Chunking is the art of patience in offshore tuna fishing. By anchoring over productive bottom and creating a chum slick of cut baitfish, you draw tuna from miles around. When the bite develops, the action can be spectacular - multiple hookups on big yellowfin and bluefin. This technique has produced more giant tuna than any other method in New Jersey waters.

Overview
Chunking involves anchoring (or slow-drifting) over structure while dispensing a steady stream of cut butterfish or other bait. Fresh chunks sink through the water column, creating a scent trail that tuna follow to its source. Hooks baited with chunks are deployed at various depths, waiting for the tuna to arrive. Success requires patience, proper setup, and being ready when the bite happens.
When to Use This Technique
- ✓After trolling locates fish in an area
- ✓Over known structure and edges
- ✓When tuna are present but not hitting trolled lures
- ✓Night fishing for big yellowfin
- ✓When targeting giant bluefin
Step-by-Step Guide
Select and Set Your Spot
Choose your location based on structure, temperature, and recent reports. Anchor up-current of the target area so your slick drifts back over fish. In deep water, you'll need substantial anchor gear.
Tips
- •Mark the spot where you caught trolling fish
- •Temperature breaks and edges are prime
- •Use ball or drift sock to position without true anchor
Start the Slick
Begin cutting and tossing chunks immediately upon anchoring. Cut butterfish or bunker into 1-2 inch pieces. Toss a handful every minute or two - consistent but not wasteful. The slick needs time to develop.
Tips
- •Start chunking 30+ minutes before expecting fish
- •Vary chunk sizes to mimic natural variety
- •Keep chunks cold until use
Deploy Your Baits
Set lines at different depths - one shallow, one mid-depth, one deep. Use chunks on circle hooks with minimal hardware. Let baits drift back in the slick naturally. Watch rod tips for signs of interest.
Tips
- •Fluorocarbon leader in clear water
- •Circle hooks for better hookup and release rates
- •Stagger depths: 20, 50, 80+ feet
Watch and Wait
Chunking requires patience. Continue the slick consistently. Watch for signs of life - bait moving nervously, marks on the sounder, or the sudden disappearance of your chunks. When tuna arrive, things happen fast.
Tips
- •Keep electronics on to mark approaching fish
- •Watch the chunk sink rate - if they disappear fast, fish are present
- •Stay vigilant through slow periods
Manage the Bite
When a rod loads up, don't strike immediately with circle hooks - let the fish turn and the hook set itself. Coordinate multiple hookups carefully. Keep chunking through the bite to hold fish in the area.
Tips
- •With circle hooks, just come tight and reel
- •Clear other lines during multiple hookups if needed
- •Keep the slick going - stopping chunks ends the bite
Recommended Gear
Rods & Reels
30-50lb class stand-up rods
Medium-heavy for chunking. Sensitive tips to detect bites.
Lever drag conventional reels (30-50 class)
Smooth drag essential for long tuna runs.
Line & Terminal
50-80lb mono or braid
Match to reel capacity and target size.
60-100lb fluorocarbon leader
Invisible in clear offshore water. 6-15 feet.
7/0-9/0 circle hooks
Essential for chunking - corner hooks fish, reduces mortality.
Bait & Chum
Butterfish (fresh/frozen)
Premium chunk bait. Oily and irresistible to tuna.
Bunker
Alternative chunk bait. Larger pieces for big fish.
Cutting board and knife
Sharp knife and stable surface for constant cutting.

Best Locations in New Jersey
Hudson Canyon Edge
offshoreClassic chunking territory. Set up where the continental shelf drops off. Yellowfin and bigeye respond to well-placed slicks.
The Fingers
offshoreUnderwater ridges extending from the main canyons. Structure concentrates bait and tuna.
Offshore Lumps
offshoreHigh spots on the offshore bottom that attract life. Excellent chunking over these features.
Mud Hole Area
offshoreCloser location for giant bluefin. Fall chunking here has produced legendary catches.
Best Conditions
Tides
Current affects slick dispersion. Moderate current spreads your slick effectively. Too strong disperses it too quickly.
Weather
Calm conditions are ideal for maintaining position and working baits. Some chop is fine, but rough seas make anchoring difficult.
Time of Day
Chunking works day or night. Night fishing often produces bigger yellowfin. Dawn and dusk transitions can trigger bites.
Season
June through November. Peak yellowfin August-September. Giant bluefin October-November.
Common Mistakes to Avoid
- ✗Inconsistent chunking - the slick must be constant
- ✗Too much hardware - keep rigs simple and natural
- ✗Setting hook too hard with circle hooks
- ✗Stopping the chum when fish arrive
- ✗Improper depth coverage - fish different levels
- ✗Running out of bait too early
Pro Tips
- ✓Butterfish is worth the extra cost - tuna prefer them
- ✓Add a few larger chunks periodically for visual appeal
- ✓Night chunking with glow sticks on lines produces giants
- ✓Keep baits fresh - change every 15-20 minutes
- ✓Have live bait ready as a bonus offering
- ✓When the bite dies, reposition and start a new slick
Frequently Asked Questions
How much bait do I need for chunking?
Plan on 10-15 flats of butterfish for a full day. You can supplement with bunker. Running out of bait means the trip is over.
Do I need to anchor for chunking?
Traditional chunking involves anchoring, but you can also slow-drift over structure. Some boats use a 'sea anchor' to control drift speed while maintaining a slick.
What size tuna can I expect chunking?
Yellowfin average 40-80 pounds with fish over 100 possible. Giant bluefin exceeding 500 pounds have been taken chunking off New Jersey.
Can I chunk inshore?
Chunking works anywhere tuna are present. Inshore locations like the Mud Hole can be productive, especially for bluefin during migrations.
