Offshore renewables must not be pursued at the cost of Ireland’s biodiversity, an Oireachtas committee has been told.

According to The Irish Times, members of the Oireachtas Committee on Climate Change heard statements from various environmental and conservation groups who explained how Ireland’s waters and coastal areas are under threat from the effects of climate change as well as pollution and invasive species.

Ellen MacMahon of the Sustainable Water Network noted the important role of wind energy in decarbonising the Irish economy.

But she added that “marine protected areas are often overlooked in the role they can play in addressing the twin climate and biodiversity emergencies”.

Her comments were echoed by Dr Simon Berrow of the Irish Whale and Dolphin Group, who said offshore wind farms “cannot be considered in isolation” from their immediate environments and urged that such green energy projects are “not at further cost to Ireland’s already depleted marine habitats and species”.

West Cork is enjoying a veritable bounty of whale sightings “in dolphin numbers”, as the Southern Star reports.

Video recorded last week near Union Hall shows two humpbacks who followed a whale watching vessel “in a very sociable mood”, according to Cork Whale Watch’s Colin Barnes.

He descried it as the best marine wildlife sighting of its kind in the last two decades — a sentiment echoed by the Irish Whale and Dolphin Group’s Padraig Whooley.

Noting a recent report of as many as 100 minke whales spotted on a single boat trip, Whooley said the whale activity off the South Coast at present is “exceptional on a global scale”.

The Irish Independent covers the excitement among the denizens of Drogheda after a dolphin swimming up the River Boyne paid an unexpected visit to the town.

Reports of a dog in the water yesterday morning (Thursday 22 April) turned out to be wide of the mark when Boyne Fishermen Rescue and Recovery encountered the “medium-sized dolphin” in the River Boyne at the Upper Mell slipway, just east of the town centre and some 7km from the open sea.

The Irish Whale and Dolphin Group says the marine wildlife is likely to be a bottlenose and called for the public to contact it with any images or reports of further sighings.

While there is no immediate cause for concern, dolphins are saltwater animals and can develop serious kidney and skin problems with prolonged exposure to freshwater environments.

The Irish Whale and Dolphin Group (IWDG) has said it is “irresponsible to raise peoples' hopes” that a dolphin spotted off West Cork in recent days might be Dingle’s missing resident bottlenose, Fungie.

Cork Beo reported on Sunday (11 April) on video recorded off the Old Head of Kinsale of a playful solitary dolphin which has sparked optimism that Fungie has reappeared some six months since he vanished from Dingle Harbour, his home since 1983.

But the IWDG has moved to play down such hopes, reminding that bottlenose dolphins like Fungie “are abundant and widespread throughout Irish coastal waters”.

It added: “While the IWDG are surprised at this individual’s behaviour around the boat it was recently filmed from, it is way too early to speculate that this dolphin is Fungie.

“The IWDG have validated 13 sightings of bottlenose dolphins off the Irish coast already this month (April) from Co Kerry to Co Louth.”

The group is awaiting clearer images of the dolphin’s tail fluke or dorsal fin before it makes any confirmed identification.

“The IWDG feel it is irresponsible to raise peoples’ hopes that this might indeed be Fungie, while current evidence merely shows it to be a bottlenose dolphin behaving in an unexpected fashion,” it said.

It’s not the first video of a frolicking dolphin to cause a stir in recent weeks, as footage captured in Galway Bay last month raised hopes that Fungie had relocated along the West Coast.

Viewers in Ireland have another chance to catch a fascinating documentary on a unique expedition to the Arctic Circle tracing the origins of Ireland’s annual humpback whale visitors.

Broadcast yesterday evening on RTÉ One, Ireland to Iceland - On the Trail of the Humpback Whale follows marine wildlife researchers and volunteers with the Irish Whale and Dolphin Group (IWDG) on their weeks-long passage to Ireland in search of humpback whales in 2018.

As previously reported on Afloat.ie, Tony Whelan’s film also charts the links that the Irish crew made with Iceland and the costal communities they met along the way.

Now the film is available to watch for 30 days for viewers in the Republic of Ireland on the RTÉ Player.

The Irish Whale and Dolphin Group (IWDG) has warned the public to stay away from the final resting place of a humpback whale carcass that washed ashore in West Cork last month.

And according to the Southern Star, poor weather forecast for later this week has dampened hopes to potentially retrieve the marine wildlife remains for public display.

The carcass of the juvenile humpback whale is only the ninth recorded stranding of the species in Ireland, as previously reported on Afloat.ie.

First spotted in the waters of Roaringwater Bay, it eventually came to rest on the rocky shore at the foot of steep bank at Colla West near Schull, where IWDG volunteers have examined the remains over the weeks since.

Plans had been mooted to preserve the skeleton as a potential tourism draw for the area, the IWDG’s Pádraig Whooley said, though this would be “at great expense”.

“Although the plan was tentative, if successful, it would be a wonderful opportunity because the only other humpback whale on display is in the Natural History Museum, and that dates back to 1893,” he added.

The Irish Whale and Dolphin Group (IWDG) won the tender to provide a marine mammal observer on three fisheries acoustic surveys with the Marine Institute this year.

These include a survey for blue whiting this month, the Western European Shelf Pelagic Acoustic (WESPAS) survey during June and July and the Celtic Sea Herring Acoustic Survey in October.

The aforementioned missions are annual stock assessment surveys and cover a huge area of the Irish EEZ.

Data on higher trophic predators such as marine mammals and seabirds are essential to provide the data to support the development of an ecosystem approach to fisheries management.

Experienced offshore surveyor Dr Justin Judge will be joining each cruise to record all sightings of whales and dolphins and other interesting endangered, threatened and protected (ETP) species, as well as recording the vessels’ track and environmental conditions.

He follows in the footsteps of Dave Wall, who used data collected from these annual surveys in 2014 to built the dataset to publish the first Offshore Atlas of Marine Mammal Distribution.

Whale and dolphin strandings in Ireland for the first two months of 2021 have reached their highest peak yet with 93 records, as the Irish Whale and Dolphin Group (IWDG) reports.

The bulk of these marine wildlife findings were common dolphins, with 64 in total discovered around the Irish coast since the beginning of the year.

“Although historically the IWDG have identified January to March as a peak stranding period for common dolphins, 2021 figures are already proving to be quite high compared to the same period in previous years,” says IWDG sightings officer Stephanie Levesque.

“This time last year, IWDG had received 70 records in total, of which 40 were common dolphins.”

The total figure comprises eight species: common, bottlenose, striped and Risso’s dolphins, harbour porpoise, long-finned pilot whale, minke whale and one rare record of a humpback whale, as previously reported on Afloat.ie.

Levesque adds: “There are most likely several factors affecting this increase in reported strandings, and although we are not sure exactly what is causing it, a number of factors must be taken into account.

“As the entire country found itself in lockdown, and was spending significantly more time walking the local shores during the peak stranding period, there was bound to be more reporting taking place.”

In addition, Levesque reports that the IWDG has had a high social media reach in recent months “and perhaps more people are inclined to report these strandings”.

There is also “increasing evidence of a broad-scale movement of common dolphins from deep offshore waters into shelf edge waters” within the North-East Atlantic.

“IWDG sightings officer Pádraig Whooley has noted more common dolphin sightings reported off the coast of Ireland this winter, and where you have more dolphins, it likely leads to more strandings,” Levesque adds.

Nearly one in 10 (9%) of recorded strandings between 1 January and 28 February have “gross signs of bycatch in rising gear” such as broken jaws, cut-off tails and dorsal fin tips, and being entangled in fishing gear.

“This is likely to be a minimum as diagnosing bycatch can be quite difficult if the lesions are more subtle, or drowning has taken place with no external lesions,” Levesque says.

The Irish Whale and Dolphin Group (IWDG) says it welcomes the new public consultation on expanding Ireland’s Marine Protected Areas.

As previously reported on Afloat.ie, the Government is aiming to have 30% of Ireland’s maritime area designated as Marine Protected Areas (MPAs) by 2030.

Current coverage is just 2.13%, the IWDG says, adding that there is at present no definition of an MPA in Irish law.

“We wish to see Ireland achieve their international commitments and legal obligations, and create a truly ecologically coherent network of well-managed and well resourced MPAs, that is representative and connected,” says Sibéal Regan, the IWDG’s Education and Outreach Officer.

“In that case, it must be defined and underpinned by the appropriate legislation.”

It’s also hoped that expanding Ireland’s designated conservation areas for marine wildlife will protect core habitats from encroachment by human activity such as fishing.

Research commissioned by the IWDG has identified a number of hotspots for dolphins, porpoise and whales within Ireland’s 12-nautical-mile limit.

These have informed the group’s recommendations for potential MPA sites around the coast, available on the IWDG website here.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
