Belfast Lough
Sea loch · Brackish water · in Belfast Lough and the north Down shore
A broad, shallow, soft-bottomed sea lough with a dredged shipping channel down its middle, extensive mudflats at its head and reclaimed industrial land on both shores.
Safety: cold water shock — can cause serious injury or death.
FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.
Fishing places on Belfast Lough
One publicly documented place inside this one.
Harbour wall
The harbour arm on the north shore of Belfast Lough beneath the Norman castle, fished from the end of the arm on the castle side over ground that is clean enough to cast short of the newer breakwater. A river mouth a kilometre further along holds large mullet shoals in the warmer months.
Documented here: European flounder, Pouting, Saithe and 6 more
What you can catch here
Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

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.
Also associated with this ground
Recorded as present here without a documented method or strength behind them.
Recorded here, but not a species to target
These are recorded here and are not quarry. Each is either assessed as Critically Endangered or protected by statute in this jurisdiction, and taking one may be prohibited outright — elsewhere every rod-caught fish must be returned. Read the species page and check the current rules with the authority before fishing.
Fish documented nearby, not here
Nothing below has been documented at Belfast Lough itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.
Widely documented on this ground
Documented at three or more neighbouring places, fished a way this place is also fished. That is a pattern about the ground rather than about any one mark, and it is the closest this site comes to saying you will probably meet a fish somewhere nothing has been written about.
From the shore
- Pollack — documented at Donaghadee pier; Bangor and Ballyholme; Groomsport (+1 more)
- Ballan wrasse — documented at Donaghadee pier; Orlock Point; Bangor and Ballyholme
- Saithe — documented at Bangor and Ballyholme; Groomsport; Orlock Point
- Atlantic mackerel — documented at Donaghadee pier; Bangor and Ballyholme; Groomsport (+1 more)
Also documented at neighbouring places
One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.
From the shore
- Conger eel — documented at Donaghadee pier; Bangor and Ballyholme
- Pouting — documented at Bangor and Ballyholme
How people fish it
Practised here: Sea fishing.
Methods the sources name for this ground. Each one is explained in full on its own page.
- Ledgering
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.
- Kayak fishing
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.

Through the year
The months the sources attach to each species here. Where a species carries no season it is listed underneath rather than assumed to run through the year.
| Species | J | F | M | A | M | J | J | A | S | O | N | D |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Atlantic cod — seasonal, recorded in November, December, January, February. | ||||||||||||
| Thick-lipped grey mullet — seasonal, recorded in June, July, August, September. | ||||||||||||
| Whiting — seasonal, recorded in November, December, January, February. |
Recorded here with no season stated: European flounder.
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.
Rules and access
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.
Who holds the answer:
- The Department of Agriculture, Environment and Rural Affairs, for sea fisheries and marine conservation in Northern Ireland.
- The harbour authority or council, for access to the structure or the shore.
- The Department of Agriculture, Environment and Rural Affairs, for rod licensing and fisheries regulation.
- The Loughs Agency, in the Foyle and Carlingford catchments.
- The club, association or owner that issues the permit for the water.
- 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.
