Saltwater · Spring and summer; sight-fishing peak as fish ride the surface in spring
Cobia
Rachycentron canadum
A powerful, brown, shark-shaped fish that cruises the surface around rays, buoys and wrecks and is mostly taken by sight-casting. Cobia eat jigs and live baits presented right in front of them.
Seasons · Peak
Identifying features
- Long, dark-brown body with a broad, flat, blunt head
- Dark horizontal stripe along the side, stronger on younger fish
- Short dorsal spines set in a depression, separate from the soft dorsal fin
- White belly and a slightly forked tail with a long lower lobe
- Look-alike: king mackerel is silvery and streamlined; cobia is dark brown with a wide, flat head
Habits
- Follows rays, sharks, turtles and boats, eating what they stir up
- Cruises near the surface on calm, sunny days in spring
- Often curious — will approach a boat and inspect a bait
- Migrates along the coast with warming water in spring
Distribution
Where to find them
- Channel markers, buoys and floating debris, checked by boat
- Behind large rays and over nearshore wrecks
- Beachfront bait pods within sight of shore in spring
- Sight-casting towers over shallow, clear flats edges
Where they live
How to catch them
Sight-casting jigs
Rig: 2-3 oz bucktail or soft eel on a heavy spinning rod, ready to cast
Bait/lure: Bright bucktails and dark eel imitations
Key tip: Lead the fish by several feet and work the jig across its nose.
Live bait at markers
Rig: Free-lined live bait on a 6/0-7/0 circle hook
Bait/lure: Live eels, pinfish or small crabs
Key tip: Check every buoy on the run — cobia hold within feet of the structure.
