Hardhead Catfish

Ariopsis felis

The ever-present sea catfish of Gulf piers, surf and bays — it finds almost any baited bottom hook. SAFETY: its serrated dorsal and pectoral spines carry slime and a mild venom and lock upright when the fish is handled; grip with great care or release it in the net, and never bare-hand the spines.

Identifying features

Smooth, scaleless grey-brown to olive body with a pale belly
Broad, blunt head armoured with a hard bony shield — the 'hardhead'
Six barbels: one long pair at the mouth corners, two pairs on the chin
Deeply forked tail and a tall, sail-less dorsal fin with NO long filament — the key split from gafftopsail
Serrated dorsal and pectoral spines that lock erect — handle with care

Habits

Bottom feeder on shrimp, crabs, small fish and almost any dead bait
Males mouthbrood the eggs and then the young through summer — a male with a full mouth is best released
Forms large schools in estuaries and along beaches in warm months
Constant bycatch on baited bottom hooks from piers, surf and bay boats
Spine wounds are painful from the serrations, slime and mild venom — clean any puncture promptly

How to catch them

Bottom rigs from piers, surf and bays Shore

Rig: Medium spinning rod, two-hook bottom rig or Carolina rig with a pyramid or egg sinker and 2/0-4/0 circle hooks baited with shrimp, squid or cut bait

Bait/lure: Shrimp, squid, cut bait

Key tip: Use circle hooks and pliers, and control the fish in a net — never reach across the erect dorsal and pectoral spines.

Estuary baited-hook fishing (the constant bycatch) Shore

Rig: Any baited bottom hook fished in estuaries, bayous and channels while targeting drum or seatrout — hardheads find it first

Bait/lure: Dead shrimp, cut bait

Key tip: Expect hardheads on nearly every bait; keep a dehooker handy and release them quickly without touching the spines.
