India’s coastal waters hold immense promise—and growing peril. In this episode of the Think Wildlife Podcast, host Anish Banerjee speaks with Oishinee Chakraborty from the Kuddle Life Foundation, a young organization redefining marine conservation in Pondicherry through science, community collaboration, and artificial reefs.
Oishinee introduces listeners to the Foundation’s origins—founded in 2020 by Punit Dhandhania and Hans Dhandhania, who transformed a small circle of ocean enthusiasts into a leading grassroots force for marine ecology and biodiversity conservation. With limited institutions working on ocean protection in southern India, Kuddle Life fills a critical gap by creating local, science-driven projects that link marine ecosystems, coastal livelihoods, and sustainable development.
At the heart of their work lies the artificial reef program—a groundbreaking effort to restore degraded marine ecosystems and revive marine biodiversity. Oishinee explains that space is the ocean’s most limiting factor, and artificial reefs—built using eco-friendly materials like concrete and steel—mimic the natural hard surfaces that corals, sponges, and fish larvae need to attach, grow, and form thriving underwater communities. These structures replicate some functions of natural coral reefs, acting as catalysts for marine biodiversity management and ecosystem recovery.
The process of building an artificial reef begins with community engagement. Fisherfolk are invited to share local ecological knowledge and help identify suitable sites for reef deployment. Scientists then assess seabed topography, water quality, and existing biodiversity before designing reef modules—each over 500 kg and a meter tall. Local divers and fishermen help deploy the structures less than five kilometers offshore, making the effort both participatory and empowering.
Monitoring continues for years, as reefs mature and attract a diversity of marine wildlife. In Pondicherry, Kuddle Life has recorded remarkable results: a 20% rise in dissolved oxygen, increased chlorophyll levels, and nearly a fourfold growth in fish abundance. For local fishers, incomes have doubled—from ₹5,000 to ₹10,000 per day—while fuel costs have halved because fishing now occurs closer to shore. These outcomes highlight how marine biodiversity conservation can drive both ecological and economic resilience.
Globally, artificial reefs have become vital tools for restoring marine ecosystems damaged by climate change, overfishing, and pollution. Yet, as Oishinee reminds us, nothing can replace natural coral reefs. Artificial structures can only supplement lost habitat, not substitute for nature’s complexity. Still, by reviving degraded areas and promoting sustainable fishing, these reefs help maintain ocean productivity in a warming world.
Beyond reef restoration, the Kuddle Life Foundation runs educational and research programs across India. Through marine litter surveys, bycatch reduction initiatives, dive training, and youth internships, the foundation is building a generation of ocean stewards. Its unique for-profit dive center reinvests earnings into conservation, while volunteers support marine ecology projects both underwater and onshore—from data analysis to biodiversity monitoring.
Oishinee also discusses the challenges of sustaining NGO work in India—funding barriers, bureaucratic delays, and the slow pace of conservation impact. Yet, she finds hope in the growing public interest in marine biodiversity, particularly when students and non-biologists approach her asking how they can help. That curiosity, she believes, is the first step toward lasting ocean change.
This episode reveals how grassroots innovation, science, and compassion are reshaping marine biodiversity hotspots along India’s coast—proving that ocean recovery begins not just beneath the waves, but within communities themselves.
