Salmon rigging - anchovie

Attached is a pic from a recent charter. You can see the anchovie has a barbless circle hook with some kind of wire coming out the mouth with a rubber band and a pin to hold in place.  I've searched all over for a place to order this setup.  Can't find it anywhere, any ideas?

It looks home made like a wire attach to the hook.doesn't look to hard to make

Those are "cable baiter" hooks.

They are available at most fishing stores in the bay area and online. Here are a few examples of them:

That's not a circle hook

Are these legal for ocean/bay salmon?

I hunted hi and lo, found some rhonert park fishing shop.  Comes with a copper wire and needle, what the heck is that for?

Commercial fisherman used to call those hooks crowbars in that a fish could use the length to lever it out of the mouth occasionally. The alternatives were cable baiters and easy baiter blades. Siwash hooks were crimped onto the blade making it more difficult for a salmon to dislodge the hook. The blade system does not work well for chovies because of the chovie mouth shape. The pin in the pic goes through the chovie head and hole in the top of hook and the wire wraps it and head around to secure the bait to the hook.

and, these are for trolling only.  For mooching or drifting bait, you have to use circle hooks.
