Estuary Cobbler
Cnidoglanis macrocephalus
Estuary Cobbler (Cnidoglanis macrocephalus) is a large Australian sea catfish of estuaries, coastal lakes, and lower rivers. It is mostly nocturnal and bottom-oriented, taking crustaceans and small fish with venomous dorsal and pectoral spines.
Identification points
- Broad, flattened head with a wide mouth and prominent barbels
- Smooth, scaleless catfish body with a mottled brown to grey pattern
- Long dorsal fin and strong venomous pectoral spines
Habitat
Mud and sand bottoms in estuaries, tidal rivers, lagoon mouths, and sheltered coastal waters; often near snags, rock edges, drop-offs, and mangrove or seagrass margins.
Bait notes
Best on fresh baits such as prawns, squid strips, cut fish, mullet, or small crab pieces. Heavy-smelling baits work well at night and around slack tide.
Behavior
A nocturnal ambush feeder that rests on the bottom by day and forages at night. It uses sensitive barbels to locate prey and can handle brackish to fully marine water.
Caution
Venomous dorsal and pectoral spines can inflict very painful punctures; handle with extreme care and keep fingers clear of the spines. Notable for sharp spines rather than food-safety concerns.
Fishing notes
Fish the bottom with a sinker rig near deep holes, gutter mouths, snags, or channel edges. Use sturdy leader and long-handled dehooker; avoid lifting by the line because the spines are dangerous.
