Oyster Toadfish

Opsanus tau

A squat, big-headed bottom fish of Atlantic estuaries, famous for the male's foghorn 'boatwhistle' call. In late spring and summer the male guards eggs laid inside empty shells, cans and other hollow litter on the bottom. The Gulf toadfish is a close relative found further south.

How to catch them

Bottom baits tight to oyster reefs Shore

Rig: Simple bottom rig with a 1/0-3/0 hook and just enough weight to hold on oyster reef, pilings or rock

Bait/lure: Crab chunks or clam

Key tip: Fish it right against the structure — toadfish barely leave their shelter to feed, and expect snags on oyster bottom.

Dock bottom fishing (frequent bycatch) Shore

Rig: Small bottom rig with crab or shrimp chunks fished beside dock pilings while crabbing or general bottom fishing

Bait/lure: Shrimp or crab pieces

Key tip: Most dock toadfish arrive as bycatch — unhook with pliers and keep fingers clear of the strong jaws.

Best baits & lures

Crab chunksShrimp piecesClam or squid strips
