The Team
Fisheries experts, data scientists, legal advisors, and engineers working to make the global fishing fleet visible and accountable.
Roberto Mielgo Bregazzi
Roberto Mielgo Bregazzi is an independent international fisheries consultant, data analyst, and applied AI specialist, currently leading concept development for the Kanikosen Platform Project. He was the founder and technology development director of the FishSpektrum Project — a predecessor registry of global fishing vessel tracking using AIS, VMS, and VDS data. He served on the European Fisheries Control Agency (EFCA) Fisheries Compliance Experts’ List and attended multiple sessions of the European Parliament’s PECH Committee as an observer/consultant on behalf of WWF, Greenpeace, and the Pew Charitable Trusts. He participated as a consultant at the 15th, 16th, 17th, 20th, and 21st Ordinary and Special Meetings of the International Commission for the Conservation of Atlantic Tuna (ICCAT) held across Dubrovnik, Antalya, Marrakesh, Paris, Istanbul, and Agadir (2006–2012), as well as at ICCAT-SCRS Bluefin Tuna Stock Assessment Meetings in Madrid. His recent consultancy work includes fishing fleet data acquisition and analysis for ODI Global in London on IUU fishing in West Africa and on Chinese distant-water fleets, the latter commissioned under the UNDP Ocean Innovation Challenge; data analysis for the Outlaw Ocean Project (USA) on Chinese fleet activities; and the transfer and updating of the Krakken Unique Vessel Identifier database for Vulcan Technologies / Allen AI – Skylight in Seattle. His publications include a coauthored 2016 ICCAT scientific paper on Atlantic Bluefin Tuna weight frequencies (SCRS/2016/142) and a 2014 ICCAT SCRS report on the weight/size structure of Atlantic Bluefin Tuna across the Mediterranean and Northeast Atlantic, among others.
Daniel Rolleri
Daniel Rolleri is cofounder of Kanikosen. He is also the director of Asociación Ambiente Europeo, a leading Spanish organization on marine debris that fosters ocean literacy through communication, education, and citizen science. Over more than fifteen years at the helm of the organization, he has led in Spain the International Coastal Cleanup project of Ocean Conservancy — the world’s largest citizen science initiative, with an annual participation of over three-quarters of a million people — and has driven SeaLabs, a project that turns sailors into active collaborators in ocean research, recognized with the Ocean Tribute Award 2025 granted by the Prince Albert II of Monaco Foundation. He is also a board member of the International Institute of Law and the Environment (IIDMA), a member of Ocean Conservancy’s ICC Global Advisory Council, and a co-founder of the Marine Litter Spanish Association (AEBAM). Previously, he worked for MarViva Foundation, a marine conservation organization with a strong presence in Costa Rica, Panama, and Colombia, where he met and collaborated with Roberto Mielgo and Miren Gutierrez. He holds degrees in Law and Applied Linguistics and has extensive organisational and management experience in the public and private sectors, working on projects relating to the environment, education, culture, and politics.
