#marinewildlife – The recent discovery by a local angler of the decaying remains of an exotic fish specimen in the River Suck at Correen Ford in the Midlands has raised further concern of the threat to our native wildlife from aquarium releases by otherwise well-meaning individuals. This latest discovery followed by that of a Yellow-bellied Slider turtle on the River Maigue, in Co. Limerick last week.

Despite the partially decomposed state of the fish, Inland Fisheries Ireland (IFI) staff, in consultation with international experts, believe the six inch-long, sharp-toothed specimen to be a Dragonfish (also known as a Violet or Dragon Goby). This fish is native to North and South America and can be purchased in Ireland for private aquariums.

As it is regarded as a warm water species, the Dragonfish is not considered to be able to survive in the wild in Ireland. However, according to Dr Joe Caffrey, Senior Research Officer with IFI, "There are many exotic species of potential concern sold in the aquarium trade in Ireland. These include non-native freshwater fishes, crayfish and aquatic plants. If these are released to the wild they could seriously threaten our native biodiversity and ecosystem function, and the continued conservation of internationally important native species in our rivers and lakes. It is imperative that the public and all stakeholders are aware of the potential damage that exotic animals or plants which are deliberately introduced to the wild can inflict upon our unique wildlife and habitats."

In recent years, human-mediated introductions of non-native species such as Asian Clam, Australian Swamp Stonecrop, South African Pondweed and Zebra Mussel into Irish waterways have resulted in detrimental impacts to native species and habitats, degraded the amenity value of areas that become infested and required costly control measures to be implemented to mitigate these impacts.

Under the European Communities Birds and Natural Habitats Regulations 2011, the unlicensed release to the wild of any animal species, which is not ordinarily resident in Ireland or a regular visitor to the country, in a wild state is an offence.

Any sightings of exotic plants or animals found in or around our waterways can be reported to IFI through the 'IFI Invasive Species' smart phone app which is available to download from the Google Play and iTunes App stores.

The app aids users to report and identify exotic species and take geo-referenced photographs that can immediately be sent to IFI scientists for review. If the sighting is of something new or particularly worrying, this will trigger an immediate on-site survey by IFI staff. IFI want as many people as possible to use this app and help it in its ongoing battle against aquatic invasive species.

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!
