A rare sight was caught on camera this past week with the birth of a bottlenose dolphin in Glandore Harbour.

Following reports on Monday (15 April) to the Irish Whale and Dolphin Group (IWDG) of a large gathering near Mizen Head of some 25 bottlenoses — a dolphin species not frequently seen off West Cork — a second similar-sized group was spotted two days later some 60km to the east at Glandore.

Local IWDG member Heather Mahmood flew her drone over the Glandore pod to capture some footage and images, and upon reviewing the results with her daughter Ruá on Thursday evening, the pair were surprised to discover what appeared to be a dolphin giving birth.

After sending the footage and images to the IWDG, sightings officer Pádraig Whooley came to the same conclusion.

“[It appeared] that it was indeed a female either giving birth or in the process of, as the appendage [seen protruding from the dolphin] looked very similar to a tiny, floppy tail fluke,” Whooley said.

“It is known that to maximise the chance of a successful birth, which can be a long process for all mammal species, cetacean calves are born tail-first. This is an adaptation to living in an aquatic environment, as it gives the new born the maximum breathing time inside the birth canal — that first breath being the critical one.”

Whooley referred to the IWDG’s resident experts on bottlenose dolphins, Simon Berrow and Mags Daly of the Shannon Dolphin Project, who were just as astounded.

“Neither of them have ever witnessed the birth of a bottlenose dolphin, despite being involved in monitoring the resident Shannon population now for over 30 years,” Whooley said.

“In fairness, how could they have, as this behaviour could really only be detected from an aerial perspective, which we now have at our disposal.”

The IWDG shared their findings with Cromarty-based Dr Barbara J Chaney, who studies the Scottish bottlenose population that overlaps with our own, “and her thoughts mirrored ours, that this footage was unique, both in a British and Irish context, as this event has never before been seen, let alone recorded,” Whooley added.

The ESB has announced the completion of an industry-endorsed marine mammal observer (MMO) training programme to support those in the early stages of their careers in the marine environmental sector.

An additional key aim was to fill a gap in the Irish offshore wind industry’s local supply chain due to a lack of locally based MMOs on the island of Ireland.

Launched in 2023, the programme was open to recent graduates, final-year undergraduates and postgraduate students who studied or worked in the area of marine science or related disciplines.

The five successful applicants took part in industry-approved training courses including basic offshore safety induction and emergency training (BOSIET), the UK’s Joint Nature Conservation Committee (JNCC) MMO training certifications with additional Irish Guideline modules, and Offshore Energies UK (OEUK) approved medical and fit-to-train certifications.

Participants took part in MMO training provided by the Irish Whale and Dolphin Group (IWDG) and spent two nights onboard the research vessel Celtic Mist at Kilrush, Co Clare, followed by a half-day at sea.

All participants were also provided with one-year complimentary membership of the IWDG, the Marine Mammal Observer Association (MMOA) and the Institute of Marine Engineering, Science and Technology (IMarEST) with professional mentoring support and access to the Career Development Pathway.

Speaking on the completion of the programme, ESB’s Offshore Ecology Team said the programme represents a significant milestone.

“As of 2024, Ireland now has five newly trained and much-needed MMOs as a result of this initiative. Through this programme, ESB has demonstrated its commitment to supporting the marine mammal bbserver role in Ireland, nurturing local talent which will be essential in the delivery of ESB's Net Zero targets by 2040,” the team said.

“Our funding has facilitated opportunities to enhance skilled work readiness and has strengthened local talent in collaborating with local organisations such as the Irish Whale and Dolphin Group amid Ireland’s renewable energy expansion. At the heart of this Programme is the inspiration and support of young professionals seeking fulfilling careers in marine ecology and sustainable energy.”

Amy O’Reilly, one of the newly trained MMOs, shared her insights into the experience: “The ESB MMO training programme has been a wonderful opportunity and unforgettable experience for me. When I first applied, I had a history of volunteering with marine wildlife charities and was in the middle of a nine-month internship with the cetacean charity Manx Whale and Dolphin Watch. ESB recognised my passion and drive towards building a career in the marine science field.

“Some of my highlights from the programme included sleeping on board the Celtic Mist, undergoing training by the very wise and seasoned MMO Mr Patrick Lyne and, of course, escaping from a helicopter underwater in the BOSIET training.

“I am delighted to say that with this training as a foundation, I have been able to get my first MMO role with IWDG consulting, working on a short project in Dublin Port.”

Qualified MMOs are environmental professionals who specialise in monitoring marine megafauna species and ensuring the implementation of mitigation requirements during various industry operations, and they will be key components in the delivery of offshore wind projects over the coming decade.

Ireland has a unique capability given its prime location to take advantage of the potential of offshore wind, the ESB says.

ESB has announced plans to fund a marine mammal observer (MMO) training programme which is open to graduates, final-year undergraduates and postgraduate students who are studying or working in the area of marine science or related disciplines.

The aim of the programme is to assist in developing marine ecology education and skills to support successful applicants at the early stages of their careers in the marine environmental profession.

ESB will award up to five places on the MMO training programme. All applicants must be available to participate in person for training at Kilrush, Co Clare on 4-5 November. Application forms can be requested from ESB via [email protected]. The deadline for application submissions is next Thursday 12 October.

Industry-approved training courses and medicals will be funded to bring individuals up to the standard level of competency for offshore work. These courses include Basic Offshore Safety Induction and Emergency Training (BOSIET), the UK’s Joint Nature Conservation Committee (JNCC) MMO training with Irish Guideline certifications, and Offshore Energies UK (OEUK) approved medical and Fit-to-Train certifications.

The training programme is being endorsed by the Marine Mammal Observer Association, which will offer one-year complimentary affiliate membership to successful candidates and provide further advice and mentoring support for pursuing a career as an MMO.

The programme is also being endorsed by the Institute of Marine Engineering, Science and Technology (IMarEST), which will offer one-year complimentary associate membership and one-year access to its career development pathway.

The MMO training will be provided by the Irish Whale and Dolphin Group (IWDG) and will include classroom-based training, two nights’ accommodation and a half-day at-sea experience onboard the research vessel Celtic Mist. The IWDG will also offer one-year complimentary membership to programme participants.

The ESB’s Offshore Ecology Team said: “As we continue with our drive at ESB to deliver offshore wind projects as part of our Net Zero by 2040 strategy, we are committed to promoting the MMO role in Ireland, and increasing the number of qualified and experienced local professionals that will play such an important role in the future of the industry.

“Training programmes such as this will not only add to the creation of employment opportunities but will also contribute positively to help protect species as Ireland develops offshore renewable wind energy.”

Simon Berrow, chief executive of the IWDG said: “Over the last 30 years the IWDG has been at the forefront of whale and dolphin conservation in Irish waters. Now, with increasing pressures on our seas, especially the coastal zone, there is more demand than ever for trained and experienced marine mammal mitigation experts.

“The IWDG is delighted to be working in collaboration with the ESB to provide pathways to joining the offshore industry in an environmental capacity, to ensure the continued safeguarding of marine mammals in Irish waters.”

Ashleigh Kitchiner, chair of the Marine Mammal Observer Association said: “MMOA believes that investing in developing emerging professionals is vital for the growth and sustainability of our industry. We are confident that this MMO Training Programme coupled with our endorsement and support will contribute to the success of each candidate.”

Gwynne Lewis, chief executive of IMarEST said: “Nurturing the next generation of marine professionals and ensuring their access to the resources, networks and educational opportunities essential for their development is central to our work. It is vital that we inspire, encourage and support young people to want to have a rewarding career as marine professionals.”

The Shannon Estuary’s resident population of bottlenose dolphins could be under threat from plans to transform the area into a green energy hub, a conservation group fears.

Plans revealed last month in the final report of the Shannon Estuary Economic Taskforce envisage the delivery of up to 30GW of power from offshore wind energy projects in the estuary by the year 2015.

But according to the Irish Examiner, the news has prompted concern from the Irish Whale and Dolphin Group (IWDG) for the status of the estuary’s protected and unique dolphins.

Marine wildlife such as dolphins are especially sensitive to noise from human activity, such as that which would be involved in the construction and maintenance of offshore wind farms and other green energy infrastructure.

“We are lucky to have these dolphins, they are unique and it would be a tragedy if they were not there anymore in 30 years,” said the IWDG’s Dr Simon Berrow — who added that he has yet to receive a response after reaching out to Taoiseach Leo Varadkar, Environment Minister Eamon Ryan and the taskforce.

A fin whale found stranded near Ballinskelligs, Co Kerry at the weekend will not be subject to a post-mortem examination to determine its cause of death, the Irish Whale and Dolphin Group (IWDG) has said.

The whale was visited by IWDG strandings officer Stephanie Levesque under the Deep Diving and Rare species Investigation Programme (DDRIP).

DDRIP was initiated by the IWDG in 2022 in response to a well-documented increase in recent years in cetacean stranding records reported through the IWDG’s stranding scheme.

“Unfortunately this individual was too decomposed for a full post-mortem,” the IWDG said. “Stephanie collected a number of samples useful for biological studies but [was] not able to establish cause of death.

The whale was a male measuring 19 metres in length which would have made it not fully grown. Samples of skin, blubber and baleen were taken, the group added.

As for next steps, the IWDG says that Kerry County Council is intending to let the remains rest in situ as it is on private land in a secluded area.

The Nautical Institute is hosting a free webinar: Minimising Whale Strikes, Enhancing Mariners' Awareness of these Majestic Creatures which is to be held on Wednesday 15th February (9.00-10.30 GMT).

Seafarers have a love of the oceans and take great joy from sharing the environment with marine life. In fact mariners and shipping companies are often considered protectors of the oceans as can be seen by the huge efforts being made by individuals and the industry as a whole to prevent pollution at sea.

Sadly, despite our best efforts, strikes on marine mammals such as whales and dolphins continue to have an impact.

This Nautical Institute webinar seeks to explore the risk of whale strikes, help seafarers understand the nature of these mammals and identify how, with a bit of awareness, we can avoid striking them inadvertently and reduce harm against these magnificent animals which share our lives.

The following webinar Speakers are: MSC Vice President of Sustainability, MSC Mediterranean Shipping, Stefania Lallai; Dr Simon Berrow, Chief Science Officer and CEO of Irish Whale and Dolphin Group (IWDG); Sibéal Regan, IWDG Education and Outreach Officer; and National Geographic Explorer, Dr Rui Prieto, to discover the steps we can take to avoid whale strikes.

The free webinar from The Nautical Institute will be interactive, inviting feedback and questions from attendees and will provide a certificate of participation to all those who attend.

The Nautical Institute is a non-governmental organisation (NGO) with consultative status at the International Maritime Organization (IMO).

Our aim is to promote professionalism, best practice and safety throughout the maritime industry and to represent the interests of our members.

Irish Whale & Dophin Group (Survey Weeks)

The IWDG was founded in 1990 to establish an All-Ireland sighting and stranding scheme and to campaign for the declaration of Irish territorial waters as a whale and dolphin sanctuary.

For further information visit the IWDG website, noting that dates for their survey weeks are now open for those to join them on board their research vessel, the RV Celtic Mist.

The Irish Whale and Dolphin Group (IWDG) has combed through years of accumulated images to make a start on its new photo identification catalogue for fin whales in Irish waters.

And the group is calling on anyone with good-resolution images of the often elusive cetaceans to submit them to the catalogue for appraisal and potential matching.

“It only takes one strong image to reveal an animal’s identity,” IWDG sighting officer Pádraig Whooley says, “and in time this citizen science resource should begin to tell us more about the life histories of the wider cohort that arrive annually along the Irish South Coast most years during May.”

Whooley explains that recording of fin whales in Ireland — historically the more dominant of Ireland’s two large baleen whale species — had taken a backseat to that of the larger, more easily photographed humpback whales which began arriving in greater numbers a decade ago.

Another reason for this shift in emphasis, Whooley says, was the “international significance” of Ireland’s rising numbers of a marine wildlife species, in humpbacks, that has been more susceptible to commercial exploitation.

In recent weeks, however, Whooley says the time was right to revisit the IWDG’s trove of fin whale images which he and Andrew Malcolm have “whittled them down” to a starting set of “53 well-marked individuals, several of whom have been recorded over multiple years”.

“As with the humpback catalogue, these animals have been allocated unique references with associated sightings histories and are stored on a Google drive for ease of matching new images and sharing with colleagues both at home and overseas,” Whooley adds.

It’s hoped to grow this collection with contributions to the public to [email protected]. The IWDG asks that submissions be of at least medium to high resolution, sharp and shot within 100 metres of the focal animal. Especially desired are photos that show “a well-marked dorsal fin or linear scars, blemishes, signs of ship-strike injuries, entanglement marks etc” that will ease identification.

“Given the nature of fin whales and what appears to be declining numbers in Irish waters, this catalogue will no doubt throw up many challenges in the years ahead, but we’re confident there will also be some fascinating discoveries that will help inform future management plans for the largest whale in our coastal waters,” Whooley says.

“As with the humpbacks, one of the first questions we’ll be hoping to answer is, where are their breeding grounds? It’s remarkable that thus far this vital piece of ecological information has eluded whale researchers… perhaps the Irish fin whale catalogue will help solve this mystery?”

An abridged version of the fin whale catalogue will be made available on the IWDG website for citizen scientists to try to match any fin whales they’re fortunate to encounter.

Despite lower attendance and a reduced sighting rate, the Irish Whale and Dolphin Group (IWDG) says it is “delighted” with the return of its All-Ireland Whale Watch Day last month.

Held on Saturday 20 August during Heritage Week and for the first time since 2019, on account of the COVID pandemic, this year’s event saw an overall decline in attendance (-38% on 2019) and fewer cetacean sightings (33% of sites compared to 58% in 2019).

IWDG sightings officer Pádraig Whooley, who organised the event, suggested that a confluence of factors — from windy conditions on the day to the legacy of the pandemic and even holidays abroad — may have affected the turnout.

In addition, the poor sea state at many watch sites would have affected the sighting rate, with the best results at Clogherhead in Co Louth (two dolphin species and four harbour porpoises) and Howth Head in north Co Dublin (10 harbour porpoises). No whales were recorded at any of the 18 sites.

But some 530 marine wildlife enthusiasts made a day of it around the Irish coast, and Whooley is optimistic about the future of the initiative.

“We hope that among those who attended, there will be some new members and dedicated whale watchers who are willing to volunteer some of their time and energy in furthering our understanding of the whales and dolphins that live in Irish coastal waters,” Whooley said.

“Our challenge, post-pandemic, is to find new and innovative ways to rebuild this important natural history event and so we may explore the potential for moving it to May in 2023 to coincide with Biodiversity Week.”

Aquaculture Information

Aquaculture is the farming of animals in the water and has been practised for centuries, with the monks farming fish in the middle ages. More recently the technology has progressed and the aquaculture sector is now producing in the region of 50 thousand tonnes annually and provides a valuable food product as well as much needed employment in many rural areas of Ireland.

A typical fish farm involves keeping fish in pens in the water column, caring for them and supplying them with food so they grow to market size. Or for shellfish, containing them in a specialised unit and allowing them to feed on natural plants and materials in the water column until they reach harvestable size. While farming fish has a lower carbon and water footprint to those of land animals, and a very efficient food fed to weight gain ratio compared to beef, pork or chicken, farming does require protein food sources and produces organic waste which is released into the surrounding waters. Finding sustainable food sources, and reducing the environmental impacts are key challenges facing the sector as it continues to grow.

Salmon is the most popular fish bought by Irish families. In Ireland, most of our salmon is farmed, and along with mussels and oysters, are the main farmed species in the country.

Aquaculture in Ireland

  • Fish and shellfish are farmed in 14 Irish coastal counties.
  • Irish SMEs and families grow salmon, oysters, mussels and other seafood
  • The sector is worth €150m at the farm gate – 80% in export earnings.
  • The industry sustains 1,833 direct jobs in remote rural areas – 80% in the west of Ireland
  • Every full-time job in aquaculture creates 2.27 other jobs locally (Teagasc 2015)
  • Ireland’s marine farms occupy 0.0004% of Ireland’s 17,500Km2 inshore area.
  • 83% of people in coastal areas support the development of fish farming
  • Aquaculture is a strong, sustainable and popular strategic asset for development and job creation (Foodwise 2025, National Strategic Plan, Seafood
  • Operational Programme 2020, FAO, European Commission, European Investment Bank, Harvesting Our Ocean Wealth, Silicon Republic, CEDRA)
    Ireland has led the world in organically certified farmed fish for over 30 years
  • Fish farm workers include people who have spent over two decades in the business to school-leavers intent on becoming third-generation farmers on their family sites.

Irish Aquaculture FAQs

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants, and involves cultivating freshwater and saltwater populations under controlled conditions- in contrast to commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrate fish farming and plant farming.

About 580 aquatic species are currently farmed all over the world, according to the UN Food and Agriculture Organisation (FAO), which says it is "practised by both some of the poorest farmers in developing countries and by multinational companies".

Increasing global demand for protein through seafood is driving increasing demand for aquaculture, particularly given the pressures on certain commercially caught wild stocks of fish. The FAO says that "eating fish is part of the cultural tradition of many people and in terms of health benefits, it has an excellent nutritional profile, and "is a good source of protein, fatty acids, vitamins, minerals and essential micronutrients".

Aquaculture now accounts for 50 per cent of the world's fish consumed for food, and is the fastest-growing good sector.

China provides over 60 per cent of the world's farmed fish. In Europe, Norway and Scotland are leading producers of finfish, principally farmed salmon.

For farmed salmon, the feed conversion ratio, which is the measurement of how much feed it takes to produce the protein, is 1.1, as in one pound of feed producing one pound of protein, compared to rates of between 2.2 and 10 for beef, pork and chicken. However, scientists have also pointed out that certain farmed fish and shrimp requiring higher levels of protein and calories in feed compared to chickens, pigs, and cattle.

Tilapia farming which originated in the Middle East and Africa has now become the most profitable business in most countries. Tilapia has become the second most popular seafood after crab, due to which its farming is flourishing. It has entered the list of best selling species like shrimp and salmon.

There are 278 aquaculture production units in Ireland, according to Bord Iascaigh Mhara (BIM) *, producing 38,000 tonnes of finfish and shellfish in 2019 and with a total value of €172 million

There are currently almost 2,000 people directly employed in Irish aquaculture in the Republic, according to BIM.

BIM figures for 2019 recorded farmed salmon at almost 12,000 tonnes, valued at €110 million; rock oysters reached 10,300 tonnes at a value of €44 million; rope mussels at 10,600 tonnes were valued at €7 million; seabed cultured mussels at 4,600 tonnes were valued at €7 million; "other" finfish reached 600 tonnes, valued at €2 million and "other" shellfish reached 300 tonnes, valued at €2 million

Irish aquaculture products are exported to Europe, US and Asia, with salmon exported to France, Germany, Belgium and the US. Oysters are exported to France, with developing sales to markets in Hong Kong and China. France is Ireland's largest export for mussels, while there have been increased sales in the domestic and British markets.

The value of the Irish farmed finfish sector fell by five per cent in volume and seven per cent in value in 2019, mainly due to a fall on salmon production, but this was partially offset by a seven per cent increased in farmed shellfish to a value of 60 million euro. Delays in issuing State licenses have hampered further growth of the sector, according to industry representatives.

Fish and shellfish farmers must be licensed, and must comply with regulations and inspections conducted by the Sea Fisheries Protection Authority and the Marine Institute. Food labelling is a function of the Food Safety Authority of Ireland. There is a long backlog of license approvals in the finfish sector, while the Department of Agriculture, Food and Marine says it is working to reduce the backlog in the shellfish sector.

The department says it is working through the backlog, but notes that an application for a marine finfish aquaculture licence must be accompanied by either an Environmental Impact Statement (EIS) or an Environmental Impact Assessment Report (EIAR). As of October 2020, over two-thirds of applications on hand had an EIS outstanding, it said.

The EU requires member states to have marine spatial plans by 2021, and Ireland has assigned responsibility to the Department of Housing, Planning and Local Government for the National Marine Planning Framework (NMPF). Legislation has been drawn up to underpin this, and to provide a "one stop shop" for marine planning, ranging from fish farms to offshore energy – as in Marine Planning and Development Management Bill. However, the Department of Agriculture, Food and Marine confirmed last year that it intends to retain responsibility for aquaculture and sea-fisheries related development – meaning fish and shellfish farmers won't be able to avail of the "one stop shop" for marine planning.

Fish and shellfish health is a challenge, with naturally occurring blooms, jellyfish and the risk of disease. There are also issues with a perception that the sector causes environmental problems.

The industry has been on a steep learning curve, particularly in finfish farming, since it was hailed as a new future for Irish coastal communities from the 1970s – with the State's Electricity Supply Board being an early pioneer, and tobacco company Carrolls also becoming involved for a time. Nutrient build up, which occurs when there is a high density of fish in one area, waste production and its impact on depleting oxygen in water, creating algal blooms and "dead zones", and farmers' use of antibiotics to prevent disease have all been concerns, and anglers have also been worried about the impact of escaped farmed salmon on wild fish populations. Sea lice from salmon farmers were also blamed for declines in sea trout and wild salmon in Irish estuaries and rivers.

BIM says over 95% of all salmon farmed in Ireland are certified organic. Organically grown salmon are only fed a diet of sustainable organic feed. They are also raised in more spacious pens than traditional farmed salmon. The need to site locations for fish farms further out to sea, using more robust cages for weather, has been recognised by regulatory agencies. There is a move towards land-based aquaculture in Norway to reduce impact on local ecosystems. The industry says that antibiotic use is declining, and it says that "safe and effective vaccinations have since been developed for farmed fish and are now widely used". Many countries are now adopting a more sustainable approach to removing sea lice from salmon, using feeder fish such as wrasse and lumpsucker fish. Ireland's first lumpsucker hatchery was opened in 2015.

Ireland's first lumpsucker hatchery was opened in 2015.

Yes, as it is considered to have better potential for controlling environmental impacts, but it is expensive. As of October 2020, the department was handling over 20 land-based aquaculture applications.

The Irish Farmers' Association has represented fish and shellfish farmers for many years, with its chief executive Richie Flynn, who died in 2018, tirelessly championing the sector. His successor, Teresa Morrissey, is an equally forceful advocate, having worked previously in the Marine Institute in providing regulatory advice on fish health matters, scientific research on emerging aquatic diseases and management of the National Reference Laboratory for crustacean diseases.

BIM provides training in the national vocational certificate in aquaculture at its National Fisheries College, Castletownbere, Co Cork. It also trains divers to work in the industry. The Institute of Technology Carlow has also developed a higher diploma in aqua business at its campus in Wexford, in collaboration with BIM and IFA Aquaculture, the representative association for fish and shellfish farming.
