(Gymnosarda unicolor)

Commonly referred to as Dogies!

Growth

Dog tooth tuna can grow to a staggering 150kg in weight and measure well over 1.8 meters in length although most fish encountered around Australia average around  10 – 20kgs.

Tackle requirements

Medium to heavy lever drag trolling outfits or spinning combos are best suited for targeting dog tooth in most situations. Rods and reels capable of holding large capacities of  50 – 80lb line are most commonly used and are attached to wind on leaders of around 150 – 250lb in breaking strain. Larger fish respond better to deep live baiting or trolling techniques and require heavier stand up tackle in the 24 – 37kg range. Heavy wire leaders are necessary to prevent bite offs. Dog tooth over 100kg are rarely encountered by recreational anglers in Australia.

Recommended baits, lures and rigs

Live and fresh dead baits such as gar fish, mullet, flying fish and mackerel are all ideal baits for targeting large dog tooth tuna, with medium to large deep diving and bibless lures also proving to be quite effective on smaller specimens. Larger fish are generally taken in deeper , continental waters on deep trolled baits.

Handy hints and tips
