Here in Southern California, vertical jigging is a technique we use for certain species when we want to reach them holding lower in the water column. The way we do it is a little different because of the style we employ (we call it yoyo fishing) and the conventional style fishing gear we use. When I see people do vertical jigging out on the East Coast or Asia, the style is fast and physical, and the fights look brutal on the spinning gear they use.
I’m not sure I’ll adopt this style anytime soon, but it fascinates the heck out of me. Check out this video from Salty Water Tackle where the angler is vertical jigging off New Guinea for tackle busting dogtooth tuna.
