What each one does, and what reduces it ↓

Being listed here is not permission to fish. What that means

Access, fishing rights, seasons, licences, local bylaws and permitted methods vary and can change. Check current access, permission, local regulations, closures and restrictions before you travel or fish. FishingHQ describes what the ground is and names who holds the answer; it does not hold the answer itself.

Find the authority for a jurisdiction · What FishingHQ does and does not cover

Belfast Lough is a wide, shallow, funnel-shaped inlet running some twenty kilometres inland to a city, and the fishing along it changes completely between its two ends.

THE HEAD IS SOFT AND URBAN. Mud, sand and the outfall of a river and a port, with the water progressively less saline and less clear the further in it goes. This is flounder, eel and mullet ground, and it holds fish that tolerate silt and freshwater influence rather than fish that want a tide.

THE SOUTHERN SHORE HARDENS AS IT RUNS OUT. From Bangor eastward the coast becomes low rock and boulder between small sandy bays — Ballyholme, Groomsport — with kelp and broken ground below the tideline. Wrasse, coalfish, pollack, dogfish and codling over the rough; flatfish and bass on the clean patches between. It is fished from rock platforms that are close to a road, which is unusual on this seaboard and makes it a coast of short evening sessions.

AND IT ENDS AT A CORNER WHERE THE TIDE CHANGES CHARACTER. At Orlock and Donaghadee the coast turns south and the water stops being lough water. The stream through the Copeland Islands sound runs hard, the ground gets deeper and more broken, and the fishing takes on the character of the open Irish Sea shore rather than of an inlet. Donaghadee's pier is on that corner and fishes accordingly, holding species that do not come far up the lough.

WHAT AN ANGLER SHOULD TAKE FROM THE RECORD is that the distance from the head to the mouth is short and the difference is not. Twenty kilometres separates estuarine flounder ground from a tidal sound.

What fishing here is like

A large sheltered inlet whose character runs from silt and freshwater influence at the head to hard rock and a real tidal stream at the mouth. Swell is limited almost everywhere in it — the lough faces north-east and is shallow — so this is a coast fished in weather that closes the open shores either side of it. Access is unusually easy: much of the southern shore is a coastal path with a road behind it.

Pressure is high. This is the most populated stretch of the Northern Ireland coast and its marks are within half an hour of a city.

What you can target here

One entry per fish, grouped by how you would be fishing — because the answer is a different one from the rocks and from a boat. Each entry says how strongly the sources support it and how much evidence sits behind it. This is documented quarry, not a forecast, and none of it is a statement that you may fish any particular ground.

What these strengths mean

Established quarry: Fishing sources describe this as a normal local target here, not merely as caught.
Seasonal: Well supported, and concentrated in part of the year rather than spread through it.
Places, accounts and sources are counted separately: A fish documented once at each of six marks is still documented once at each of six marks. Breadth is reported as a place count and never raises the strength, and sources are deduplicated across places so one publisher covering a whole coast counts as one. A fishery account is a source describing the fishing; a recorded catch is a report of a specific catch. They are counted apart because they are not the same evidence.

How people fish here

4 methods are recorded on the places documented here, counted from the records themselves rather than from what is practised in the country. Each opens a full guide to the technique.

Ledgering
Recorded at 5 places here, over harbour wall, bay, pier, sea loch.
Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.
Documented on the same ground: Ballan wrasse, Conger eel, European flounder, Pollack, Pouting, Saithe.
Float fishing
Recorded at 4 places here, over harbour wall, headland, pier.
Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.
Documented on the same ground: Ballan wrasse, Conger eel, European flounder, Pollack, Pouting, Saithe.
Kayak fishing
Recorded at 3 places here, over bay, harbour wall, sea loch.
A platform rather than a technique: quiet, shallow-draught access to water no other craft reaches, bought at the price of exposure, and a discipline where the decision not to launch is part of the skill.
Documented on the same ground: Conger eel, European flounder, Pollack, Pouting, Saithe, Atlantic cod.
Spinning
Recorded at 2 places here, over headland, pier.
Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.
Documented on the same ground: Ballan wrasse, Conger eel, Pollack, Saithe, Atlantic mackerel.

These are the methods documented at the places FishingHQ holds here. A species listed beside a method is documented on the same ground, which is not the same as being taken that way — where a source establishes the method a fish was caught on, it is stated on that place’s own page.

What dominates

Shore fishing from low rock and small piers for wrasse, coalfish, pollack, codling and dogfish. Flatfish and mullet fishing in the softer water at the head of the lough. Bass lure fishing along the rock and bay shore, which has grown here as it has everywhere on this coast. Small-boat fishing out of Bangor and Donaghadee over the broken ground and around the Copeland Islands.

The water available

A shallow funnel-shaped sea lough with intertidal mud and sand at its head, giving way eastward to low basalt and greywacke rock, boulder ground and kelp between small sandy bays. A working port and a marina at the head, small harbours along the south shore. At the mouth, deeper broken ground, an island group and a sound with a hard tidal stream through it.

How the rules are structured

Northern Ireland administers its own sea fisheries measures, which are not the same as those in English, Welsh or Scottish waters and are not the same as those in the Republic a short distance south. Harbour structures are operational infrastructure whose access is the harbour authority's to grant. Parts of this shore and the islands off it carry conservation designation affecting access and collection independently of any fisheries measure. FishingHQ does not state what any current rule is: measures, designations and local byelaws change, and the answer differs by species and by stretch of coast.

Who to ask

The Northern Ireland department responsible for agriculture, environment and rural affairs, which administers sea fisheries measures and marine conservation here.
The Northern Ireland Environment Agency and the site management bodies, where a coastal or marine designation affects access or activity.
The harbour authority at each port, for access to and fishing from harbour structures. Several of these are working fishing ports rather than public quays.
The landowner, where access to the shore crosses land in private or National Trust ownership.

Words you will meet

The lough: Used locally without qualification for Belfast Lough. On the far side of the Ards Peninsula the same word without qualification means Strangford, which is a different body of water with different rules of thumb.

Conditions and hazards

Belfast Lough is the most forgiving sea water in Northern Ireland and the risks here are the ordinary ones rather than the dramatic ones. Cold water applies year-round and it is the killer on this coast as on every other: cold-water shock incapacitates a strong swimmer in under a minute, and most of the marks along the south shore put a person over deep water within a step.

The rock platforms between Bangor and Groomsport are low and easy, which is exactly why they get fished in conditions that would keep people off a cliff. Weed on greywacke is slippery well above the tideline.

The corner at Orlock and Donaghadee is the exception and should be treated as a different coast: the stream through the Copeland sound runs hard, and a person in that water is going somewhere.

Who to ask before fishing any of these

FishingHQ does not know the current access position here. Sea angling access in Northern Ireland is governed by landowner permission, harbour and council byelaws, and fisheries and conservation measures, all of which change. Check the current position with the Department of Agriculture, Environment and Rural Affairs, the harbour or council, and the landowner before going. This water is tidal and transitional, so the freshwater regime may also apply above the tidal limit: FishingHQ does not know the current access position here. Angling in Northern Ireland generally requires both a rod licence from the relevant fisheries body and a separate permit for the water, and the two are issued by different bodies. Rules, seasons and permit arrangements change. Check with the Department of Agriculture, Environment and Rural Affairs, the Loughs Agency where relevant, and the permit issuer before going.

Safety

Cold water shock — Can cause serious injury or death

Irish Sea temperatures stay low well into summer and rise little at the surface even in warm weather. Cold-water shock causes an involuntary gasp and loss of breathing control within seconds of immersion, and it incapacitates strong swimmers before any question of endurance arises.

What reduces it: Treat every mark that puts you over deep water as a mark where a fall means immersion, and dress for the water rather than the air. A buoyancy aid works in the first minute, which is the minute that decides the outcome.

Slips, trips and falls — Can cause injury needing treatment

These are working fishing ports, not promenades. Quay edges are unfenced and often high above the water at low tide, vessels manoeuvre without warning, and gear, ropes and ice are moved across the quay by machinery. A person in the water inside a harbour has vertical walls on every side and nothing to climb.

What reduces it: Treat access as the harbour authority's to give and to withdraw, and expect it to be withdrawn while vessels are working. Stay off the fairway side, keep clear of moving gear, and know where the nearest ladder and lifebuoy are before starting.

Precautions that always apply here

Check the tide before you go and know your exit route. Being cut off is the commonest way a shore session becomes a rescue.
Tell somebody where you are going and when you expect to be back.
Carry a charged phone in a waterproof case, or another means of calling for help.

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

Where to go next

What swims here

European sea bassThe low rock and small sandy bays between Bangor and Donaghadee are the shape of ground bass hunt, and the corner at Orlock where the stream through the Copeland sound begins to run is the hydraulic feature this coast has to offer them.
