Sean Canney, Minister of State with responsibility for the inland fisheries resource, visited the River Erriff in Co Mayo recently to understand more about the current issues facing Ireland’s salmon.

Inland Fisheries Ireland (IFI) has designated the River Erriff, one of Ireland's premier salmon and sea trout fisheries, as the National Salmonid Index Catchment.

Salmon and sea trout migrating upstream in the Erriff must pass through fish counting and trapping facilities located at Aasleagh Falls, where the Erriff flows into Killary Harbour.

Since 1985, salmon and sea trout smolts and kelts migrating downstream pass through a trap located below Tawnyard Lough.

The facilities at this research station are used for a wide range of scientific research and monitoring activities on the salmonid populations and their migratory behaviour.

Minister Canney met with Dr Ciaran Byrne, CEO of Inland Fisheries Ireland, who outlined that fisheries managers and scientists have been concerned for a number of years about the declining numbers of salmon returning to the Irish coast — a key concern in this International Year of the Salmon.

In the mid-1970s, almost 1.7 million salmon were estimated to have returned to Ireland, compared to only some 250,000 today.

Salmon are a key indicator species and they tell us so much about the health of our aquatic environment, IFI says.

And the issue is not unique to Ireland, as populations over the entire southern part of the North East Atlantic — which includes France, Spain, England, Scotland and southern Iceland — have declined significantly in the past number of decades.

Following the visit, Minister Canney commented: “Salmon are an iconic fish species in Ireland. They have always had a special place in Irish culture, heritage and mythology with stories such as the ‘Salmon of Knowledge’ familiar to generations of our school children.

“While they are widely distributed throughout Irish river systems, with over 140 designated salmon rivers, the numbers of salmon returning to Irish rivers, in common with salmon rivers internationally, have shown a worrying decline in recent decades.

“Today they remain an important resource to many people, playing an invaluable ecological, social and cultural role in Ireland and across the Northern Hemisphere.

“International Year of the Salmon offers us an opportunity to start an important conversation around how we can protect, conserve and restore salmon populations in Irish and international waters and how we can inspire action.

“I am delighted to see the excellent research facility here in the Erriff. I am assured that the ongoing scientific research by IFI adds to our understanding of the issues facing salmon and will inform Ireland’s position as part of the EU delegation in discussions which will shortly take place at Nasco — the North Atlantic Salmon Conservation Organisation — on this important topic.”

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
