#Angling - Inland Fisheries Ireland has published its 2017 fish stock survey for the Owenriff catchment as well as its rehabilitation plan for the system to promote the recovery of brown trout and salmon in its lakes and rivers.

The Fish Stock Survey — which was conducted in the summer of 2017 and forms the basis for the Rehabilitation Plan — deduces that the introduction of pike into the catchment has been the significant factor in the declining fish stocks.

“As there are little or no major anthropogenic pressures in the catchment to cause the decline in fish stocks, it is reasonable to infer that the introduction of pike and their subsequent range expansion in the Owenriff catchment (with impacts of competition for food and space and predation on resident and migratory fish) is the main factor causing the decline of brown trout and salmon in the Owenriff catchment. Research from Europe and North America supports this finding,” the reports states.

Anthropogenic pressures include human-induced factors such as urban growth, deleterious discharges, farming activities and introduction of alien species.

Although pike were captured for the first time by IFI staff in 2009 in two lakes in the catchment (Loughs Bofin and Agraffard) and efforts were made by IFI staff to remove the pike from the system, they did not show up in two catchment-wide surveys in 1997 and 2007 and were only officially recorded in a survey for the first time in 2015.

However, the latest report, from the 2017 survey, confirms that pike are present all over the Owenriff catchment “in areas where they can freely gain access and in some areas where they cannot naturally gain access.”

Welcoming the publication of the two reports, Minister Sean Kyne TD said: “We have acted swiftly since the interim results of this survey became known. In late January, I announced that Inland Fisheries Ireland is to commence fish stock management operations on the Owenriff catchment to protect and restore trout stocks which have been impacted by recent introductions of pike to the catchment.

“The consequences of not taking wider remedial action on the basis of these survey results would lead to further decline in ecological biodiversity in the catchment, so I very much welcome the publication by IFI of the Owenriff Fish Population Rehabilitation Plan 2018.”

The minister continued: “The purpose of the plan is to develop a fisheries rehabilitation project that can be undertaken on the catchment to promote the recovery of the brown trout (both resident and migratory Corrib) and salmon populations in both lakes and rivers. It will take time and will be costly, but we are already underway with this very constructive and positive roadmap.”

With stock management actions having already commenced, the success of the broader rehabilitation project will depend on applying the correct tools to rehabilitate the brown trout and salmon populations in the Owenriff catchment.

These include fisheries enhancement works in selected sub-catchments to favour brown trout and salmon; genetic restoration; removing the problem (pike control); reducing anthropogenic impacts in the catchment; public awareness (especially in relation to the impacts of the introductions of species not indigenous to an area); interagency co-ordination; climate change mitigation; and any other necessary measures.

The Owenriff catchment is located on the north-western end of the Lough Corrib catchment, and the main Owenriff River drains into Lough Corrib Upper downstream of Oughterard, Co Galway. The Lough Corrib catchment itself is the largest and most important wild salmonid catchment in Ireland, and Lough Corrib is considered the premier wild brown trout fishery in Ireland.

The Owenriff rehabilitation plan and 2017 fish stock survey can both be downloaded from the IFI website. Afloat.ie also has more on IFI's stock management plan for Ireland's trout waters in 2018.

#Angling - Sean Kyne, Minister of State with responsibility for the inland fisheries sector, has announced that Inland Fisheries Ireland will shortly commence fish stock management operations on the Owenriff catchment near Oughterard in Co Galway.

The measures to protect and restore trout stocks, which have been impacted by recent introductions of pike to the catchment, were promised last November upon the development by IFI of a specific stock management plan.

“The Owenriff catchment is one of the most important spawning and nursery tributaries of Lough Corrib, our most renowned wild trout fishery,” said Minister Kyne as he made the announcement today (Monday 29 January).

“Previous scientific studies have shown it contributed 15% of the wild trout found in Lough Corrib, and each year thousands of wild trout and salmon migrate upstream into the Owenriff to spawn.

“I am committed to protecting and rehabilitating the system and welcome IFI’s stock management plan which I have asked to be implemented immediately.”

IFI will be commencing a focused and intensive effort aimed at reducing the numbers of pike in the Owenriff catchment over the coming year.

While pike cannot be completely eradicated, the project will reduce numbers to a level where they are not impacting significantly on salmonid stocks.

It is expected that ongoing maintenance operations will be required in future years to help maintain the trout population.

Minister Kyne also emphasised that, in tandem with the stock management plan, IFI is also preparing an Owenriff Fish Population Rehabilitation Plan which aims to ensure trout stocks and habitats are restored and protected, thereby providing the best opportunities for a successful trout population. The plan will be available shortly.

Survey results are currently being compiled and will be available from the IFI website. Further information on the stock management plan is available HERE.

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.
