/2016/11/SanFran4.jpg
