Natural Justice Podcast

In this episode, Eva van Heukelom speak with Matt Craze from Spheric Research about the growing role of AI and innovation in the salmon aquaculture industry. From optimising feed and monitoring fish health to improving transparency and operational decision-making, AI-driven tools are rapidly reshaping how salmon is farmed. We explore where these technologies are delivering real value, where the limitations still lie, and what this means for a responsible and resilient seafood sector. Question for Matt or Eva?

Part II of Eva's conversation with Actea's Jordan Miller and Trond Kristiansen dives into one of the most pressing questions for the future of aquaculture: how climate change is already reshaping farming conditions, and what that means for long-term investment decisions.Aquaculture depends entirely on environmental stability, yet ocean and freshwater systems are changing rapidly. Rising water temperatures are already pushing many species beyond their optimal growth ranges, increasing stress, slowing growth, and making fish more vulnerable to disease and parasites. At the same time, ocean acidification is weakening shellfish development, while warming waters and nutrient shifts are driving harmful algal blooms and oxygen depletion. But this episode looks ahead. Climate projections show that suitable farming zones are shifting. What may be a viable aquaculture site today could become economically unviable within decades due to temperature changes, salinity shifts, or extreme weather events. Sea level rise, stronger storms, and changing rainfall patterns further threaten infrastructure and water quality, especially in coastal and delta regions. We discuss how better data, climate modelling, and site selection can help avoid stranded investments, and why understanding both current and future environmental conditions is no longer optional - it is central to responsible aquaculture development.This episode is essential listening for investors, policymakers, and seafood professionals navigating the intersection of aquaculture, climate risk, and long-term sustainability.#sustainability #ai #climatechange #climate #climatemodeling #aquaculture #oceans #oceanintelligence #farming

In this episode of the Ocean Intelligence series, we speak with Trond (Norway) and Jordan (US) from Actea about how predictive modeling, data, and AI are transforming fisheries management in the face of climate change. Instead of reacting to shifting fish stocks, extreme weather, and environmental uncertainty, Actea’s technology helps fisheries anticipate changes and make more proactive, informed decisions.We explore how data-driven insights can improve resilience, support sustainable fishing practices, and bridge the gap between science, policy, and industry. This conversation highlights the growing role of ocean intelligence and digital tools in shaping the future of fisheries.Part I focuses on fisheries. Part II will cover applications in aquaculture.Topics: climate change, fisheries, predictive modeling, AI, ocean data, sustainability, fisheries management, ocean intelligence, climate adaptation, technology in fisheries

What does “more technology” actually mean for fishers?In this Ocean Intelligence reflection episode, Eva sits down with fisherman Joe Letourneau to unpack the realities behind increasing tech use in fisheries. From upfront costs to unclear returns, they discuss whether digital tools are delivering value in practice.The conversation also dives into a key challenge: how fisheries data sharing is communicated, and why current approaches often miss the mark with those on the frontlines.A practical, honest discussion on technology, incentives, and bridging the gap between policy and practice.

In this episode of Ocean Intelligence, we speak with Paul Woods, co-founder and Chief Innovation Officer at Global Fishing Watch, about how technology is transforming our understanding of what happens at sea.While much attention has been given to vessel tracking transparency in fisheries, this conversation goes further. We explore how satellite data, AIS, and AI are used not only to monitor fishing activity, but also to shed light on other ocean uses, including shipping, offshore energy, and seabed mining.The discussion looks at how these tools contribute to more transparent and accountable ocean governance, while also recognising their limitations. What can we realistically detect? Where do gaps remain? And how should this data be used by governments, industry, and civil society?This episode offers a practical look at how monitoring technologies are shaping decision-making across the ocean space, and what that means for the future of seafood and beyond.

In this episode of Ocean Intelligence, Eva van Heukelom (Natural Justice) speak with Jimmy Freese from AI Fish about how electronic monitoring (EM) and artificial intelligence are changing the way fisheries data is collected and verified. From estimating catch weight and size to identifying bycatch and interactions with endangered species, these technologies offer new tools to strengthen fisheries management.At the same time, we explore the practical limitations of these systems—what they can and cannot reliably deliver, and where human oversight remains essential. This conversation brings a grounded perspective to the role of AI in fisheries, moving beyond hype to consider how these tools can realistically support more accountable and effective management.#AI #fisheries #technology #environment #oceans

Electronic monitoring is transforming how fisheries are managed. Cameras installed on fishing vessels, combined with artificial intelligence, are creating unprecedented opportunities to improve transparency, compliance, and fisheries science.In this episode of Ocean Intelligence, a podcast series by Natural Justice, we speak with Josh Wiersma from Integrated Monitoring about the rapid evolution of electronic monitoring (EM) in the seafood sector.We discuss how onboard camera systems work, how AI can analyse fishing activity at scale, and why electronic monitoring is becoming a critical tool for fisheries management, sustainability, and supply chain accountability.Topics covered include:• What electronic monitoring systems are and how they work• The role of AI in analysing fishing activity and catch data• How cameras onboard vessels can support fisheries compliance• Opportunities and challenges in scaling EM programmes globally• The future of technology-driven fisheries managementAs governments, seafood companies, and researchers look for better ways to monitor fishing activity, electronic monitoring is emerging as one of the most powerful tools available.Ocean Intelligence is a podcast series by Natural Justice exploring technology, policy, and innovation shaping the future of fisheries and aquaculture.Subscribe for more conversations with experts working at the intersection of seafood, technology, and sustainability.#Fisheries #ElectronicMonitoring #AI #SustainableSeafood #OceanIntelligence #FisheriesManagement

In this episode, Eva van Heukelom talks to Samantha Robb, a South African lawyer specialising in deep-sea mining, to dive into one of the most pressing questions for our planet’s future: should we start mining the ocean floor before we understand it?We unpack what deep-sea mining actually is, how it’s governed under international law, and why scientists and lawyers alike are warning against rushing into it. The deep ocean, a world we know less about than the surface of the moon, holds both extraordinary life and the metals needed for our clean-energy transition. But can we pursue one without destroying the other?Join us for a conversation that cuts through the complexity and asks what responsible stewardship of the deep sea should look like before it’s too late.Deep sea mining, ocean conservation, environmental law, seabed minerals, International Seabed Authority, marine ecosystems, law of the sea, sustainability, ocean protection, environment, blue economy, deep ocean exploration.
