Atlantic cod

Straight answers

For somebody who is already standing on the mark. Everything below this expands on it.

When should I go?

In Britain and Ireland, from the first autumn gale onwards — roughly October to February, and the days immediately after a big sea are the ones worth taking off work. In northern Norway, January to April, which is the opposite half of the year.

Where should I stand?

Where a rough sea has been putting food. A beach with rough ground at one end, the tide line of a storm, a gully in a rock mark, the scour off a pier stanchion. Cod come inshore to eat what the sea has dislodged.

How far do I need to cast?

Usually far less far than you think. Coloured water brings cod into the first gutter, and a great many winter cod are caught inside forty yards by people who watched somebody else cast a hundred and blank.

What bait?

Big, and more than one thing. A lugworm-and-squid cocktail is the default because it covers two of the prey types cod specialise on; a peeler crab covers a third. Find out what the local fish are eating rather than deciding in the shop.

Can I keep it?

There is no UK recreational bag limit for cod as at 2026, and minimum sizes are set district by district in England rather than nationally. Check your own IFCA or administration before you fish, not after.

  How this mark actually fishes

  Why fish are here

  A steep-shingle or mixed-sand beach after a blow is a food conveyor. Broken shellfish, dislodged worm and crab, and weed all end up rolling in the coloured water inside the first or second bank, and cod come into extraordinarily shallow water to feed on it under cover of colour and darkness. The gutters — the troughs between banks, visible at low water on a spring tide and invisible at any other time — are where the food and the fish both end up.

  How to fish it

  Fish the gutter, not the horizon. On a coloured winter sea a hundred-yard cast frequently lands beyond the fish; forty to sixty yards into the first trough will out-fish it, and there are evenings when a bait dropped into the second wave is the one that goes. Use a grip lead heavy enough to stay where you put it, because a bait rolling in the sweep is a bait that has left the feature. Two rods if the venue allows: one short into the gutter, one long onto the outer bank, and let the fish tell you which.

  What to look at on arrival

  • Weed on the tide line and brown water. Both mean the sea has been working.
  • A dropping swell rather than a rising one. Rising means it is about to become unfishable.
  • Slack bites that pull the lead out of the sand rather than rattling the tip — a cod frequently moves towards you.

  What goes wrong here

  • Casting as far as possible on principle. On a coloured winter beach this is the single commonest way to fish past cod.
  • Fishing a beach you have never seen at low water, which means fishing without knowing where the gutters are.

  The conditions that make winter beach cod fishing good are the conditions that drown people. A big dropping sea still puts unpredictable waves up a shingle bank, and cold water plus dark plus alone is the combination behind most shore fishing fatalities.

• Rock marks

  Depth close in, and the edge fish hunt along

  Rough ground, where the food lives and the tackle dies

  • On or near the bottom
  • Deep water

  Methods: Ledgering, Surfcasting

  How this mark actually fishes

  Why fish are here

  Boulder fields, kelp and broken reef hold the crustaceans, small fish and shellfish that cod eat, and they hold them permanently rather than only after a storm. A rock mark with deep water close in gives a cod the two things it wants at once: food, and enough depth to feed in daylight. These marks frequently fish when beaches do not, because the food does not have to be delivered by a gale.

  How to fish it

  Accept that you will lose tackle and set up so that losing it is cheap and safe: a rotten-bottom link so the lead goes and the fish does not, and line heavy enough to pull a hook out of kelp. Fish shorter than you would on sand — the gullies close in are the feature. Bait big and tough, because everything on rough ground will strip a soft worm bait in minutes.

  What to look at on arrival

  • Gullies and channels running out through the rock, which are the paths fish use on a rising tide.
  • The state of tide at which a particular gully has enough water to hold a fish.

  What goes wrong here

  • Fishing standard beach terminal tackle and losing a whole rig, and often a fish, at every snag.
  • Standing where you cannot retreat as the tide rises. On rock this is the mistake that kills people rather than the one that costs a lead.

  Rock marks cut off, and wet kelp-covered boulders are as slippery as ice. Know your escape route and the time it closes before you climb down to fish.

• Pier and jetty

  Deep water without a boat

  Deep water, structure and lights, without a boat

  • On or near the bottom
  • Deep water

  Methods: Ledgering, Float fishing

  How this mark actually fishes

  Why fish are here

  A pier gives an angler deep water without a hull, and it gives a cod exactly the kind of edge it hunts: piles that break the tide and scour holes downtide of them where food collects. Where a pier is lit, the lights concentrate small fish through the night, which concentrates what eats them. The structure is also permanent and mapped by everybody who fishes it, which makes a pier the easiest venue on which to learn where cod actually sit.

  How to fish it

  Fish tight to the structure rather than away from it — the scour hole behind a stanchion is often within a rod length of the rail. Down the side on a running ledger frequently beats a long cast. Work out which stanchions produce on which state of tide; on most piers it is a small number of them and the difference is large.

  What to look at on arrival

  • Where the tide breaks around the piles, and which side of the pier is downtide at the state you are fishing.
  • Small fish under the lights after dark.

  What goes wrong here

  • Casting straight out and ignoring the structure you are standing on, which is the feature.
  • Arriving without a drop net on a pier high enough to need one, and losing a good fish at the rail.

• Estuary

  Where the river meets the tide

  Where a river meets the tide, and colour arrives without a gale

  • On or near the bottom

  Methods: Ledgering

  How this mark actually fishes

  Why fish are here

  An estuary is permanently doing what a storm does to a beach: moving water, carrying colour and food, over ground that changes with every tide. Cod push in on the flood to feed over mud and mussel scars that are dry six hours later, and a river carrying rain gives an estuary the coloured water that a beach only gets after a blow. Estuary cod are often smaller than open-coast fish and are frequently far more reliable.

  How to fish it

  Fish the flood and the first of the ebb, over the channel edges rather than the middle. Baits that hold up in moving water — squid, crab, tough worm — beat delicate ones. Watch the size of your lead against the run of the tide; an estuary in flood carries more water than the surf on the beach outside it.

  What to look at on arrival

  • A river running coloured after rain, which is an estuary's version of a gale.
  • The channel edge, the mussel scars and the point where a creek joins the main run.

  What goes wrong here

  • Wading out onto flats that fill behind you. Estuary channels cut people off faster than any beach.
  • Treating an estuary as a small sea. The tide runs harder and the ground changes more.

  Soft mud and a filling channel are the two hazards, and they combine. An estuary flat that took twenty minutes to walk out over can be impassable in ten.

• Boat

  Your own hull, and the freedom to move

  Over ground you could not otherwise reach

  • On or near the bottom
  • Deep water

  Methods: Drift fishing, Ledgering, Jigging

  How this mark actually fishes

  Why fish are here

  A boat removes the constraint that shapes all the venues above: you no longer have to fish where the fish happens to come to you. Banks, scoured channels, reef edges and rough ground that no cast reaches become fishable, and — decisively in winter — you can move when a mark is not producing rather than sitting it out. The fish are doing the same thing they do inshore; you are simply able to go to the edge rather than waiting at one.

  How to fish it

  Fish on the drift over ground rather than at anchor, unless the tide or the mark demands otherwise. Keep the bait in contact with the bottom: cod feed low and a bait swinging in mid-water is out of the game. Let a bite develop — a cod frequently mouths a large bait before taking it — and lift into it rather than striking.

  What to look at on arrival

  • The sounder showing the ground coming up, and fish sitting just off the up-tide side of it.
  • The rate of drift. Too fast and the bait never gets down; too slow and you cover nothing.

  What goes wrong here

  • Too little lead. Losing the bottom is losing the fishing, and most anglers under-weight rather than over-weight.

• Reef and rough ground

  Broken ground, weed and the fish that live in it

  Wrecks and hard ground, where cod are reliable and tackle is not

  • On or near the bottom
  • Deep water

  Methods: Drift fishing, Jigging

  How this mark actually fishes

  Why fish are here

  A wreck concentrates everything: it interrupts current, it grows weed and shellfish, it holds small fish, and it has been doing all three for decades. Cod hold on and around it in numbers that open ground never produces, usually near the bottom and often tight to the structure on the up-tide side where the current brings food to them.

  How to fish it

  The pass is short and the timing is everything. Get down fast on the up-tide approach, fish the moment the ground rises, and be prepared to lose the rig on the far side. A pirk or a large shad worked close to the structure covers the same water a bait does with far less time spent sinking, which matters when a drift lasts ninety seconds.

  What to look at on arrival

  • The skipper's line-up. On a wreck the drift is planned rather than accidental, and being ready at the right moment is most of the skill.

  What goes wrong here

  • Fishing through the whole drift instead of the productive part of it, and donating tackle to the wreck on every pass.
  • Winding the moment you feel the fish. A cod pulled up hard off a wreck brings the trace through everything you were trying to avoid.

Why cod are within reach, and when

Each of these is a piece of biology or hydrography, what it looks like from where you are standing, and what you can try as a result.

• Cold water brings them within casting range

  What you may see

  Sea temperature falling through autumn, and the first sustained cold snap. Local reports of codling turning up at marks that produced nothing in August.

  What to try

  Start fishing the marks you wrote off in summer. The same rock ledge that gave you wrasse in July is a cod mark in November, and the change is in the water rather than in the ground.

  Where this breaks down

  Temperature is a permission rather than a cause. Cold water lets cod be there; it does not put them there, and a cold flat calm sea can be as empty as a warm one.

  Why this happens

  Cod are a cold-water gadoid, and their comfortable temperature band sits below what a British inshore summer provides. Through the warm months the fish that are within reach of a shore angler are mostly small, and the larger ones are further out and deeper where the water is cooler. As inshore water cools through autumn, that constraint relaxes: the band of water a cod will tolerate expands towards the beach, and fish that spent the summer offshore become catchable from ground a person can stand on. This is why the British cod season is not a migration story in the way the Norwegian one is — the fish do not arrive from somewhere else so much as the temperature stops excluding them from where you are.

  What experienced anglers do — why, and the sources

  Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.

  The mechanism above, and what it rests on.

• A gale is a feeding event, and the fishing follows it

  What you may see

  Two to four days of strong onshore wind, then a dropping sea with the water still brown. Weed on the tide line. The point at which the surf is fishable but the water has not yet cleared.

  What to try

  Fish it. This is the window, and it is short — clearing water usually means the cod have gone back out. Fish close in, use a bait that smells, and expect bites much nearer the rod than in settled conditions.

  Where this breaks down

  There is a limit. Water carrying so much weed that a bait cannot stay in a fishable position is unfishable however good the theory, and the same sea that makes the fishing makes the ground dangerous.

  Why this happens

  The single most reliable pattern in British cod fishing is not a season, a tide or a bait: it is the two or three days after a big onshore sea. A storm tears weed off the ground, breaks open razor shells and mussel beds, dislodges crabs from under boulders and lifts worm beds out of the sand. That material does not vanish when the wind drops — it sits suspended and rolling in coloured water along the shore, and cod move in behind the sea to eat it. The colour matters twice over: it is the visible sign that food is in the water, and it is the cover that lets a large fish feed in three feet of water in daylight without feeling exposed.

  What experienced anglers do — why, and the sources

  Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.

  The mechanism above, and what it rests on.

• Individual cod specialise, even though the species does not

  What you may see

  What is actually on the ground you are fishing. Razor shells on the tide line after a blow, a peeler crab run in spring, whitebait pushed into a harbour mouth, sandeel in the surf. And what comes out of the fish you keep.

  What to try

  Match the local prey rather than the species' reputation, and use two baits on a cocktail so you are asking two questions at once. If the cod you keep are full of crab, fish crab.

  Where this breaks down

  The sampling was August and September in the north-eastern central North Sea, which is a feeding season and not the winter inshore period most readers of this will fish. The finding transferred is the principle of individual specialisation, not the specific prey list.

  Why this happens

  Cod are famously opportunistic and that is a statement about the population. Sorting individual North Sea cod by stomach contents produced something different: six groups in which a single prey type made up three-quarters or more of what the fish had eaten by mass — sandeel, clupeids, Norway pout, flatfish, crustaceans, brittle stars. In other words, on a given piece of ground at a given time, a great many cod are eating largely one thing. Alongside that runs an ontogenetic shift: as cod get bigger the invertebrate share of the diet falls and the fish share, predominantly herring in that study, rises. A big cod is increasingly a fish-eater and a small one is increasingly not.

• In northern Norway the season is a migration, and it is the other half of the year

  What you may see

  The calendar, more than anything on the water. Late winter, and the arrival of the run being reported locally.

  What to try

  If you are planning a cod trip abroad, plan it against the local season rather than against the one you know. February in Lofoten and February in Lincolnshire are different propositions in the same fish.

  Where this breaks down

  The window is well documented and the detail is not claimed here. The source is Norway's tourism board rather than its marine research institute, so this profile states a season and nothing quantitative.

  Why this happens

  The Northeast Arctic cod stock spends five to seven years feeding in the Barents Sea and then travels over a thousand kilometres south-west to spawn along the Norwegian coast, concentrating around Lofoten. The run happens between January and April. That is not a variation on the British season; it is its opposite. The fish are large because they are mature spawners rather than the mixed year-classes a British beach produces, they are concentrated because they are going to one place for one purpose, and they are within reach of small boats because the coast shelves steeply into deep water. A British angler's mental model — cod as an autumn fish that gets scarcer after Christmas — is exactly wrong there.

  Stated by a fisheries authority, scientific institute or recognised angling body. Authoritative, but summarising rather than demonstrating.

• They hunt edges, not open ground

  What you may see

  The beach at low water on a big spring tide, which is the only time most of it is visible. Weed lines, colour changes in the water, standing waves over a bank, the way surf breaks differently over rough ground.

  What to try

  Walk the mark at low water before you fish it in the dark. Then cast to the feature rather than to a distance, which usually means shorter and much more deliberately.

  Why this happens

  A cod feeding inshore is working a boundary. The edge of a weed bed, the scour hole downtide of a pier stanchion, the gutter between two banks, the line where rough ground meets clean sand, the foot of a boulder field. Two things make an edge worth a fish's time: food collects there because moving water drops what it is carrying when it slows, and an ambush is possible there because the fish can be close to prey without being in the open. This is why a mark that looks featureless from the promenade can be extremely specific once you know where the gutters run, and why local knowledge is worth more in cod fishing than in almost anything else.

  Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.

  The mechanism above, and what it rests on.

• Offshore, a wreck is a permanent version of the same edge

  What you may see

  The sounder, and the skipper. On a drift, the moment the ground comes up and then falls away again is the fishable part of the pass.

  What to try

  Fish the up-tide side and be ready on the drop. Most wreck cod are hooked in the first part of the drift and lost in the tackle in the last part of it.

  Why this happens

  The mechanism that puts a cod in a beach gutter puts one on a wreck: structure interrupts current, current concentrates food, and a predator that can hold station near the structure eats without chasing. What differs offshore is permanence and depth. A gutter is remade by every storm; a wreck has been in the same place for eighty years, has grown its own ecosystem, and holds fish reliably enough that skippers name individual pieces of it. Depth changes the fishing rather than the reason for it — a bait or a lure has to be got down and kept in a narrow band near the structure while the boat drifts over it, and the whole technique is about that control.

Finding them

What to look for, what it means, and how much it is worth. None of these guarantees a fish — the third column says how far each one is worth trusting.

How to fish for them

• Beachcasting a big bait into the gutter

  When: The default British winter shore method: coloured water, a dropping sea, October to February, from a surf beach or a mixed shingle strand.

  Why it works, how to do it, and what it will not do

  Why it works

  Cod feeding after a blow are working a defined trough close in, taking food that is rolling rather than swimming. A large static bait sitting in that trough is exactly what they are looking for, and holds its position long enough for a fish working along the gutter to find it by scent.

  How to fish it

  Cast to the feature, not for distance — usually forty to eighty yards. Use a grip lead so the bait stays in the trough rather than being swept out of it. One large bait on a pulley or a flapper rig, cast, and then leave it: cod bites develop slowly and reeling in every four minutes to check the bait is the commonest way to miss them.

  Tackle

  A 12-to-13-foot beachcaster rated to throw 4 to 6 oz plus bait, a fixed-spool or multiplier holding 250 yards of 15 lb line, a shock leader of 60 lb, and 5 or 6 oz grip leads. Hooks 3/0 to 6/0, because the bait is the size of the hook rather than the other way round.

  What it will not do

  • Useless in a clear flat calm, when the conditions the method depends on are simply absent.
  • Unfishable when the sea carries so much weed that a lead will not stay put.
  • Rewards local knowledge of gutters more than it rewards technique, which makes a new beach genuinely hard.
  What experienced anglers do — why, and the sources

  Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.

  What this account of the method rests on.

• Ledgering down the side of structure

  When: From a pier, a harbour wall, a breakwater or a rock ledge with deep water at the foot of it. Any time of the cod season, and particularly at night.

  Why it works, how to do it, and what it will not do

  Why it works

  The scour hole behind a pile and the gully at the foot of a wall are features within a rod length. Casting past them is casting past the fish. A running ledger down the side puts a bait in the feature and lets a cod take line without feeling the rod.

  How to fish it

  A running ledger so the fish can move with the bait, lowered rather than cast, into the scour behind the structure. Fish the state of tide at which that particular feature has flow across it. Let a slack bite develop, then wind down and lift.

  Tackle

  A 10-to-12-foot rod with a soft enough tip to show a dropping-back bite, 20 lb line straight through, a running boom and 3 to 5 oz. Heavier than a beach set-up because the fish is coming up a wall rather than across sand, and a drop net if the wall is high.

  What it will not do

  • Only works where structure and depth coincide, which rules out most of a low-water beach.
  • Crowded venues make fishing tight to structure socially difficult before it is technically difficult.

  What this account of the method rests on.

• Drifting bait over ground from a boat

  When: Boat fishing over banks, reef edges and rough ground, through the cod season and beyond it in deeper water.

  Why it works, how to do it, and what it will not do

  Why it works

  Drifting covers ground that anchoring cannot, and it presents a bait moving at the same speed as the water the food is in. On broken ground it also lets you find where on the mark the fish actually are rather than committing to one spot.

  How to fish it

  Enough lead to stay in contact as the drift runs. Feel for the ground rising, keep the bait just off the bottom rather than buried in it, and lift into weight rather than striking at a rattle. Reset the drift rather than fishing on through unproductive water.

  Tackle

  A 20-to-30 lb class boat rod, a multiplier holding 300 yards of 30 lb braid, and 6 to 16 oz depending on tide and depth. Braid rather than mono because feeling the ground through 40 metres of water is the whole method, and mono stretch removes exactly that.

  What it will not do

  • Needs a skipper or your own boat, which puts it out of reach for most readers most of the time.
  • A fast drift over deep water can make it impossible to get a bait down at all.

  What this account of the method rests on.

• Pirking and jigging over wrecks and hard ground

  When: Over wrecks and deep hard ground, particularly where the drift is short and repeated, and the standard approach on Norwegian and Icelandic deep-water cod grounds.

  Why it works, how to do it, and what it will not do

  Why it works

  A short drift over a wreck gives very little fishing time, and a heavy metal gets down and starts working immediately where a bait is still sinking. It also exploits a cod's willingness to attack a large moving object near the bottom, which is a reflex rather than a feeding decision and does not require the fish to be hungry.

  How to fish it

  Drop to the bottom, wind up two or three turns, and work the lure in long lifts and controlled drops rather than short jerks — the take is almost always on the drop. Stay in contact on the way down; a slack line during the fall is how takes are missed.

  Tackle

  A stiff jigging rod, a multiplier or a strong spinning reel with 30 to 50 lb braid, and pirks from 150 g inshore to 500 g or more in Norwegian depths and tides. The weight is set by depth and drift speed, not by the size of fish expected.

  What it will not do

  • Extremely hard on tackle over a wreck, and a snagged pirk is an expensive snag.
  • Selective for active fish. On a slow day a bait will out-fish a pirk consistently.
  • The heavy Norwegian version is genuinely tiring, and the tackle that suits it is absurd on British inshore ground.

  What this account of the method rests on.

• Working large soft plastics over structure

  When: Boat fishing over wrecks and reefs, and increasingly from deep-water rock marks and kayaks in the west.

  Why it works, how to do it, and what it will not do

  Why it works

  A large shad on a heavy jig head does what a pirk does with a more convincing profile and a better hook-up rate, and it can be fished slower — which matters when cod are near the bottom and not chasing. It suits the ontogenetic point directly: it is a fish-shaped lure for a size of cod that is increasingly eating fish.

  How to fish it

  Down to the bottom, then a slow lift-and-drop close to the structure. Keep it low. A shad worked at mid-water over a wreck catches pollack and misses cod, which is a useful accidental diagnostic.

  Tackle

  A 20 lb class boat rod or a heavy lure rod, braid, and jig heads from 60 to 200 g with 5-to-8-inch shads. Head weight is chosen to reach and hold the bottom in the tide running, and is the decision that makes or breaks the method.

  What it will not do

  • Loses to bait when fish are inactive.
  • Snags cost more than a lead does, so the economics push people back to bait over the roughest ground.

  Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.

  What this account of the method rests on.

Lures

Chosen by weight, sink rate, depth and retrieve, because those are what decide whether a lure is in front of a fish. There is no best one, and no best colour.

• Pirks and heavy metals

  A long, heavy chrome or painted metal bar with a treble or single at the tail, fished vertically rather than cast.

  Weight

  150 g to 500 g and beyond, chosen by depth and drift rather than by fish size

  Depth it fishes

  On or within a few metres of the bottom. A pirk fished in mid-water over a wreck is fishing for pollack.

  Sink rate

  Fast and near-vertical, which is the point: a pirk is fishing while a bait is still on its way down.

  Retrieve

  Long lifts and controlled drops, staying in contact on the fall. The take is on the drop far more often than on the lift, and a slack line during the fall is a missed fish.

  When it works, and when it does not

  Short repeated drifts over wrecks and hard ground, and deep Norwegian and Icelandic marks where the tide and the depth make anything lighter unfishable. It works best on active fish holding tight to structure, where speed of deployment matters more than subtlety, and it is the standard tool of the northern deep-water cod fishery for exactly that reason.

  Limitation: Snags catastrophically, is tiring to fish all day, and is comfortably out-fished by bait when the fish are not actively feeding.

  What this lure guidance rests on.

• Large soft-plastic shads on jig heads

  A five-to-eight-inch paddle-tail or curl-tail shad on an exposed-hook jig head, in white, black or natural fish patterns.

  Weight

  60 g to 200 g of head, set by depth and tide

  Depth it fishes

  Bottom and the first few metres above it.

  Sink rate

  Controlled by head weight, which is the only variable that matters — too light and it never reaches the fish, too heavy and it is in the wreck.

  Retrieve

  Slow lift and drop close to the ground, or a very slow steady retrieve just off it. Much slower than the same lure would be worked for pollack.

  When it works, and when it does not

  Over wrecks and reef where a fish-shaped profile beats a metal bar, and on days when fish are present but not committing to a pirk. It also suits the biology: larger cod eat proportionally more fish, so a large fish-shaped lure is selecting upwards through the size range rather than merely being visible.

  Limitation: More expensive to lose than a lead, which changes how boldly people fish the roughest ground.

• Muppets and lure booms above a lead

  A rubber squid skirt or a small set of lures on short snoods above a lead or a pirk, fished together with or instead of bait.

  Weight

  Whatever the lead below it needs to be

  Depth it fishes

  The bottom few metres, above whatever is anchoring the rig.

  Retrieve

  Worked with the rod rather than the reel, in the same lift-and-drop as a pirk.

  When it works, and when it does not

  As an addition to a pirk or a bait rig over deep ground, particularly in the northern fisheries where multi-lure rigs are the norm. The rubber squid skirt above a pirk is one of the oldest additions in deep-water cod fishing and is still in every Norwegian tackle shop for a reason.

  Limitation: Adds snag points to a rig already being fished over the worst possible ground, and multiplies what is lost in one break.

Baits

• Lugworm

  Why it works, and how to present it

  The staple British winter cod bait, and one of the few things a storm reliably lifts out of a beach and into the water where cod are feeding. It leaks scent continuously in coloured water, which is exactly the condition it is fished in — a cod hunting in brown water after a gale is working largely by smell, and a worm bait is a scent source that stays where it is put.

  Presentation: Big. Several worms threaded up the trace to make a bait the length of a hand, rather than one worm on a hook. Whipped with bait elastic if the cast is long or the sea is rough, because a bait that comes off in flight is a bait that fished for nobody. Frequently used as the scent half of a cocktail with squid providing the durability.

  Limitation: Soft, expensive if bought, and stripped quickly by crabs and small fish. In a warm autumn sea it can be gone before a cod finds it.

• Squid

  Why it works, and how to present it

  Durable where worm is not, visible in coloured water, and a fish-shaped item for a fish that eats increasing amounts of fish as it grows. Squid stays on the hook through a long cast and a long wait, which makes it the structural half of most winter cod baits.

  Presentation: Cut into strips or used whole as a small calamari, most often tied alongside worm as a cocktail: the worm supplies scent, the squid supplies durability and profile. Hook through the tough end so it holds; leave a tail free to move in the tide.

  Limitation: Less scent than worm or crab, so on its own it can be slow in very coloured water where smell is doing the work.

• Peeler crab

  Why it works, and how to present it

  Crustaceans are one of the six specialist prey groups found in North Sea cod stomachs and are the group small and medium cod eat most of. A crab that has just moulted is defenceless and is taken by almost everything, and a storm that turns over a boulder field delivers exactly that. When the local fish are on crab, nothing else is close.

  Presentation: Peeled, the legs removed and threaded on separately, the body whipped to the hook with elastic — an unelasticated crab bait does not survive the cast. Sized to the fish: a whole large peeler for cod rather than the small section used for smaller species.

  Limitation: Seasonal, expensive and often unobtainable in midwinter, which is precisely the cod season. The peeler run is spring and late summer, so this is more often an autumn cod bait than a January one.

• Razor fish and other shellfish

  Why it works, and how to present it

  A gale breaks razor shells out of the sand in numbers, and a beach littered with them after a blow is direct evidence of what the sea has been feeding to the fish. Using what the storm delivered is the closest a shore angler gets to matching the hatch.

  Presentation: Whole out of the shell, whipped with elastic, often on its own so the profile is not confused. Fresh matters more than with most baits — a razor that has been in the sun is a poor bait.

  Limitation: Availability is entirely weather-dependent, and collecting shellfish is regulated in many places. It is the most local of the cod baits and cannot be planned around.

• Mackerel and other fish baits

  Why it works, and how to present it

  Larger cod shift towards fish prey as they grow, and a large fish bait is a filter as much as an attractant: it discourages the small whiting and dabs that will otherwise strip a worm bait, and presents something a large cod is actively hunting.

  Presentation: A whole small fillet or a large flapper rather than a chunk, mounted so it moves in the tide. A tough fish bait can be left out far longer than worm, which suits the leave-it-alone discipline cod fishing needs.

  Limitation: Very slow when the fish present are small, and easily out-fished by worm in coloured inshore water where scent rather than profile is doing the work.

Conditions

What each of these changes, why that matters to the fish, and what it is worth trying. None of it is a rule — fishing does not have any.

Tackle

Each of these says why it is the size it is. Where a heavier outfit is suggested it is almost always about casting range or holding bottom, not about the strength needed to land the fish.

Things that actually help

What they are feeding on

What the evidence says they eat, and — separately — what that does or does not imply for what you tie on. Some of the most important prey has no angling consequence at all.

When, and where

Not one season. These are different coasts with genuinely different windows, and the boundaries move between years — they follow water temperature rather than the calendar.

Why people blank

How it is caught

• Drift fishingWorking ground rather than anchoring over it, which finds fish spread across mixed bottom instead of concentrated on one feature.
• JiggingPirks and heavy jigs worked vertically over wreck and rough ground from a boat, taking fish that are feeding above the bottom.
• Kayak fishingInshore rough ground holding cod is reachable by kayak in settled conditions, and a drifting kayak presents a bait or lure over it more slowly than a powered drift.
• LedgeringBait presented hard on the bottom from boat or shore, which is where cod feed and where the food a rough sea dislodges ends up.
• SurfcastingThe shore cod fishery: large baits fished on the bottom over rough ground in cold, coloured, disturbed water.

Gear for this fish

• Fish strip and cut baitThe workhorse cod bait, alone or tipping a worm — a tapered mackerel strip fished from the thick end so it works in the tide.
• LugwormSoft, full of body fluid, and strongly scented — which is what winter cod in coloured water are actually responding to.
• Metal jigsThe pirk is the oldest artificial in this fishery and works on the drop: a cod holding over hard ground responds to something falling and fluttering above it, which is how a wounded fish behaves and how a lifted-and-dropped metal behaves.
• Paternoster rigThe same arrangement scaled up, with fewer and stronger hooklengths, is the standard shore and boat presentation for cod over mixed ground.
• Peeler crabWidely used for cod over mixed and rough ground, frequently in combination with worm rather than alone.
• Soft plasticsA large shad on a heavy head has largely replaced the pirk over wreck and reef because it can be fished slowly at depth without the foul-hooking that an unweighted treble-hung metal produces in a shoal.
• Squid and cuttlefishA standard cod bait, alone or tipping a worm — the combination exists because worm brings the scent and squid stops it washing off.
• Uptide rigInshore winter cod over shallow rough and mixed ground are a traditional uptide target from anchored boats.

When to fish for atlantic cod

Where the places here state a season for atlantic cod, it clusters in Nov–Feb. This is a count of how many documented places name each month — evidence about when people fish for it, not a prediction of what any particular day will produce.

167 of the 197 places that record catches of atlantic cod state which months. The other 30 name no season, so they are counted in neither direction: the shape above is what the dated records say, not the whole picture. The dated records span 35 separate areas.
