Cobia
Rachycentron canadum
Cobia is a fast-growing, warm-water pelagic fish found in coastal seas, often around reefs, wrecks, buoys, and channel markers. It is prized by anglers for powerful runs and strong table quality, but it can carry ciguatera risk in some tropical waters.
Identification points
- Long, torpedo-shaped body with a broad, flattened head
- Dark brown back with a distinct pale lateral stripe from eye to tail
- Small first dorsal fin followed by a long low dorsal fin extending most of the back
Habitat
Nearshore and offshore warm-temperate to tropical waters; commonly around reefs, wrecks, oil rigs, buoys, pilings, floating debris, and occasionally in bays and estuaries during migration.
Bait notes
Live eels, pinfish, mullet, menhaden, sardines, blue runners, crabs, and squid are top baits. Large bucktail jigs, swimbaits, and slow-trolled lures also work, especially around structure.
Behavior
Solitary or in small groups; often shadows rays, sharks, turtles, and large structure. It feeds on crabs, squid, baitfish, and eels, striking hard and making long, stubborn runs.
Caution
Can cause ciguatera poisoning in some tropical/subtropical areas; avoid eating large fish from known risk zones. Strong runs can foul lines around structure, and handling a thrashing cobia can be hazardous.
Fishing notes
Sight-fish or chum them near markers and structure; cast ahead of cruising fish and let baits swim naturally. When fish are around wrecks or rigs, use strong tackle and steady pressure to keep them from breaking off.
