Thousands of native oysters have been planted in Belfast Lough in the latest effort to restore their presence in Northern Ireland’s waters.

Some 2,000 adult and 30,000 juvenile European oysters from Scotland have been placed on the seabed north-east of Belfast as part of a pilot project led by Ulster Wildlife, as BBC News reports.

It’s hoped that the placement will spark the formation of a natural reef where oyster spat from nurseries around Belfast Lough can thrive.

As previously reported on Afloat.ie, Ulster Wildlife is overseeing a network of oyster nurseries in Bangor Marina, Belfast Harbour, Glenarm and Carrickfergus.

Ulster Wildlife’s Dr Nick Baker-Horne said these oysters “are a missing habitat, a missing species, that do fantastic things for biodiversity but also have some really fantastic supports for our environment [such as] improving water quality, defending our coasts from big waves and also supporting juvenile fish as a fantastic habitat for those commercially important fish species”.

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!
