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
Established quarry
Fishing sources describe this as a normal local target here, not merely as caught.
Recorded here
At least one credible public account of this species being caught here. That is all it means.
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.

Fish documented nearby, not here

Nothing below has been documented at Keem Bay, Achill Island 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.

How people fish it

Practised here: Sea fishing, Spearfishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

  • Spinning

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

  • Float fishing

    Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.

  • Shore diving

    Entering and leaving the water from land under your own power — the most accessible spearfishing and the one where the entry and exit are the dangerous part.

The ground and the water

The ground
A steep-sided sand bay at the western end of Achill Island, enclosed between high ground on both flanks, with clean sand in the bay itself and boulder and reef along the edges under the cliffs.
Exposure
Open to the west and to full Atlantic swell, and sheltered from almost everything else by the enclosing headlands, which makes it fishable in conditions that shut the open coast.
Tide and flow
Streams run hard past the headlands either side of the bay and comparatively little inside it, so the bay fills and empties more gently than the water a few hundred metres away.

Safety

Cliffs and rock platforms — Can cause serious injury or death

Anglers are swept from rock platforms by individual large sets rather than by the average sea, which means the conditions that kill frequently look survivable for the twenty minutes before they arrive. Wet rock, weed and a swell running onto a sloping platform remove any chance of recovery.

What reduces it: Watch the water for a full set cycle before committing to a position, know the escape route and how long it takes, wear a flotation aid rather than carry one, never fish a platform alone, and treat a rising swell forecast as a reason not to go rather than a reason to be careful.

Cold water shock — Can cause serious injury or death

Northern European 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.

Moving water and currents — Can cause serious injury or death

Narrow sounds, estuary mouths, harbour entrances and channel edges run hard on the tide, and the water moving through them is a whole bay emptying and filling through a gap. Somebody who enters that water is carried, not swum, and shingle and sandbanks shift under the current.

What reduces it: Treat the state of the tide as part of the mark rather than as a timing detail. Do not wade a channel edge. Stay off shifting banks on a making tide.

Tides and being cut off — Can cause serious injury or death

Tidal islands, causeways, strand crossings and rock gullies that are dry ground at low water flood on the tide, and the water arrives behind the angler rather than in front of them. The Irish west and south coasts carry a large number of these and several are the ordinary way onto a mark.

What reduces it: Work out the tide for the day before walking out, and work out the exit rather than the entrance. Set an alarm for the turn. Never assume a crossing that was dry on the way out will be dry on the way back.

Fishing alone — Can cause serious injury or death

Much of this coast is remote, has no mobile coverage and is a long way from help, so an ordinary injury — a turned ankle on broken rock, a fall on a wet slope — becomes a serious problem because nobody is coming and nobody knows where to look.

What reduces it: Tell somebody the mark and the return time. Carry a means of calling for help that does not assume mobile coverage. Do not fish exposed rock alone.

Rules and access

FishingHQ does not know the current access position here. Sea angling in Ireland is not generally licensed, but access rights, landowner permission, harbour and local authority rules, conservation designations and national fisheries measures all apply and all change. Check the current position with Inland Fisheries Ireland, the harbour or local authority and the landowner before going.

Who holds the answer:

  • Inland Fisheries Ireland, which administers angling and fisheries protection.
  • The harbour or local authority, for access to structures and the shore.
  • Inland Fisheries Ireland, for freshwater fisheries, for salmon and sea trout licensing and tagging, and for the sea angling conservation measures it administers.
  • The government department responsible for the marine, and the Sea-Fisheries Protection Authority, for sea fisheries measures, minimum sizes, bag limits and protected species.
  • The National Parks and Wildlife Service, where a designation constrains access, disturbance or collection.
  • The Food Safety Authority of Ireland and the shellfish classification and biotoxin monitoring programme, before anything filter-feeding is taken.
  • The harbour authority, local authority, club or landowner controlling the specific structure or shore, whose permission is theirs to give and is not stated here.
  • The Irish Coast Guard and the RNLI, for safety guidance on this coast.
