The first thing I do when attempting to land one is get a rope around the tail. Hold on though, they don't appreciate it.

There are a number of ways to kill it, it's up to you, same as any fish.

I would kill it as quickly as possible, you may be dragging it back to the landing and that works best if it is dragged head first.

Clean it when you can, I prefer to let it sit in ice for a day, seems to work well for me.

I'm lazy so I put the steaks/fillets in a pan with butter and seasoning.
