Frédéric Le Manach

Frédéric Le Manach — BLOOMIt is on the coast of Brittany that Frédéric Le Manach discovered the marine fauna and flora, their exploitation (be it sustainable or not), and the impacts of human activities on the Big Blue. When not in Brittany during holidays it was with Cousteau’s TV team that he went through apprenticeship in the Parisian suburbs.

Frédéric chose to maritimize his career during his Bachelor at the University of Paris. After spending a year in Marseille learning about marine ecology and biology, he then integrated the European Masters in water and coastal management in England (Plymouth) and Spain (Cádiz). It is during these two years that he discovered the importance of the fishing industry, but also its problems and injustices. For his internship, he worked on reconstructing catch data in Madagascar and established himself at the University of British Columbia in Vancouver, Canada. This internship offered him many opportunities, including a contract with the World Bank to strengthen the knowledge on Madagascar’s small-scale fishers. There, he discovered the ravages that a lack of political will and means may cause, particularly with regards to the illegal and very dangerous trade in holothurians (sea cucumbers) and shark fins. This short period as a consultant for a UN agency teached him something else, though: this is not what he wants to do with his life…

Back in Vancouver at the Sea Around Us project, Pr. Daniel Pauly offered him to do a PhD on the topic of his choice. Increasingly obsessed with the gap between industrial and artisanal fisheries, it is quite naturally that Frédéric decidee to look at a crucial yet poorly studied subject: the fisheries access agreements established by the European Commissionon behalf of its industrial fleets — with developing countries, particularly in West Africa, the Indian Ocean and increasingly in the Pacific Ocean. To deepen his knowledge, he partnered with the French Research Institute for Development in Sète, France, where many experts on tuna and African fisheries worked. There Pr. Philippe Cury co-supervised his thesis.

The results of Frédéric’s thesis eventually showed how fisheries agreements, for a modest “financial compensation” (largely paid for by European taxpayers), enabled European companies to exploit the rich waters of many tropical countries: shrimp, lobster, octopus and sardinella in the past; mainly tuna nowadays. Such conclusions provoked the ire of French industrials, but one of their representatives eventually publicly acknowledged that access rights paid by industrials to “partner” countries were low compared to their turnover. The cost of these access rights will be increased (from €35 per tonne of tuna caught — and reported — to €55) shortly afterward when certain agreements were renewed in the Indian Ocean.

Frédéric joined BLOOM in January 2015 to lead the scientific program carried out by a small team of young and eager researchers. He is currently leading projects on various topics that aim to produce more ecologically and socially viable fisheries models. His analyses focus on the state of European fish stocks, the practices of various industrial sectors such as reduction fisheries (that produce fishmeal used by the aquaculture and cattle industries) and tropical tuna fisheries. He also works on the impact of public subsidies and on the responsible consumption of fish. He also always takes pleasure in teaching and participating to festivals, round tables etc.
