In a historic and groundbreaking event, a tagged whale shark has returned to the Galapagos after an incredible ~7 month (210-day) journey across the Pacific Ocean.

Elise #262715 was tagged on June 21st at Darwin Arch by divers from the Galapagos Whale Shark Project. This adult female whale shark, measuring between 10 and 11 meters, was previously unknown to the Wildbook for Sharks, marking this as her first recorded sighting in the Galapagos.

Elise’s remarkable journey, now covering >18,000 kilometres (surface track) over the course of just under 11 months, illustrates the vast distances whale sharks are capable of travelling. 

Her path initially took her north-westward, travelling a straight-line distance of 4,226 kilometres from where she was tagged at Darwin Island (Lat: 1.665178°, Lon: -91.987012°). This underscores the urgent need for the establishment of more marine protected areas and the enforcement of high seas policies to safeguard migratory species like whale sharks.

Currently, Elise has been observed off the west and south sides of the Galapagos Archipelago for the past 3 months, within an upwelling zone, suggesting potential foraging behavior. This new movement could reveal previously unknown habitat use in the Galapagos for whale sharks, providing vital insights into their behaviour in the region. She has now headed north and the hope is that her track will reach the 1 year mark and she might soon return to Darwin Arch where she was tagged, at that time, creating a truly historic event.

The Galapagos Whale Shark Project team, with the Galapagos National Park, will continue to track Elise and gather data to enhance our understanding of whale shark habitat use and migration patterns. 

The team is currently preparing for the upcoming field expedition which will head out to Darwin Island mid-June. There, they will carry out further tagging, photo ID and Blood draw, as well as the collection of DNA / tissue samples for genetics studies.

This research is critical for developing effective conservation strategies to protect these magnificent creatures throughout their life cycles and this work is made possible by the kind donations of our guests onboard the G Expedition and the support of Planeterra.

Since 2018, the Planeterra Ocean Health Fund has supported the work of the Royal Society for the Protection of Birds (RSPB) and BirdLife International’s Albatross Task Force to combat incidental capture of marine wildlife in fisheries around the world. To celebrate 20 years of the Albatross Task Force, we explore how Planeterra are helping scale up these measures to support work in the High Seas tuna fisheries. Oli Yates, Head of BirdLife International provides an update below.

Fisheries are an essential source of income and food security for millions worldwide, yet incidental capture in fishing gear poses a critical threat to marine biodiversity and represents the greatest at-sea threat to many seabird populations. This impact is particularly severe for albatrosses and large petrels, whose migratory life cycles expose them to fishing fleets across multiple Exclusive Economic Zones and in the shared waters of the High Seas – the immense area of ocean outside national jurisdictions. Populations are declining rapidly as these slow-breeding birds are tragically caught on hooks during tuna fishing operations and too often these birds do not survive – an impact known as ‘seabird bycatch’.

Formed in 2004, the RSPB’s Albatross Task Force (ATF) has bridged the gap between the scientific community, policymakers and the fishing industry to reduce albatross bycatch and improve the conservation status of these threatened animals.

The ATF teams have made so many remarkable and vital contributions to seabird conservation over the last 20 years. At-sea trials and implementation of bycatch mitigation measures in trawl and longline fisheries have led to astounding bycatch reductions – such as 98% fewer birds killed in the Namibian longline fishery, and a 99% reduction in albatross bycatch in the South African trawl fleet.

Support from the Planeterra Ocean Health Fund has helped deploy ATF staff to scale activities in the High Seas, with the potential to save thousands of seabirds per year – at least 36,000 are killed annually (this is likely to be an underestimate due to poor data) – including high-risk species like the Atlantic Yellow-nosed albatross, Grey-headed albatross, Wandering albatross and White-chinned petrels.

On the High Seas, fishing is regulated by Regional Fisheries Management Organisations (RFMOs). RFMOs require members to annually report bycatch including details of seabird and sea turtle bycatch, shark finning and implementation of conservation measures (eg. best-practice seabird bycatch mitigation measures) in areas where seabirds are present. Currently, many nations fishing in the High Seas, report extremely low levels of bycatch and no shark finning, which is unlikely given our knowledge of reports from fishery observers. Many fisheries have cited limited availability of trained observers and scientists to collect and analyse the data from commercial fishing activities as a key barrier to reporting.

With over 1,000 vessels operating throughout most of the global ocean, Taiwan is one of the world’s most important fishing nations. One of the most lucrative species targeted is tuna, which is predominantly caught by longline fishing methods.

The RSPB is supporting the Taiwan Wild Bird Federation, Taiwanese fisheries, communities and government to educate and improve understanding of mitigation measures to help protect threatened seabirds and promote sustainably sourced seafood.  Scott Pursner is leading our efforts in Taiwan to support the process of engagement across the spectrum, from government to vessel owners and captains to major international tuna traders. External market access is an important incentive in Taiwan and efforts are underway to strengthen the ability of companies to demonstrate uptake of conservation measures. This is particularly true for those working towards Marine Stewardship Council certification for their vessels.

Our ATF teams work directly with fishers to assess the risk posed by target fishing fleets by collecting data on vessels and supporting the implementation of effective mitigation measures that can reduce seabird bycatch to negligible levels. The measures range from simply fishing at night when fewer birds are around, to using so-called ‘bird-scaring lines’ which act as scarecrows behind fishing vessels, spooking birds out of harm’s way. In Taiwan, we are not able to join the vessels as they spend months at-sea. Instead, we are deploying an in-port outreach approach to ensure there are locally sourced options to provision Best Practice mitigation measures for the fleet. Where mitigation is available, like bird-scaring lines, we are providing advice on the design and materials. Where mitigation is not available, we are assisting in the sourcing of crew-safe measures such as “sliding leads” that prevent potential injury at-sea.

Our teams also work closely with government representatives, helping secure national regulations, requiring vessels to use such ‘bycatch mitigation measures’. In Taiwan, we are promoting and facilitating awareness of RFMO conservation measures that Taiwan has committed to incorporating into national regulations.  

At a grassroots level, key to ATF success has been outreach activities including the training of fishing industry personnel (fishers, observers and compliance officers), bycatch education workshops at local schools and the production of reference materials (videos, leaflets) to supplement the wider programme. In Taiwan, we are currently adapting this approach to work within the local culture and structure, liaising with the local fishery observer agency, supporting capacity building activities so that lessons learnt in ATF teams are effectively transferred and incorporated into Taiwanese fleets.

The resultant relationships built with key stakeholders in the fishing industry and national authorities around the world puts the ATF in a unique position to help support Taiwanese fleets transition towards full implementation of bycatch mitigation measures on tuna vessels. 

On behalf of the RSPB and Taiwan Wild Bird Foundation, we are grateful for the help from the Planeterra Ocean Health Fund to support Taiwanese fisheries, communities and government to educate and improve understanding of mitigation measures to help protect threatened seabirds and promote sustainably sourced seafood.

One of the most harmful forms of marine debris is abandoned, lost, and discarded fishing gear—also known as ghost gear.

Planeterra’s Ocean Health Fund is proud to support Ocean Conservancy’s Global Ghost Gear Initiative® (GGGI), a leading alliance dedicated to solving this issue through practical, replicable, and sustainable solutions.

Here are some of the GGGI’s key impacts from the past year:

• Removing Ghost Gear from Sensitive Marine Areas.
• Cross-Border Collaboration. The North American Net Collection Initiative , led by GGGI, collects old fishing nets in Mexico, the U.S., and Canada. So far, over 566,000 pounds of nets have been collected and mostly recycled into new products.
• Raising awareness among fishers and the public. GGGI provides hands-on training for fishers and runs public education campaigns. Media appearances like “Oceans Haunted By Ghost Gear” and “Ghost Gear is polluting the Chesapeake Bay and oceans around the world” have helped spread awareness to wider audiences.
• Advocating for a strong global plastics treaty.

Another important part of this effort is the Joanna Toole Internship, which supports early-career women pursuing ocean conservation. Hosted by Ocean Conservancy and the Center for Coastal Studies (CCS), the internship is generously funded by Planeterra.

To date, three interns have completed the program—including Wilson Haims, the 2024 Joanna Toole Intern. Her experience highlights the depth and impact of this unique opportunity:

Meet Wilson Haims: 2024 Joanna Toole Intern

My name is Wilson Haims and I am the 2024 Joanna Toole Intern. I am from Maine and graduated from Wellesley College with a degree in Environmental Studies in 2023. 

As part of my undergraduate degree, I participated in an ocean and coastal studies program directed by Williams College called Williams-Mystic. There, I honed my interest in marine issues and gained more experience on the water. By the time I graduated, I had plans to work as a marine educator at the Center for Alaskan Coastal Studies. 

In Alaska, I grew immensely as a naturalist, educator, and as a person. I worked from the Homer Harbor and regularly interacted with the commercial, sport, and subsistence fishermen. As the summer progressed, I had the opportunity to go salmon fishing and I became increasingly compelled by human relationships to the ocean and our reliance on its resources; fishing merges the concepts of tradition, culture, subsistence, science, connection to nature, and technique in a way that is challenging to find in other professions or recreational activities.

Over the past three months, I had the opportunity to work with the Marine Debris and Plastics Program at the Center for Coastal Studies in Provincetown, Massachusetts. During my time in Provincetown I collaborated with local fishermen to recover lost and abandoned fishing gear from Cape Cod Bay, assisted in leading a week-long fishing gear removal effort from the beaches on Cuttyhunk Island, and helped coordinate a residency for students from Cornell University to engage with ghost gear and marine debris related issues. 

Beyond these larger projects, I also participated on research cruises with the Right Whale Research team, the Marine Animal Entanglement Response team and had the chance to observe a side-scan sonar cruise. I look forward to translating my experience in ghost gear related field work to the Global Ghost Gear Initiative. 

When I discovered the Joanna Toole Internship, I was struck by how unique the opportunity is: I had the chance to recover ghost gear from Cape Cod Bay, working directly in collaboration with fishermen, and now get to zoom out and consider these issues on a global scale. 

Beyond this position’s comprehensive approach, I am fascinated by how collaborative this work can be and who it speaks to. At the Center for Coastal Studies I worked with artists, scientists, environmentalists, fishermen, volunteers, and a fishing net recycler. In my interactions with these individuals, I quickly learned that many of them claim more than just one of these titles. 

It is my hope and intention to bring what I have learned from these diverse perspectives and incorporate their insight into how I approach this work. I look forward to exploring where the second half of this internship takes me.
