Ireland's most versatile bait
Ragworm is the most versatile bait in Irish shore fishing. Where lugworm is the specialist's choice for specific species, ragworm catches almost everything, bass, flounder, whiting, wrasse, pollack, mullet, sea trout and more. Every shore angler in Ireland should understand how to source, keep and use ragworm effectively.
Two species, which to use
King ragworm
Alitta virensThe larger of the two, reaching 30 to 50cm and occasionally much longer. Dark red-brown with visible legs along the body. King rag is the preferred bait for bass and smoothhound, the size and movement of a large king rag is irresistible to predatory fish. They have strong jaws and will bite, pinch just behind the head when threading onto a hook.
Harbour ragworm
Hediste diversicolorMuch smaller, typically 5 to 15cm, found in vast numbers in estuaries, mudflats and harbours. Red-brown with a distinctive iridescent sheen. Harbour rag is the go-to bait for flounder, mullet and smaller species. Used in bunches of three or four on a size 1 hook it is one of the most effective all-round shore baits available.
Sourcing and storage
Buying from tackle shops
Most Irish tackle shops stock both king and harbour rag, ordered fresh twice a week. Call ahead to check availability and order in advance if you need a specific quantity. Ask when the delivery came in, fresh ragworm within 48 hours is significantly more effective than older stock.
Digging your own
Harbour ragworm is abundant in muddy ground around Wicklow Harbour and the Vartry River mouth. Dig at low tide with a flat-tined fork. King ragworm is found in coarser sand and gravel in the lower intertidal zone near rock structures.
Storage at home
Store in the fridge (not the freezer) in damp newspaper or seaweed, never in water, which kills them rapidly. Change the newspaper daily. Keep at 5 to 8°C and use within three to four days of purchase.
How to hook ragworm
Threading (bass)
Push hook into worm's head, thread body up the shank, leaving 5 to 8cm of tail to wriggle freely
Bunch fishing (flounder)
Thread three or four harbour rag onto the hook, leaving all tails free, maximum scent and movement
Tipping
Add a small piece of ragworm to a lugworm or mackerel bait, a cocktail particularly effective for whiting
On a float (wrasse, mullet)
Thread harbour ragworm on a size 8 to 10 hook and fish beneath a small float close to structure
Best species for ragworm
Bass
King rag on a running ledger close to rock structure is one of the most effective bass baits from Irish shores, particularly in summer when bass are hunting actively.
Flounder
Harbour rag in a bunch consistently outperforms lugworm in sheltered harbour and estuary ground through autumn and winter.
Whiting
A tip of ragworm on black lug is the standard winter whiting bait on Wicklow beaches, the two baits complement each other.
Wrasse
Ragworm fished on a float or paternoster close to kelp and rock structure is an excellent wrasse bait from spring through autumn.
Mullet
Harbour rag on a size 8 hook with a small float is one of the few reliable mullet baits from Irish pier marks, use after groundbaiting with bread.
Key points
- 1King rag for bass and larger species, harbour rag for flounder, whiting and mullet

- 3Thread king rag from the head, leaving the tail to wriggle freely
- 4Bunch harbour rag three or four worms at a time for maximum effect
- 5Buy fresh, ragworm older than four days loses most of its effectiveness
