Sea Fishing Bait: The Complete UK Guide
By Alex Clayton · Updated 24 October 2026
The best bait for sea fishing in the UK comes down to five baits: ragworm, lugworm, mackerel, squid and peeler crab. Between them they cover most shore and boat fishing around the coast. Match the bait to the species, the ground and the season, and keep it fresh, because a little good bait beats a big bag of tired bait.
If you only buy one thing for a first general session, buy worms. Rag and lug are the most widely used sea fishing bait in the UK, and tackle shops stock them all year.
This guide covers the core baits, which fish each one is for, how ground and season change the choice, buying and storage, presentation, and the rules on collecting your own. For freshwater baits too, see our full bait guides.
The Five Baits That Catch Most UK Sea Fish
Ragworm and blow lugworm on their own are the most commonly used sea baits in the UK, and tackle shops generally stock them all year. Add mackerel, squid and peeler crab and you have a bait box that covers most species you will meet from a UK beach, pier or boat.
Lugworm
Lug is a sand and mud bait, and a favourite for cod and flatfish. Fresh lug is juicy and full of scent, but it bursts easily on the cast. Firmer lug, dried off or wrapped, survives a longer cast. Our guide to lugworm as bait covers digging, buying and hooking it.
Ragworm
Ragworm suits mixed sand and rock, where baits get dragged and picked at. It is a go-to for flatfish and also takes wrasse. See our full guide to ragworm.
Mackerel
Mackerel is oily and firm enough to stay on the hook through a hard cast. In summer you can catch your own on feathers. Otherwise, buy it from a fishmonger or supermarket. Our mackerel bait guide covers cutting and rigging it.
Squid
Squid has firm white flesh that stands up to casting. Use thin strips for small species and whole squid for cod, big bass and conger. Our squid bait guide covers which type to buy.
Peeler Crab
Peeler crab is a crab about to shed its shell, and it is a top bait for bass and smoothhound. It only works while the shell is soft, and tackle shops stock it sporadically, so ring ahead. Our peeler crab guide explains how to spot and prepare one.
| Bait | Best ground | Main targets | Stays on when cast? |
|---|---|---|---|
| Lugworm | Sand, mud | Cod, flatfish | Soft (fresh) to medium (firmed) |
| Ragworm | Mixed sand and rock | Flatfish, wrasse | Medium |
| Mackerel | Most ground | Rays, bass, conger | Strong |
| Squid | Most ground | Cod, bass, conger | Strong |
| Peeler crab | Estuary, rock | Bass, smoothhound | Medium (bound) |
Useful extras are sandeel (bass, rays, pollack), herring, bluey (Pacific saury), raw prawns, mussel and razorfish.
For one mixed session, take rag plus a pack of frozen mackerel or squid.
Best Bait for Sea Fishing by Species
The best bait for sea fishing is the one your target fish wants, and fishing one bait for everything is a common route to a blank. This table starts from the fish, not the bait.
| Species | First-choice baits | Also worth trying |
|---|---|---|
| Cod | Lugworm, squid | Lug and squid cocktail, whole squid for big fish, raw prawn |
| Bass | Sandeel, peeler crab | Whole squid for big bass, mackerel |
| Whiting | Fish strip | Raw prawn |
| Flounder, plaice, dab | Ragworm, lugworm | Ragworm tipped with mackerel, prawn, earthworm for flounder in estuaries |
| Rays | Sandeel | Mackerel |
| Smoothhound | Peeler crab | Hard crab |
| Wrasse | Hard crab | Worm |
| Conger | Whole squid | Mackerel |
| Pollack | Sandeel | |
| Mullet | Bread | Maggots, ham |
Treat this as general guidance from established bait guides and the angling press, not a rule. A bait that works on one beach can be second best on the next, so ask the nearest tackle shop what has been catching that week.
Two entries surprise people. Mullet ignore most sea baits and take the bread and maggots a coarse angler would use. Flounder pushing up estuaries will take an ordinary earthworm.
Sandeel and crab keep appearing for the predators, and worm for the bottom feeders. If you are unsure what a mark holds, put a worm bait on one hook and a fish or squid bait on the other, and let the fish choose.
The two species most anglers chase get their own pages: choosing bait for bass and the best cod baits.
The quick contrast: cod respond to bulk and scent, so big worm and squid baits work well. Bass are often more selective, and natural food such as peeler crab or sandeel is the usual first choice.
Bait by Ground and Season
Why does a bait that worked on a sandy beach in summer do so little off a rocky mark in winter? Because what the fish eat changes with the seabed under them and with the time of year.
Ground
| Ground | Baits that suit it |
|---|---|
| Open sand and surf beaches | Lugworm, sandeel, razorfish and mussel after storms |
| Mixed sand and rock | Ragworm |
| Rock and kelp | Hard crab (for wrasse), ragworm |
| Estuary mud | Lugworm, ragworm, peeler crab, earthworm for flounder |
| Piers and harbours | A mixed bag, so carry worm plus a fish bait |
Razorfish and mussel earn their place after a storm, when waves have broken beds open and fish are feeding on what has been washed out. On mixed ground, ragworm survives being dragged over stones better than soft lug.
Season
This is general guidance from the angling press rather than fixed rules, so check with a local tackle shop.
- Summer: mackerel are easy to feather and as fresh as bait gets. Peeler crab is at its best when crabs are moulting, though supply varies from shop to shop.
- Autumn and winter: squid comes into its own, and big lug and squid cocktails are a standard approach for cod and whiting.
- All year: rag and lug are always worth carrying.
For the methods that go with these baits, see our sea fishing techniques.
Best for: anglers trying a new mark, who should read the ground first and the calendar second. Skip if you fish one venue all the time and already know what it responds to.
Fresh, Frozen or Preserved: Buying and Keeping Sea Bait
Worms are easy to buy and easy to present, but they cost more than frozen bait and they don’t keep. Buy too many and half the box goes in the bin.
Fresh
Worms and peeler crab are the main fresh baits. Buy them as close to the session as you can and keep them cool and damp, not wet and not warm. A cool bag in the car does more for bait than any trick. Check worms before you set off and remove any dead ones, because they quickly taint the rest.
Frozen
Mackerel, squid, sandeel, bluey and herring all freeze and travel well, which makes them the backbone of a bait freezer. Peeler crab can be frozen too. If you buy prawns, use raw ones, not cooked.
Squid is one place where anglers argue. Many prefer unwashed loligo squid to washed calamari-grade squid, because they believe washing removes scent. That is a widely held belief rather than a tested fact, so treat it as a preference, not a rule.
Preserved
Shelf-stable preserved baits are worth a place in the tackle box as an emergency backup for when the shop is shut. They are not a main bait.
| Fresh | Frozen | Preserved | |
|---|---|---|---|
| Scent | Strongest | Good | Weakest |
| Cost and waste | Highest, spoils fast | Moderate, keeps in the freezer | Low, keeps longest |
| Convenience | Buy on the day | Ready when you are | Always to hand |
The verdict: carry fresh as your main bait and keep a frozen pack as insurance.
Presentation: Bait Size, Cocktails and Surviving the Cast
The cheapest edge in sea fishing is a fresh bait on every cast. Never recast a bait that has already been fished, because the scent has washed out of it. That matters most at night, when fish find food by scent trail.
Match the bait to the mouth
Small strips and small worm baits suit small species such as whiting and flatfish. Whole squid and big cocktails are for cod, conger and big bass. A bait too big for the fish in front of you gets pecked to nothing without a proper bite. When bites are fast and shy, scale down. When small fish and crabs strip the hook before anything better arrives, scale up and switch to a tougher bait such as squid.
Cocktails
Two baits on one rig can outfish either alone. Two classic examples:
- Lugworm and squid on pennell hooks for cod.
- Ragworm tipped with a strip of mackerel for flatfish.
Shellfish such as cockles, winkles and whelks are mainly used to bulk out cocktails rather than as baits on their own.
Surviving the cast
Firm baits such as mackerel, squid and firmed-up lug stay on the hook better than soft ones. For soft baits like fresh lug and peeler crab, anglers widely use bait elastic, wrapped round the bait to hold it together on the cast.
If your baits keep flying off, firm them up or bind them before you try casting harder.
Collecting Your Own Bait: What the Rules Say
Bait digging is one of the activities GOV.UK names as restrictable at protected sites under Special Nature Conservation Orders, alongside off-road driving and bonfires. Consent for restricted activities comes from Natural England in England or Natural Resources Wales in Wales.
The same GOV.UK page gives two examples:
- An order restricting bait digging at Lindisfarne, made on 15 October 1993.
- An order at Portsmouth Harbour restricting large-scale commercial bait digging, made on 18 January 2001.
That doesn’t mean digging is banned everywhere, only that specific sites can restrict it.
Local byelaws. In England, check the byelaws of your local Inshore Fisheries and Conservation Authority (IFCA) before you collect bait. Rules differ from district to district.
Etiquette. Backfill holes, put rocks back the way you found them, and take only what you need.
Licences. GOV.UK’s rod licence page covers fishing for salmon, trout, freshwater fish, smelt or eel in England (except the River Tweed) and Wales. It doesn’t mention sea fishing, so check the current position on GOV.UK and read our fishing licence guide.
Bass. Before keeping bass, check the current recreational rules on GOV.UK. The 2026 bass guidance applies from 1 January 2026, and our bass fishing regulations page explains where to look.
The GOV.UK points above cover England and Wales. Scotland and Northern Ireland have their own rules, so check with the relevant authority before you dig.
Frequently asked questions
What is the best all-round bait for sea fishing in the UK?
Ragworm or lugworm. They are the most widely used UK sea baits, tackle shops stock them all year, and they catch everything from flatfish to cod. Take a frozen pack of mackerel or squid as a backup, so you have a firm bait for bigger fish and for days when the worms run out.
Can I use supermarket fish as sea fishing bait?
Yes. Mackerel from a supermarket or fishmonger makes good bait, and it is oily and firm enough to cast well. Raw prawns from the fish counter work for cod, whiting and flatfish. Use raw prawns, not cooked ones.
Is frozen bait as good as fresh?
Not quite, but it is reliable. Frozen bait usually gives off a little less scent than fresh, yet mackerel, squid and sandeel freeze well and catch plenty of fish. Peeler crab can be frozen too. The best sea fishing bait plan for most anglers is fresh worm as the main bait with frozen fish or squid as insurance.
Can I dig my own bait anywhere?
No. Bait digging can be restricted at protected sites under Special Nature Conservation Orders, according to GOV.UK, and in England local IFCA byelaws can also apply. Check the rules for the beach before you dig. The rules section on this page has the full breakdown.
Do I need a licence to collect bait or sea fish?
Check GOV.UK before you go. Its rod licence page covers salmon, trout, freshwater fish, smelt and eel in England (except the River Tweed) and Wales, and it does not address sea fishing or bait collection. Collecting bait can still be restricted at protected sites and by local byelaws. Our fishing licence guide explains the current position in more detail.
