Looking beyond the can - the importance of tuna fisheries

Part 2: The Indian Ocean

The Indian Ocean Tuna Commission manages the second most lucrative tuna fishery in the world. More than half of the tuna catches in the Indian Ocean come from small-scale fisheries, which are often characterised by a lack of data and information. Overall, the Indian Ocean faces many complex and unique challenges.

In this episode, we talk to four experts from the region who have been actively engaged in shaping the Indian Ocean tuna fisheries.

Guests:

Adam Ziyad – Chair of the Indian Ocean Tuna Commission

Dr Paul de Bruyn – Executive Secretary of the Indian Ocean Tuna Commission

Umair Shahid – Indian Ocean Tuna manager for WWF

Doreen Simiyu – Coordinator of the Indian Ocean Tuna Forum (SWIOTUNA)

Looking beyond the can - the importance of tuna fisheries

Part 1: The Western and Central Pacific Ocean 

The management of the tuna species is important for the livelihoods and food security of millions of people.  

This is especially true for the tuna caught in the Western and Central Pacific Ocean, which accounts for more than half of the global tuna catch. 

In this episode, we will hear from four experts who have dedicated their lives to ensuring that tuna fisheries in the Western and Central Pacific are managed sustainably.  

Guests:  

Professor Transform Aqorau – Vice Chancellor of the Solomon Islands National University 

Francisco Blaha – Fisheries Consultant

Episode 5- Access and Benefit Sharing of Marine Genetic Resources

Series on Stakeholders in BBNJ: PART 3 Scientist

We don’t yet know what the deep sea holds – but what we know is that benefits need to be shared fairly and equitably. A new Ocean Treaty changes the status quo of access and benefit sharing of marine genetic resources (MGRs) of areas beyond national jurisdiction. Yet, many questions remain about the nitty-gritty details of implementation.

• What are marine genetic resources and their digital sequence information?

• How can benefits be shared fairly and equitably?

• What are the most urgent issues to negotiate in upcoming meetings of the United Nations?

In this episode we meet Fran Humphries, Associate Professor at Griffith University, an expert on Access and Benefit Sharing of Marine Genetic resources. She guides us through ocean equity issues about sharing the genetic material of the deepest parts of the ocean.

Episode 4 – Civil Society

Series on Stakeholders in BBNJ: PART 2 Civil Society

It’s not just government delegations that participate in ocean negotiations. There are countless non-governmental organisations (NGOs) who observe and advise in the negotiations and support implementation.  These NGOs have real concerns about protecting marine biodiversity and increasingly campaign about ocean equity.

• What is the role of civil society in the BBNJ negotiations?

• Which new bodies will be established under the new agreement?

• How does the design of the committees carry implications for ocean equity?

In this episode, we talk to civil society and meet Rebecca Hubbard, the director of the High Seas Alliance – a global Alliance of more than 60 NGOs and the International Union for Conservation of Nature (IUCN).

Episode 3 – Small Island States

Series on Stakeholders in BBNJ

PART 1 : Small Island States

Small Island States may be small when it comes to land – but are often big ocean states.

They are particularly vulnerable, as they depend on the ocean for their livelihoods and are among the most affected by climate change.

In the negotiations, they often form negotiating blocs to speak in one voice. Outcomes of negotiations for the new Ocean Treaty affect us all – but the direct impact of the treaty is especially felt in the case of Small Island States.

• What are challenges for Small Island States in the negotiations and implementation of the treaty?

• How will be ensured that they can shape new High Seas institutions in the long-term?

• And will the new ocean treaty shift power imbalances in ocean governance?

In this episode we hear from Angelique Pouponneau, the lead negotiator of the Alliance of Small Island States (AOSIS) what ocean equity means for Small Island States.

After decades of negotiations and a 36 hour-long meeting at the United Nations in New York, countries from around the world agreed to a new Ocean treaty in 2023. The landmark treaty governs Biodiversity of Areas Beyond National Jurisdiction – what we call, BBNJ.  A big task: It does not only protect marine life in the High Seas, but also ensures that benefits are shared fairly and equitably amongst all. The high seas, beyond national borders, cover two-thirds of the surface and nearly 95 percent of the volume of the entire ocean. But the treaty has not yet been ratified into domestic law by the 60+ countries needed to make it legally binding. This episode explores what happens next and how decisions now have real implications for ocean equity.

• What is still left to negotiate after the treaty has been adopted?

• How can all voices be heard for decisions about international areas?

• And what needs to happen now for this Agreement to come into life?

Join us and special guests Janine Felson and Adam McCarthy, the co-chairs of the Preparatory Commission for the entry into force of the BBNJ agreement.

The episode is published ahead of the First Preparatory Commission meeting April 14-25, 2025, in New York.

70 % of the Earth’s surface is Ocean. Beneath the surface lies a complex web of global governance. Who decides how to manage the ocean in a way that is fair and equitable to both the marine environment and humans who rely on the sea for their livelihoods?

Episode 1 of ‘Negotiating the Ocean’ explores the idea of Ocean Equity and how it can be applied to the high-level international talks governing and managing the ocean and its resources. We meet ANCORS researchers who work on different aspects of Ocean Equity, including fisheries, climate change, pollution, deep sea mining, renewable energy, and more.

We ask the big questions:

• Who gets to fish, where, and how much?
• How is climate change being factored into decision-making?
• How are responsibility and costs for environmental protection shared between developed and developing countries?
• How can benefits from minerals and genetic material be shared equitably?
• Who gets a seat at the decision-making table and is a diversity of voices being heard?
• And, what is the role of future generations and planetary health?

Join us for this first episode of negotiating the ocean and meet a collective of ANCORS experts passionate about reshaping the way global society relates to and looks after the Ocean.

The ANCORS Ocean Equity Podcast Negotiating the Ocean peeks below the surface of international ocean governance. We take you behind the scenes of ocean negotiations on biodiversity, fisheries and deep-sea mining and ask the big questions around equity and social justice.

Marine biodiversity, fisheries, deep-sea mining, climate change, and pollution are all inherently international issues and require cooperation at multiple levels. Negotiating the Ocean from ANCORS is your audio guide to navigate these high seas negotiations.

Each episode we’ll talk to experts around the world about the challenges facing the ocean and how the global community is trying to address them. Above all, we’ll look at these issues through the lens of equity, which means the process needs to be inclusive of different voices –because outcomes of the negotiations affect us all. 

So, whether you live by the ocean or far away, plan to attend the upcoming negotiations as part of a delegation or are an ocean enthusiast – this podcast is for you.
