Saltwater Jigging Guide: Depths, Jigs, Techniques
Vertical jigging for bottom and mid-water saltwater fish, with a focus on slow-pitch: centre- and rear-weighted jigs, jig weight by depth and current, thin braid and leaders, assist hooks, the slow-pitch and long-fall retrieves, staying vertical, and releasing deep fish with barotrauma.
Jigging means working a weighted lure up and down, and Wikipedia notes that most fish caught on jigs are on or near the bottom, with saltwater jigheads reaching nearly a pound for large groundfish. This guide focuses on slow-pitch jigging, a Japanese method, following a Hooked Up Magazine guide by an experienced Australian jig angler, plus Wikipedia and NOAA Fisheries for the basics and for releasing deep fish. The slow-pitch details are one angler’s method; we have not tested them ourselves. More species are in our saltwater fish section.
Vertical jigging basics (Wikipedia)
- The technique is mainly rapid lifts of the rod that pull the sinking lure upward, then letting it fall.
- You need a sensitive rod and constant contact with the lure.
- Because jigs are weighted, a harder-than-usual hookset is often needed.
What slow-pitch jigging is
The Hooked Up guide describes slow-pitch as presenting a slow-action jig with light line and small but powerful rods and reels, for bottom and mid-water fish, in slow or fast current, from about 20 to 500 metres. It notes greater amberjack and kingfish were among its original targets in Japan, and that almost any bottom fish that eats shrimp, squid, octopus or baitfish will take a slow jig.
Choosing jigs
- Centre-weighted jigs sink on their side with a swaying, shimmying action that draws strikes on the drop; best in slower current.
- Rear-weighted jigs have less action on the way down but get to the bottom faster, so they suit fast current.
- Weight by depth: as a rough rule, about one gram per metre of water when wind and current are low (a 50 g jig in 50 m), and up to double that in strong current or wind.
Rod, reel and line
- Rod: a true slow-pitch rod does most of the work: the tip folds over on each short crank of the reel and springs back, moving the jig. These rods have a parabolic action and are rated for a line class and jig weight.
- Reel: spinning or overhead both exist; the author prefers overhead because it lets you keep tension on the jig as it falls.
- Line: braid is a must, as thin as practical, so current and drift make less of a belly and you stay in contact with the jig. Braid that changes colour every 5 or 10 metres shows how far off the bottom the jig is.
- Leader: about 2 metres of fluorocarbon, roughly 10 pounds heavier than the braid but of similar diameter.
Assist hooks
Most slow jigs can take assist hooks at both ends, for hookups on the drop. Over heavy reef or kelp the author keeps hooks only at the top to avoid snags. He uses fine, very sharp assist hooks (finer than for fast, heavy jigging, because of the lighter line and drag) and at least two of them, so the second can take hold and share the load.
Retrieves
- Slow-pitch: no rod work; quarter or half turns of the reel make the rod fold and spring back, and the jig dances.
- Long fall: drop to the bottom, take up slack, lift the rod slowly to bring the jig a metre or two up, then lower the rod while staying just in contact as it sinks. After several lifts, wind up a metre or two and work that depth, then drop back.
- Stay on the bottom and vertical: the author calls the jig hitting the bottom and staying in vertical contact the two most important factors. Over sand, let the jig touch and stir the bottom; over reef, keep it just above to avoid snags. In deep water a bigger line belly means you may need more rod movement.
Reading depth and drift
- Use the sounder: drop to fish you mark on the screen; bumps and drop-offs are worth a drop. Our reading sonar guide covers the screen.
- Stay over the jig: reversing the boat into current or wind keeps you above it; if the line angle grows, wind up and drop again.
- Deep when calm: the author fishes deeper during slack water or the calmest part of the day and moves shallower as current or wind increases.
Releasing deep fish
Fish pulled up from deep water, such as grouper, can suffer barotrauma. NOAA Fisheries says the best way to help them survive is to release them as quickly as possible at depth, using recompression tools such as descender devices, release weights or release baskets. NOAA also advises handling fish as little as possible with wet hands and keeping air time under a minute. Check your state and federal rules, which may require specific gear in some fisheries.
