Overview

Shark mackerel are common around northern headlands, islands and reef edges and will eat almost anything moving quickly.

They have very soft, oily flesh with a distinctive ammonia smell — it can be eaten if bled and skinned immediately but most anglers use them for bait or release them.

They frequently spoil a session by shredding leaders intended for other pelagics.

Where to find them

  • Rocky headlands and island points in tidal flow.
  • Shallow tropical reef edges after dark.
  • Around anchored boats with a berley trail.
  • Bait schools holding tight to structure.

Tackle

  • Rod: 7' spin rated 8–15 kg.
  • Line: 30 lb braid with wire bite trace.
  • Lures: chrome slugs, surface poppers, whole gar or mullet.

Tips from the water

  • Use wire — they will bite through anything else.
  • Handle carefully; their teeth and slime are unpleasant.
  • Excellent strip bait for reds and Spanish mackerel.

Regulations

Size, bag and possession limits differ between states and can change each season. Check the current rules with your state fisheries authority before keeping a fish.
