- Black Kingfish US
- Ling US
- Lemonfish US
- Crabeater US
Identification
A muscular elongated tropical-coast pelagic predator — torpedo profile with a broad flattened head delivers brutal sustained runs. Juveniles slimmer than mature adults.
- Two narrow dark brown horizontal bands running snout to tail base
- Dark brown back grading to a silvery-white belly
- Broad flattened head with a slightly projecting lower jaw
- First dorsal composed of 7-9 short isolated spines with no connecting membrane
- Small embedded scales giving the body a smooth leathery texture
Where it holds
- Inshore
- Offshore
- Estuaries
- Mangroves
Behaviour
A solitary or loosely-paired structure-following pelagic predator working the upper 30m around floating debris, weed lines, channel markers, oil platforms, wrecks, buoys, and large marine animals (rays, sea turtles, sharks) that concentrate baitfish. Hunts by sight, cruising structure to ambush fish, crabs, eels, and squid. Most active at the surface in 22-30°C (72-86°F) water; coastal-migratory, moving inshore into bays and estuaries through summer and offshore as water cools.
Diet: Small Baitfish, Eels, Crabs, Shrimp, Squid
How it's caught
Line Fishing
Live Lining
The dominant SE US, Gulf, Mid-Atlantic, and Mexican Beach approach — sight-cast a live eel, blue crab, pinfish, finger mullet, or sardine on a 7/0-9/0 circle hook with 60-80lb fluorocarbon leader to fish cruising near the surface around rays, turtles, channel markers, weed lines, and platforms. Live eels are the signature bait — hook through the lower jaw or with a small treble behind the pectorals.
Jigging
A productive approach over offshore wrecks, reefs, and platforms — drop a 60-130g bucktail jig (chartreuse, orange, or pink with a rubber twister tail) or soft-plastic eel on a 4-6oz jig head and work it with large vertical sweeps and pauses. The eel imitation is the key cue. PE3-5 jigging tackle, 80lb fluorocarbon leader.
Spinning
An iconic Florida, Gulf, and Mid-Atlantic sight-cast approach — pitch a heavy 60-110g bucktail jig, soft-plastic swimbait, or tube lure ahead of visible fish cruising the surface and retrieve with sharp jerk-and-pause action mimicking a fleeing eel or wounded baitfish. 7-8ft heavy spinning rod, PE3-5 mainline, 30cm of 60-80lb fluorocarbon leader.
Spear Fishing
Bluewater Spearfishing
A premier bluewater spearo target — free-dive in clear blue water around floating debris, weed lines, and offshore structure. Cobia are naturally curious and follow rays, turtles, and sharks; they often approach divers closely. Aim for the head or spine on the first shot. 120-140cm gun with triple bands and 7.5-8.0mm shaft, breakaway rig with 400-500lb shooting line for the powerful runs.
Inshore Spearfishing
An accessible US East Coast and Gulf shore-and-jetty target during the late-spring inshore push — hunt around channel markers, wrecks, buoys, and stingrays in 3-20m. Approach calmly; the curious nature often lets divers get within shooting range. Float rig recommended for the strong runs even from smaller fish.
