Waterways Ireland advises all users of sightings on the Royal Canal at Ashtown of a large invasive rodent species that is highly damaging to river, lake and canal banks.

As previously reported on Afloat.ie, the coypu — also known as the nutria in the United States — is regarded as a destructive invasive species and pest, posing a threat to agriculture, the stability of river banks and even coastal defences.

The coypu is an EU-regulated species of concern with trade, transport and reproduction restrictions in place (No.1143/2014).

The large river rats can also carry a number of serious diseases communicable to humans and domestic animals.

Waterways Ireland says coypu eradication programmes can cost up to several millions of euro and are not always successful.

Most recently there were sightings of the rodents in Cork city two years ago, after a number were trapped by the National Parks and Wildlife Service (NPWS) in a tributary of the River Lee.

But their presence across the country in the capital raises concerns about their further spread throughout Ireland’s inland waterways.

Waterways Ireland has provided a checklist for how to spot a coypu, which are often confused with common otters:

  • Large semi-aquatic rodent up to 1 meter in head to tail length. Features same in juveniles.
  • It can weigh 5-9kg.
  • It has webbed hind feet.
  • Dark fur often with lighter ends and has a white muzzle.
  • Has long cylindrical tail (not fur tail like otter) and small slightly protruding ears.
  • Distinctive features are large bright orange-yellow incisor (front) teeth usually visible.
  • Coypu are generally found near permanent water.

Do not attempt to engage, trap or harm these animals.

Waterways Ireland appeals for the public keep a lookout along the waterways and especially along the Royal Canal at Ashtown, and report sightings (with photos is possible) to any of the following:

#MarineWildlife - Cork residents near the River Lee are urged to be report any sightings of coypu after one of the large rodents was seen in Cork city last week.

The invasive species was released within the last two years in the Curraheen River, a tributary of the Lee, with the National Parks and Wildlife Service (NPWS) trapping 10 of the large river rats since then, according to the Irish Examiner.

But the NPWS now seeks the public’s help in identifying how far beyond the Curraheen they might have spread, with possible sightings on the Cork-Bandon road, at Monkstown on Cork Harbour and in streams north of the city.

The situation is a far cry from two years ago, when fears of a coypu invasion of Ireland’s inland waterways were dismissed upon the news of a single three-foot rodent found in a Tipperary stream, as previously reported on Afloat.ie.

Also known as nutria in the United States, the rodents are regarded as a destructive invasive species and pest, posing a threat to the stability of river banks and even coastal defences.

#MarineWildlife - Rodney is the name given to a giant river rat found swimming in a Tipperary stream last week, as TheJournal.ie reports.

The three-foot rodent is a coypu, native to South America, and is the first of his kind ever found in the wild in Ireland.

After his discovering in a river in Kilnasculy, Rodney is now in the care of the Kildare Animal Foundation Wildlife Unit, whose Dan Donoher believes the animal must have been a kept as a pet before escaping or being released by its owner.

The coypu is better known as the nutria in the United States, where it is regarded as a destructive invasive species and pest, particularly in the southern Gulf Coast region.

But Dononher told RTÉ Radio 1's John Murray Show that there's no fear of a coypu invasion in Ireland's waterways just yet.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

RV Tom Crean Specification Overview

  • Length Overall: 52.8 m
  • Beam 14m
  • Draft 5.2M 

Power

  • Main Propulsion Motor 2000 kw
  • Bow Thruster 780 kw
  • Tunnel thruster 400 kw

Other

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
