Emergency Containment Measures For Crayfish Plague On River Suir

#MarineWildlife - In response to a recent outbreak of crayfish plague in the River Suir and River Deel, emergency disease containment measures are needed to help prevent its spread.

Crayfish plague is a disease that kills Ireland’s native white-clawed crayfish. All crayfish that become infected will die.

The disease is easily transmitted in water or via contaminated equipment (for example on canoes, waders or nets).

Ireland holds the largest population of the white-clawed crayfish that remains in Europe.

To help protect our native crayfish from this disease, all water users are asked to operate a temporary ban on moving watersports and angling equipment out of the River Suir and River Deel catchments, commencing immediately.

Watersports and angling equipment currently in use in the Suir and Deel catchments may continue to be used there, but boats or equipment should not be transferred out of the catchment.

Limit your activity to the river section where you normally operate, avoid moving around the catchment and follow biosecurity protocols: Inspect, Remove, Clean, Dispose, Notify.

The Inland Fisheries Ireland website has more information for anglers, boaters, paddle sports enthusiasts and SCUBA divers.

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.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.

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!
