Scottish fishers successfully trial innovative fishing gear to prevent whale entanglement in ropes

A breakthrough collaborative project with creel fishers has successfully trialled a simple and relatively low-cost solution to the problem of whale entanglement that could be rolled out internationally saving many whales and sharks.

The project led by marine charity Whale and Dolphin Conservation (WDC),and funded by the Scottish Government Nature Restoration Fund managed by NatureScot, trialled the use of specially designed rope in Scottish pot fisheries that sinks rather than floats.

The rope currently used in the fishery is buoyant and forms floating loops in the water rather than lying on the seabed.

These loops can be several metres high and have been found to entangle whales and other marine animals such as basking sharks. Previous studies had found the majority of whales and basking sharks entangled in static fishing gear (pots, or creels as they are known in Scottish fisheries) are caught in this floating groundline rope linking a line of creels together.

It is estimated that an average of 6 humpback whales, 30 minke whales, and 29 basking sharks become entangled annually.

Where entanglement type was known, 83% of minke and 50% of humpback whales, and 76% of basking sharks were caught in groundlines between creels. If there are no large floating rope loops, then whales and sharks cannot become entangled in them.

Over a period of 18 months 15 fishing vessels targeting langoustine and crabs from the Inner Sound and Sound of Sleat area east of the Isle of Skye replaced floating rope in their creel groundlines with sinking rope to assess whether there were any problems with using it. Fishers reported back each time they hauled their gear, and details of over 1500 hauls were logged in the trial.

Trials were needed to determine whether it was practical for fishers to use this sinking rope. Problems which were anticipated such as snagging, or being difficult to handle were very rare.

The fishers involved in the trial reported positive experiences with using the rope, and there were no impacts on the seabed. 

Susannah Calderan, who managed the project for WDC, said; ‘The Scottish inshore creel fishery plays an important economic and community role in rural coastal areas in Scotland. Resolving the issue of entangling whales would be a major step forward in fisheries management as well as animal conservation and welfare.

‘It’s been great working with the Inner Sound fishers on this project, and we have an almost-unique opportunity to make a real impact on whale bycatch. We now have to move to the next step, which is consulting with other fishers around Scotland and with the Government to understand the possible options for implementing sinking rope more widely.’

Sinking groundline represents a simple, relatively low-cost option to greatly reduce entanglement risk.

The very successful, bottom-up, partnership approach with Scottish creel fishers and the Scottish Creel Fishermen’s Federation (SCFF) demonstrated the importance of collaborative approaches to address complex conservation and management issues. Its implications are key to supporting the Scottish Government’s commitment to reduce incidental bycatch in fisheries.

Bally Philp from SCFF, who participated in this trial, said ‘This trial has shown there can be win-win outcomes for both fishermen and marine life, and we’re all working together to achieve this’.

South West Tenerife becomes Europe’s first Whale Heritage Site

A wee bit away from North Edinburgh, but a destination to dream about if we ever have foreign holidays again …

South West Tenerife has become Europe’s first Whale Heritage Site, a global certification developed by the World Cetacean Alliance and supported by World Animal Protection, that recognises outstanding destinations for responsible and sustainable whale and dolphin watching.

The site at Tenerife-La Gomera Marine area offers tourists an easy way to select responsible whale and dolphin watching in the wild and gives the travel industry a way to move away from selling wildlife entertainment activities and select ethical practices instead.

Tenerife is popular with UK tourists and a famous spot to see whales and dolphins in the wild. The accreditation of the site in South West Tenerife recognises the community´s commitment to respect and celebrate these animals. Twenty-eight cetacean species can be found in the island’s waters including short-finned pilot whales, sperm whales and bottlenose dolphins.

This site and one in Dana Point, California, USA also announced today, join the only other two Whale Heritage Sites in the world: The Bluff, South Africa and Hervey Bay, Australia.

“Whale Heritage Sites play a vital role in showing a responsible and sustainable alternative to wildlife entertainment activities,” said Katheryn Wise, Wildlife Campaign Manager at World Animal Protection. 

“While travel is temporarily on hold for most of us, when it does resume it is up to all of us to make responsible choices. These sites will help promote tour operators who protect the welfare of marine wildlife while offering tourists the chance to experience these animals free and thriving in the wild, where they belong.”

Elizabeth Cuevas, Whale Heritage Sites Manager at World Cetacean Alliance, said: “The designation of Europe’s first Whale Heritage site is a wonderful step forward for responsible tourism.

“We believe the site is fast becoming a world leader in sustainable whale and dolphin watching and this certification will help the local community by recognizing responsible whale watching practices supported by the latest research and conservation efforts.”

Becoming a Whale Heritage Site will ensure that visitors are contributing to destinations that celebrate their natural heritage, protect marine wildlife and build a connection between local residents and sea life.

In addition to the opportunity to observe cetaceans, vibrant festivals and other events celebrate the marine environment and provide education and inspiration for tourists and locals alike.

Tenerife-La Gomera Marine area´s location in tourist hot-spot Tenerife is popular with the island’s 6 million annual visitors1. The importance of the tourist industry to the local area is reflected in the local and national regulatory frameworks, which provide formal protection of the marine ecosystem, with two Special Areas of Conservation (SACs) and a strong legislative framework protecting cetaceans.

To qualify for Whale Heritage Site accreditation, candidate destinations must meet set criteria which recognises their commitment to cetacean conservation through responsible wildlife interactions and sustainability. These include:

  • Encouraging respectful human-cetacean coexistence
  • Celebrating cetaceans
  • Environmental, social and economic sustainability
  • Research, education and awareness

In meeting Whale Heritage Site criteria, sites must take into account information relating to the relevant local cetacean populations including their status, numbers, biology, habitat, behaviour and welfare.

Scottish sculptor Michael Visocchi wins international artistic commission

  • The ‘Spirit Tables’ will represent the fall and rise of whales in the oceans of the sub-Antarctic

After a year-long search, the South Georgia Heritage Trust and the Government of South Georgia & the South Sandwich Islands are delighted to announce the winner of a major international artistic commission that was designed to highlight the environmental recovery of the stunning sub-Antarctic island of South Georgia, a UK Overseas Territory in the Southern Ocean. 

The idea of the commission was to challenge artists to find a way to tell the powerful conservation messages of South Georgia, an island that was at the centre of the whaling industry for decades, but is now a modern rarity: an eco-system in recovery and a beacon of hope for conservation activities worldwide. 

The winning artist is Scottish sculptor Michael Visocchi, with his work called ‘Commensalis – the Spirit Tables of South Georgia’. This site-specific piece will be situated on South Georgia at the Grytviken Whaling Station, with Michael’s concept drawing inspiration from a number of sources to tell the island’s powerful story. 

The artwork will be made up of three main elements that all interlink to tell the story from devastation to the recovery of whale populations in the oceans around South Georgia, and more widely.

Visually it will make a connection between the barnacles found growing on the skin of various whale species and the steel rivets which literally held together the structures and vessels that powered the whaling industry for nearly a century. It will also reference the industrial nature of the whaling station and materials used in the derelict buildings that bore witness to the processing of so many whales.  

The Key Table sets the scene through a series of rivets arranged in a Nightingale chart*. It will visualise for visitors the stark reality that 175,250 whales were processed at South Georgia between 1904 and 1966. The Key Table will help unlock the message of what will follow with the other elements of the artwork.

The Footbridge is being explored as an element of the project, once Michael has had the opportunity to visit, and crossing it will provide a moment of reflection and contemplation as visitors walk across the slipway area where thousands of whales were dragged up and processed.

It will act as a transition point from the Key Table area to the Flensing Plan – the name given to the platform where the processing took place. The Footbridge will guide visitors to the final element of the artwork – the Spirit Tables. 

The Spirit Tables are at the heart of the Flensing Plan and consist of six tables representing the six different whale species that were hunted and processed at Grytviken: Blue Whale, Fin Whale, Southern Right Whale, Sei Whale, Sperm Whale and Humpback Whale.

The Spirit Tables are punctuated by stainless steel button head rivets in various patterns, with each rivet symbolising a live whale or the spirit of a live whale. Michael’s design allows light to bounce off each rivet, illuminating the space and emitting a feeling of hope that is now evident around the waters of South Georgia following the end of whaling and the return of a number of species. 

Recent expeditions by British Antarctic Survey have resulted in an unprecedented number of sightings of both blue and humpback whales, suggesting that the waters of South Georgia are once again becoming an important summer feeding ground for both species.

The title of the artwork Commensalis is derived from the biological term commensal, which defines a biological relationship where two species benefit from one another and where neither species suffer. Michael’s artwork focuses on the commensal relationship between whales and the whale barnacle. The artwork’s title more broadly proposes whether humankind ought to aspire to have that same commensal relationship with planet earth.

On being awarded this prestigious commission artist Michael Visocchi said: “This is an enormous honour and an extraordinary opportunity to engage creatively with such an important story in a truly remarkable place. It is going to be a real privilege to work alongside the many skilled and dedicated people who are so deeply invested in South Georgia and its wildlife.

“It is very rare for an artist to have the opportunity to respond to and work in such a genuinely special place and with such a deeply emotive subject matter. I have tried to weave a sense of hope into this work in an otherwise tragic and charged location in the whaling station. The Flensing Plan was where the more brutal physical aspects of whaling took place. I hope though that future visitors will gain some insight and hope from my Spirit Tables.

“As a sculptor and maker my work has always attempted to deal with our interaction with the landscape. This is what drew me to applying for this commission in the first place. It isn’t often that ‘site specificness’ or responding to a particular context is written into a commission brief.

“I hope the scale of this work in some way evokes the majesty of these amazing creatures and the magnitude of this story about humankind’s quite often troubled relationship with other species and the environment, but also humankind’s amazing ability to steer ultimately towards enlightenment.”

The South Georgia Heritage Trust, the Scottish-based charity that has organised this artistic commission, has been working on the island in close partnership with the Government of South Georgia & the South Sandwich Islands (GSGSSI) since 2005.

Its hugely successful Habitat Restoration Project has reversed two centuries of human-induced damage to the island’s wildlife, eradicating the mice and rats that arrived as stowaways on sealing and whaling vessels from the late 18th century onwards that preyed on ground-nesting and burrowing birds.  

As a result, millions of birds reclaimed their ancestral home when South Georgia was declared rodent-free in May 2018 – the largest invasive species eradication in the world.

Alison Neil, Chief Executive of SGHT said: “We were delighted with the responses from all over the world to the commission and it was heartening that so many artists were moved by the compelling story of South Georgia and wanted to be part of making a difference.

“The competition was tough, but the entire judging panel led by Elaine Shemilt (Vice Chairman of SGHT and Professor at Duncan of Jordanstone College of Art & Design, University of Dundee), was impressed by the level of research Michael had undertaken and were struck by how his concept so effectively captured the essence of the brief, which was to shine a light of hope onto what can often seem a bleak future for our environment.

“This is just the start of the journey for SGHT and Michael, who will have the opportunity to visit South Georgia and evolve his concept once he has physically seen the site at Grytviken. 

“The era of whaling and sealing was a dark period in our planet’s history, but the tide is turning.

“Now, not only are South Georgia’s birds free from invasive rodents, but whale species are starting to recover in the seas around the island too, which thanks to the GSGSSI now encompasses a 1.24 million km2 Marine Protected Area.

“We are thrilled that this artistic commission will sit at the heart of the work we are embarking, on as part of a cultural heritage programme to tell the world more about the human story on South Georgia.”

Helen Havercroft, Chief Executive of GSGSSI and a member of the judging panel said: “The Government looks forward to working alongside Michael and our Heritage Advisory Panel to ensure that the impressive concept Michael presented works to enhance the visitor experience at Grytviken and provide that critical ‘hope’ that humankind’s ability to destroy can be repaired through collective effort and a world-class management.

“Past human activities pushed some species to the brink of extinction but today, through hard work and commitment, South Georgia is a global rarity; an ecosystem in recovery with the recently published papers on returning whales to South Georgia’s waters serving as evidence of that recovery.”

Amanda CattoHead of Visual Arts at Creative Scotland, who was also part of the judging panel, said: “Art is a really accessible and emotive way to tell powerful stories about the environment and engage people who might otherwise not be interested. The level of interest and entries to the competition demonstrates that.

“I am particularly impressed with the way the competition has been run and the quality of entries was incredible. Michael’s winning concept is exceptionally powerful and the way he proposes using the site and the materials to bring it to life is something I look forward to following as this project develops.”

Michael was due to visit South Georgia in the coming months, but due to COVID-19 this has been rescheduled to autumn 2021. Given the site-specific nature of the piece, it is imperative the artist has the chance to visit and adjust their concept accordingly, something that is particularly important for Michael who hopes to include disused materials from the whaling station in his construction.

The artwork will be permanently installed at Grytviken Whaling Station located in Cumberland Bay, South Georgia. Grytviken is the only visitor-accessible whaling station on South Georgia and receives around 10,000 visitors per year under usual circumstances.

Michael’s artwork will also be part of an outreach programme in the UK (currently under development), which may see Spirit Tables placed in a number of locations to engage a wider number of people in the story of South Georgia.

‘Acoustic camouflage’ keeps the humpback boys at bay

Napier University research focuses on female whales’ breeding ground behaviour

Female humpback whales head for deeper waters as their calves mature and use rugged seabed terrain as ‘acoustic camouflage’ to help avoid adult males looking to mate, a study by Edinburgh Napier University has found. The new study into the behaviour of the marine mammals has discovered that the mothers’ habitat choices are strongly influenced by the size and age of their calves.
