Korean Rockfish
Sebastes schlegelii
Korea's shore-fishing staple, the black rockfish is a dusk-coloured ambusher of reef and tetrapod — modest in size, first-class on the table.

Where they live
How to catch them
Rock lure fishing Rock fishing
Rig: Light rock-game rod, small jig heads and soft plastics worked tight to the reef
Bait/lure: Small soft plastics, micro jigs
Key tip: Work the bait down the reef face at dusk; rockfish lunge from holes and vanish back into them.
Breakwater bait fishing Rock fishing
Rig: Float or light ledger rig dropped beside tetrapods and boulders
Bait/lure: Prawns, sandworms, small crabs
Key tip: Fish vertically into the gaps — that is where the fish live.
Boat fishing over reefs Boat
Rig: Boat rod with a down-shot or live-bait rig fished vertically over offshore reefs
Bait/lure: Live shrimp, sandworms or small soft plastics
Key tip: Drop straight onto the reef marks on the sounder; boat rockfish bite best on the first drop before the school scatters.
