#MARINE WILDLIFE - The Northern Ireland Environmental Agency (NIEA) has indicated the possible presence of Japanese sea squirt on the bed of Strangford Lough, as the Press Associaton reports.

Experts are attemping to confirm the identity of the invasive organism that has posed a threat to mussel and scallop populations across the Irish Sea in north Wales.

The sea creature, Didemnum vexillum, spreads like a blanket across the seabed and other surfaces, smothering shellfish and other marine life in the process. It is often transported over large distances on boat hulls and fishing equipment.

It was discovered late last year in Holyhead marina, and Welsh athorities spent £250,000 on an extermination project to prevent its spread into the Menai Strait - at the heart of the region's shellfish industry.

Dr Rohan Holt, a senior scientist from the Countryside Council for Wales, has now been called in to advise on how to manage the threat should it indeed be confirmed as the Japanese sea quirt.

Meanwhile, members of the public have been urged to report any possible sightings of Japanese sea squirt with photos through the 'Alien Watch' section of the Invasive Species Ireland website.

#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.

#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.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
