Cranfield and Carlingford Lough

Sea loch · Brackish water · in The Mourne coast and Carlingford Lough

A glacial fjord running fourteen kilometres inland between the Mourne and Cooley mountains, with a shallow bar across its mouth, deep water inside, extensive mussel and oyster ground, and a clean sand shore at Cranfield outside.

Safety: moving water and currents — can cause serious injury or death. One more point applies here.

What each one does, and what reduces it ↓

FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.

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
Regular local target
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.
How breadth is counted
A fish documented at six marks is shown as six marks: breadth never raises the strength on its own. A fishery account describes the fishing; a recorded catch reports one specific catch. How evidence is weighed.

Also associated with this ground

Recorded as present here without a documented method or strength behind them.

Fish documented nearby, not here

Nothing below has been documented at Cranfield and Carlingford 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.

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.

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.

  • Spinning

    Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.

  • 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.

The ground and the water

The ground
A glacial fjord running fourteen kilometres inland between the Mourne and Cooley mountains, with a shallow bar across its mouth, deep water inside, extensive mussel and oyster ground, and a clean sand shore at Cranfield outside.
Exposure
The mouth takes Irish Sea swell from the south-east; the lough inside is sheltered by mountains on both sides, which also funnel the wind along its axis.
Depth
Deep in the fjord basin, shallow over the bar at the entrance.
Tide and flow
A strong stream through the constricted mouth over a bar, with an international boundary running down the middle of the water and two jurisdictions either side of it.

Through the year

Bass and ray through the warmer months, flatfish year-round, and a substantial commercial shellfish fishery in the lough.

Safety

Moving water and currents — Can cause serious injury or death

The bar at the lough mouth breaks when an Irish Sea swell meets the ebb, and the stream through the entrance is strong. The combination has taken vessels and it is close to a shore that looks benign.

What reduces it: Treat the entrance as a bar crossing requiring current local knowledge, never attempt it on an ebb against a swell, and stay clear of the mouth channel from the shore.

Cold water shock — Can cause serious injury or death

UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.

What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.

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.

Particular to this water: Shellfish harvesting areas are classified for food safety and are opened and closed on monitoring results a gatherer cannot see. Neither cooking nor appearance removes a biotoxin. Check the current classification with the local authority before taking anything.

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.
  • The Republic of Ireland's sea fisheries authority, for the southern side of Carlingford Lough, where rules differ from those a few hundred metres north.
  • The cross-border body with responsibilities in Carlingford Lough, for matters inside the lough itself.
  • The Loughs Agency, which is the cross-border body for the Carlingford catchment.
  • The harbour authority, for navigation in the lough and its entrance.

On a narrow screen the plot is wider than the screen and scrolls sideways inside its frame. Positions are approximate by design — they are capped at about a hundred metres and describe where a named public place is, not where fish are and not a mark.
