Scaly mackerel are small, fast-moving baitfish that turn up in big schools and keep the whole food chain firing. Most anglers don’t chase them as a trophy fish, but they’re handy for live bait, fresh strip baits, and finding where the predators are working.
In Australian waters they’re mostly seen up north, especially around tropical and subtropical coasts of Queensland and the Top End. They hang around inshore bays, harbours, river mouths and near headlands, usually in surface to mid-water schools where there’s plenty of current and bait activity.
They feed mainly on tiny plankton and other small bits in the water column, cruising in schools and filtering food as they move. When the water is alive with bait and current, they stay active and can stack up thick in patches.
Tide-wise, a bit of run usually helps because it pushes food through and keeps schools moving, while dead slack water can slow them right down. Low light around first light and late afternoon often has them higher in the water and easier to find, though they can stay active through the day if the bait is there. Light to moderate wind can help by stirring up surface food and current lines, but strong wind makes them harder to spot and harder to fish cleanly. Small to moderate swell is usually fine along open coasts, but once it gets too lumpy the schools can spread out or shift into more protected water.
A tiny bait jig, sabiki rig or very small long-shank hooks under a float works well if you want to catch a few for bait. Use light line, small bits of pilchard or prawn, and keep an eye out for flicking surface schools, birds and bust-ups.
Big schools of scaly mackerel often act like a dinner bell, so if you find them, bigger pelagics usually won’t be far away.
