Tackle requirements

Medium to heavy weight graphite rods in the 10 – 15kg range, around 6’ in length matched to spin reels in the 8000 – 10,000 class spooled with braided or gel spun lines with a breaking strain of 30 – 50lb are ideal for casting lures both from the shore and out in the boat for most trevally species including Diamond‘s. Trolling is also a popular technique and requires an overhead or spin combo spooled with 10 – 15kg brightly coloured nylon or braided line. Medium class lever drag reels and light rods are ideally suited for this exciting style of fishing. Diamond trevally do not have teeth but nylon or fluoro carbon leaders are generally required to provide some stretch when fishing with braided lines and also to prevent being rubbed off on rough under water structures.  Diamond trevally are also a fantastic target species for salt water fly out fits which should be rated to between 7# – 9# depending on the size of fish being targeted.

Recommended baits, lures and rigs

Live hardy heads, small mullet and whiting will all make great live baits for fussy trevally such as diamond‘s, try fishing them on long, nylon or fluoro carbon leaders and running sinker rigs. It is also important to match your hook size to your bait. Small to medium sized hard bodied lures are also ideal for both casting from shore and trolling from a boat at around 4 – 6 knots for many species including trevally with metal slices, soft plastics and fly’s also proving to be incredibly effective on this spectacular looking species.

Handy hints and tips

Wearing a casting glove prevents line cuts during long casting sessions.

Preferred fishing times and tides

Rising or full tides are best suited for targeting most inshore species including diamond trevally.
