Salmon farms result in sea lice increase

Salmon farms have a negative impact on wild sea trout, a new definitive scientific paper has concluded.

The study, which reviews over 300 scientific publications on the subject, confirms evidence collated since the early 1990s in Ireland regarding the impact of sea lice on wild sea trout stocks, particularly in relation to the collapse of Connemara’s sea trout stocks.

Inland Fisheries Ireland and Galway Bay Against Salmon Cages (GBASC) have both welcomed the report entitled ‘Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review’.

They argue the conclusions of the report cast doubt over plans for a massive fish farm in Galway Bay.

The project was funded by the Norwegian Seafood Research Fund which provides investment in Norwegian seafood industry-based research and development. A team of top international scientists from Norway, Scotland and Ireland reviewed all available published studies on the effects of sea lice and have concluded that sea lice have negatively impacted wild sea trout stocks in salmon farming areas in Ireland, Scotland and Norway.

The study also examined the potential effect of sea lice on salmon and concluded that sea lice have a potential significant and detrimental effect on marine survival of Atlantic salmon with potentially between 12% and 29% fewer salmon spawning in salmon farming areas.

These conclusions concur with previously published Inland Fisheries Ireland (IFI) research on the potential impact of sea lice from marine salmon farms on salmon survival. The studies reviewed indicate that salmon farming increases the abundance of lice in marine habitats and that sea lice in intensively farmed areas have negatively impacted wild sea trout populations. The effects of sea lice on sea trout are increased marine mortality and reduced marine growth.

IFI, who welcomed the study, said it has consistently called for marine salmon farms to maintain sea lice levels close to zero prior to and during the wild sea trout and salmon smolt migration period in spring. It also raised concerns regarding the location of salmon farms in the estuaries of salmon and sea trout rivers.

The Board of Inland Fisheries Ireland in a statement said: “This new scientific review paper confirms the need for very tight regulation of sea lice levels on salmon farms and raises legitimate concerns with regard to the potential impact of new large scale salmon farms proposed along Ireland’s west coast on salmon and sea trout stocks.

“Regulators will now need to consider the results of this comprehensive review when making decisions on the sustainability and approval of future marine salmon aquaculture licences and the regulation of sea lice at existing sites so as to ensure no negative impact on salmon and sea trout stocks.”

GBASC also welcomed the report and said it ‘blows out of the water’ previous research which said that sea lice cause just 1% of mortality in wild salmon.

“In light of the results of this new study we also call on Minister Simon Coveney not to grant any licence large or small for a salmon farm in Galway Bay. This new study proves that if a licence is granted for Galway Bay, it will have disastrous consequences for the wild salmon and sea trout in the Corrib and other rivers surrounding Galway Bay,” the lobby group said.

CITY TRIBUNE

Council to consider new pedestrian ‘plaza’ for Galway City

From this week’s Galway City Tribune – Councillors will be asked next month to consider a sweeping overhaul of traffic flow in the city centre as the local authority seeks to create a more pedestrian-friendly core in the wake of Covid-19.

Currently under proposal in City Hall are major alterations to traffic flow which will allow for restricted car access to Middle Street – creating additional outdoor seating space for businesses in the area struggling to cope amid social distancing requirements.

Senior Engineer at City Hall, Uinsinn Finn, said they are currently considering three different proposals to alter traffic flow on Merchants Road, Augustine Street and Flood Street to reduce the need for car access to Middle Street, while still maintaining access for residents.

“We already pedestrianised Cross Street and we will be maintaining that, and there will be a proposal for Middle Street and Augustine Street.

“Businesses in the area are very much in favour of pedestrianisation – one business has objections but the others are supportive. Another consideration is that there are residents there with parking spaces and we are trying to encourage people to live in the city centre,” said Mr Finn.

The Latin Quarter business group submitted proposals for the temporary pedestrianisation of Middle Street and Abbeygate Street Lower but Mr Finn said the proposals the Council were considering were more in the line of creating adequate space for pedestrians while still allowing residents vehicular access.

This would involve creating a circuit for car traffic moving through Merchants Road around onto Augustine Street and exiting at Flood Street.

Residents want laneway closed following pipe bomb scare

From this week’s Galway City Tribune – Residents in part of Knocknacarra are calling for the closure of a laneway and for more Community Gardaí to be put on the beat following the discovery of a ‘viable’ pipe-bomb type device in the area last weekend.

Up to 13 homes in the Cimín Mór and Manor Court estates had to be evacuated on Friday evening last when the incendiary device was discovered by Gardaí concealed in an unlit laneway, leading to the emergency services being notified.

An Army EOD (Explosive Ordnance Disposal) unit was called to the scene and removed the device – according to local residents and councillors, the Gardaí have confirmed that the device was viable.

Gardaí have declined to comment on the detail of the case but have confirmed that the matter is being ‘actively and vigorously investigated’.

Chairman of the Cimín Mór Residents’ Association, Pat McCarthy, told the Galway City Tribune that the discovery of the viable device on the narrow laneway that links their estate to Manor Court was extremely frightening for all concerned.

“For the best part of the past 20 years, we have been seeking action to be taken on this laneway which has been used for dumping and unsociable behaviour on a repeated basis.

“But what happened last Friday evening was really the last straw for us. This could have resulted in serious injury to innocent people and what is also of concern to us is how close this was to the two schools in the area,” said Mr McCarthy.

He said that over the coming days, the residents’ association would be petitioning all residents in the three estates concerned – the other two being Manor Court and Garraí Dhónaill – for action to be taken on the laneway.

Kate Middleton wearing the necklace designed by Aisling O'Brien

From this week’s Galway City Tribune – A Galway jewellery designer is the latest to experience the ‘Kate effect’ after fans tracked down the woman who created a necklace for the Duchess of Cambridge which she has worn several times since it was gifted to her during her trip to the city last March.

Aisling O’Brien’s website crashed on Wednesday night when orders poured in for the piece from around the world. The necklace costs €109 with initials, while the earrings retail for €49.

“I’d never sold more than two things outside of Ireland before. I only had three of Kate’s necklaces in stock – and now I have orders for at least 50. I’ll have to start recruiting some elves,” laughs Aisling, who only set up her website during lockdown.

The 14-carat gold necklace and earrings set was designed by Aisling specially for Kate after examining her style – “understated, elegant, simplicity” is how the Tuam native describes it.

She was contacted about the commission by physiotherapist Thérèse Tully, who wanted to give the future queen a gift as she was using her room to change at Árus Bóthar na Trá beside Pearse Stadium when the royal couple were meeting with GAA teams.
