Circle Hooks

Was wondering what kind of rigs you are running while trolling with ballyhoo for King Mackerel. I have maybe 50 rigs made up with single or double J hooks on the self.

Are circle hooks now required by law when using ballyhoo?
If so, can you still use a treble stinger hook while trolling and live lining?

Have not been King fishing in the past 18 months.

circle hooks are only required while natural baits (ballyhoo, mullet, spanish mackeral, etc)trolling when targeting billfish.
