Campaigners against salmon farms have raised concerns over the state of Irish wrasse stocks after it was confirmed the fish have been taken en masse to help clean lice from farmed salmon.

As Donegal News reports, a number of salmon farms in Donegal, Galway and other areas owned by Mowi — the former Marine Harvest — have between them moved in tonnes of wild wrasse, a known ‘cleaner fish’ that feeds on sea lice, over the past four years.

Responding to a Dáil debate question from Catherine Connolly TD this past summer, Marine Minister Michael Creed confirmed that “several special of cleaner fish are used in Ireland as a method of controlling sea lice”.

But there are fears that the mass withdrawal of wrasse and other such species from the wild could tip the balance of Ireland’s delicate marine ecosystem.

“The absence of wild wrasse in bays may result in stress and disease in other large species of fish which rely on wrasse to keep them clean of parasites,” said Billy Smyth, chair of Galway Bay Against Salmon Cages.

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!
