How to keep ragworm alive
Keeping ragworm in usable condition, and what follows for the water it came from.
Why keeping it alive matters
Ragworm are bought and dug for movement and scent, and both fade fast once they die. A live ragworm on a hook works in a way a dead one does not, and a bunch that has been allowed to go off will break up on the cast rather than staying on it. Ragworm are also expensive when bought, which makes keeping them properly a practical as well as a welfare matter.
The container
A shallow tray or box with the worms laid out rather than heaped. Depth is the enemy: ragworm crushed under the weight of the worms above them die and then foul everything around them. A single layer wrapped in newspaper, or laid in shallow trays, is the standard approach for a reason.
Temperature
Cool — the principle being fridge-cool rather than freezing, and never warm. Ragworm deteriorate quickly at room temperature and very quickly in a warm car. Because they come from cold intertidal sediment, cold is close to their normal condition and does them no harm; heat is what kills them.
Oxygen
Kept damp and cool in newspaper, ragworm need no aeration. Kept in seawater, they need it — a closed tub of standing seawater goes anoxic quickly and will kill a batch overnight. The damp-newspaper approach is generally preferred precisely because it removes the oxygen problem rather than managing it.
What to keep it in
Damp newspaper, or clean seawater changed regularly, but not a mixture of wet paper and standing water. The paper approach keeps them moist without immersing them; the water approach requires the water to be cold, clean and refreshed. Fresh water kills them — they are marine animals and tap water is lethal.
How long it keeps
Several days in good conditions, and considerably less if they are warm, heaped or sitting in stale water. Buy or dig for the session rather than for the month, and check them before each trip: a batch that smells strongly is already lost, whatever the calendar says.
Signs it is going wrong
Catching these early is the difference between losing a few and losing the lot.
- A strong ammonia or rotten smell, which means some have already died and are fouling the rest.
- Worms going limp, pale or breaking apart when lifted.
- Worms that no longer contract when touched.
- Discoloured or cloudy water if they are being kept wet.
- Fluid or slime pooling in the bottom of the tray.
Transporting it
In a cool box, laid flat in damp newspaper, out of the sun. The bank is usually warmer than storage, so keep the main stock in the cool box and take out only what is needed. Do not carry them in standing seawater in a warm vehicle — that combination goes bad faster than either alone.
What not to do
Each of these is a common and avoidable way of killing this bait.
- Do not put ragworm in fresh water, which kills them.
- Do not heap them in a deep container where the lower layers are crushed.
- Do not leave dead worms among live ones; sort them out at every opportunity.
- Do not seal them in standing seawater without changing it.
- Do not tip unused worms or their water into a different water body from the one they came from.
Biosecurity
Ragworm are marine animals dug from intertidal sediment, and both the worms and the water and sediment associated with them can carry organisms. Never tip bait water into a water body, and never move worms from one coast to another and release them. Digging also disturbs intertidal habitat directly, which is why collection is restricted or prohibited on many shores — filling holes back in and working over a spread area rather than a single patch reduces the damage.
Welfare
Ragworm are invertebrates and proportionate care means buying or digging for the session rather than in bulk, keeping them cool and uncrushed rather than slowly suffocating under their own weight, and not holding stock for long periods in conditions that are gradually deteriorating. Sorting dead worms out promptly is both the welfare measure and the practical one.
Unused bait
Return unused live ragworm to storage if they are still in good condition. Where they must be discarded, put them in household waste rather than into a water body — including the sea, if they were dug from a different shore. Do not empty bait water into any water.
Rules vary, and they vary a lot
Collecting, transporting, keeping and using live bait are regulated differently almost everywhere, and some of these baits may not be used at all in some waters. Restrictions commonly cover where and how much may be collected, whether live bait may be moved between waters, whether a species may be used as bait at all, and whether a licence or permit is required. FishingHQ does not state what any rule is or where it applies — check with the authority responsible for the water and the shore you intend to use before collecting or using live bait.
Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use

What this bait is for
The fish it catches, how it is fished and what you present it on.
Fish it catches
Black seabreamAn excellent bream bait, again used small and on small hooks.- DabInterchangeable with lugworm for dabs and often better where ragworm is the local worm.
European flounderThe near-universal flounder bait, because it is the thing the fish is already eating in quantity on intertidal mud.- Small-spotted catsharkWorm baits meant for flatfish are taken freely; the species is entirely undiscriminating.
Striped red mulletRagworm fished on the clean sand the fish probes with its barbels.
Tub gurnardWorm baits on clean ground take tub gurnards, particularly the smaller inshore fish.
European sea bassA fast, predatory inshore fish that hunts in broken water and surf, and one of the most closely managed recreational species in European seas.
