Research

Current research topics

My activities deal with the design of sustainable aquaculture systems and environmental assessment of entire aquacultural production systems. Integrated Multi-Trophic Aquaculture (IMTA), based on associating organisms of different trophic levels to increase nutrient-use efficiency, interests me in particular. I observe fishpond systems as well as recirculating aquaculture systems, such as aquaponics or spirulina production.

The systems considered are assessed using Life Cycle Assessment (LCA), N and P budgets, biodiversity indicators and stable isotopes (C and N) to determine relationships among organisms present in the system. To test the sustainable systems designed, I perform experiments in experimental and/or commercial facilities

Current projects

  • SIMTAP: Systèmes Aquaponiques multi-trophiques intégrés autosuffisants pour l’amélioration d’une production alimentaire durable, en condition d’utilisation et de recyclage d’eau saumâtre (2019-2022)
  • AMIMA: Assessment of environmental Monitoring methods for Integrated Management of Aquaculture in open sea (2020-2022)
  • SEPURE: Nouvelles stratégies de construction et de conduite de système de production en étang pour une pisciculture durable (2020-2023)
