#NewsUpdate - The First Minister of Wales, Carwyn Jones who visited Dun Laoghaire last week for the RMS Leinster centenary, the following day paid a visit to Anglesey in north Wales to announce the Purple option as the preferred route for the third Menai Strait (Afon Menai) crossing.

According to the Welsh Government the Purple option would see a new bridge constructed to the east of the existing Britannia Bridge. Additional facilities for pedestrians and cyclists will be included as part of the scheme.

An appraisal of the options revealed the Purple option provides the highest economic benefits, offers ‘high’ value for money and is the best performing in terms of highway alignment. It was also the most popular option of the public consultation with 25 per cent of respondents selecting it as their first choice.

As part of the next stages, a procurement exercise will take place to appoint Technical Advisors to develop the preliminary design and prepare for publication of draft Orders and an Environmental Statement.

Further analysis is also required as part of the next stage of development to determine which form of bridge is most suitable. The cost of the structure is dependent on this analysis.

First Minister Carwyn Jones said: “The A55 is important locally, nationally and internationally. It provides the main economic artery for North Wales and connects the region with the rest of Wales, the UK and Europe. (Afloat adds see related story on Brexit and the A55)

“The Britannia Bridge is the only section of the route which is single carriageway and we know this reduction in lanes leads to congestion at peak times and during the tourist seasons. There is very strong case for increasing capacity across the Menai and I am delighted the Welsh Government is taking action to address the issue.

“Based on the appraisal undertaken on the options, the Purple Option performs best and would be vital in improving journey times, strengthening the A55’s resilience, and ensuring safer travel across the Menai Strait.

“It will also provide economic benefits and ensure the route is fit for purpose as traffic volume is expected to increase over the years to come.”

#OLYMPICS 2012 - The RNLI will play a "key role" during the Olympic torch relay ahead of the London games this summer, as Yachting and Boating World reports.

On 28 May the Olympic torch is set to visit Anglesey in north Wales, when it is taken along the Menai Strait on board the RNLI's Annette Mary Liddington.

The torch will again be carried by RNLI volunteers on 18 July when it is ferried to shore from a tall ship in Dover harbour aboard the all-weather lifeboat City of London II.

Dover RNLI's operations manager Roy Couzens said: “We are very much looking forward to being involved on the day – and believe me, when that torch is at sea in our lifeboat, it couldn’t be in safer hands!”

The Olympic torch relay begins in Plymouth on 19 May and finishes at the Olympic Stadium on 27 July. Its two-month-long journey will take it throughout Britain and Northern Ireland, and includes a visit to Dublin on Wednesday 6 June.

An interactive map of the complete torch relay route is available on the official London 2012 website HERE.

#MARINE WILDLIFE - Work on exterminating sea squirts at a marina in north Wales has begun.

The £250,000 (€301,000) project by the Countryside Council for Wales involves attaching giant bags to the subsurface structures around the marina in Holyhead, which is hoped will stop the clean flow of water to the sea squirts, causing them to suffocate and die.

Marine biologist Rohan Holt, who is managing the project, said: “If we successfully eradicate the sea squirt, we will work hard to make sure that it does not recolonise.

"This will mean careful monitoring in Holyhead marina and other marinas and popular mooring areas throughout Wales to check that it hasn’t reappeared."

The sea creature threatens shellfish by spreading like a blanket across the seabed and other surfaces.

As previously reported on Afloat.ie, colonies of the invasive Japanese sea squirt are posing a throat to mussel and scallop bed in the Menai Strait between Anglesey and the mainland.

Boats from Ireland have been blamed for carrying the invasive pest into Holyhead.

The Daily Post has more on the story HERE.

#MARINE WILDLIFE - Colonies of the invasive Japanese sea squirt are posing a threat to mussels and scallops in north Wales - and Irish boats are to blame, according to the Daily Post.
The sea creature - which threatens shellfish by spreading like a blanket across the seabed and other surfaces - has been discovered in Holyhead marina, allegedly carried in on the hulls of boats from Ireland.
And fears are growing that if the marine pest spreads to the Menai Strait, the effect on the local shellfish industry could be "disastrous".
To combat the problem once and for all, the Countryside Council for Wales will spend £250,000 of Welsh government funding on an extermination project at the marina, using plastic bags to smother the sea squirts and setting up quarantine facilities for incoming vessels.
The project is expected to be completed by the end of the year.

Two mussel dredger-trawlers made a rare transit of Dalkey Sound, last Friday, writes Jehan Ashmore.

The sound which is located to the south of Dublin Bay is not used by commercial traffic but is frequented by pleasure-craft, local fishing boats from Dun Laoghaire. In addition to occasional traffic by the Irish Naval Service, Marine Institute research vessel RV Celtic Voyager, the GSI's RV Keary and foreign tall-ships.

Leading the pair of mussel dredgers was the Belfast registered Mytilus (B-449) named after the mussel species 'Mytilus edulis' and the Wexford registered Branding (WD-4A).

The vessels were making a southerly direction as they headed across Dublin Bay towards Dalkey Island. Mytilus lowered a mussel cage bucket into the sound which was dragged on two separate occasions over a short distance running parallel between the island and the coast.

The operation was all too brief as the Mytilus then proceeded into Killiney Bay followed closely astern by Branding. Upon entering the neighbouring bay, both vessels conducted dredging activity before continuing south beyond Bray Head.

Mussel grounds are located throughout certain hotspots in the Irish Sea and earlier this month, it is reported that there was a notable increase in mussel dredgers in Bangor, Northern Ireland. The dredgers were the Mytilus and Branding which berthed at the Co. Down harbour after a lengthy period of relative inactivity.

Mytilus was built in The Netherlands by Scheepwerf Van Os Yerseke B.V. and appeared in an episode of the successful BBC TV series 'Coast'. At the time of the broadcast she was registered at Beaumaris, Anglesey and was seen working in the northern approaches of the Menai Straits. The fishery grounds are ideally suited for the growing processes required in farmed mussel production.

Branding was also built by a Dutch shipyard, Kooieman in 1988 and her design is typical of the mussel dredgers based in Wexford. The market for mussels is mainly from the northern European countries of Belgium, France and the Netherlands.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
