Most cod specialists use relatively heavy tackle. Line breaking strains in the 40 to 50 lb or even higher are common amongst those aiming for the larger fish. The new super braided lines have proven useful, especially when trolling in heavy cover, which is where you find the fish. Cod respond well to large baits and lures. Many cod specialists fish only large trolled or cast deep diving lures with a wide action at dead slow speed.
Surface lures work well at night and large flies have been tried with success.
Bardi grubs, Yabbies , shrimps and scrub worms all catch cod. If using fly, you need heavy gear, as cod can pull like a steam train. Even small cod will take very large baits and lures, and give you a run for your money to boot. Size and bag limits and closed seasons apply in all States where Murray cod occur, so check your local regulations. NFA strongly encourages you to practice catch and release when fishing for Murray cod, especially with large fish which are important breeding stock for the species and which are less palatable in any case.
