Mathieu Colléter is a fisheries scientist whose research focuses on ecosystem modelling and trophic networks. He is currently a Master’s candidate in Advanced Global Studies, specialized in Environmental Policy, at the Parisian School of International Affairs (SciencesPo Paris). At Nereus, he worked on the production of biomass estimates for the 180,000 ½ degree Sea Around Us cells covering all oceans, from 1950 to 2010, using ecosystem modelling (EcoTroph) and the Sea Around Us’ new spatialized catches. This will be used to model future changes in global biomass and fisheries catch under climate change scenarios.

Biomass is the mass of organisms in an ecosystem or community; it is thought of in terms of energy for the next trophic level – the higher chain in the food web. For example, the biomass of plankton, which may be eaten by herring, which may be eaten by tuna.
Nereus Fellow at UBC Mathieu Colléter participated in the Day of the Thousandth Fisheries Scientist conference, which took place at Agrocampus Ouest in Rennes, France, on September 16.
