Crayfish plague has been confirmed in the River Nore in Co Kilkenny, marking the eighth record in Irish rivers since 2015 — and the third detected this year alone, as TheJournal.ie reports.

Outbreaks of crayfish plague pose a significant threat to the survival of Ireland’s native white-clawed crayfish, according to the National Parks and Wildlife Service (NPWS).

Ahead of a seminar on the response to recent outbreaks earlier this summer, the NPWS appealed to all water users to take responsible action and follow guidelines under the ‘Check-Clean-Dry’ protocols.

That followed news of crayfish plague in the River Maigue near Adare in Co Limerick, which is now predicted to lose its population white-clawed crayfish, a globally endangered aquatic species.

The NPWS also revealed that non-native crayfish have been identified in the wild in Ireland for the first time, at a location not disclosed.

Brian Nelson of the NPWS said: “The discovery of the non-native crayfish species in the wild is of concern as this has never been found before in Ireland.

“Although the species is one we would not have predicted, it presents us with a greater challenge of eradicating the species.”

The keeping and importing of mon-native crayfish is now illegal, and anyone with specimens should contact the NPWS.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
