Integrated environmental analysis for a sustainable aquaculture development: Scenarios of marine fish farming in the Mayotte lagoon.
Marine aquaculture has a high growth potential, useful for meeting current and future populations’ food needs. Aquaculture activity, including the stage of production and those upstream and downstream the value chain, however, is responsible for potential environmental impacts on local (e.g. benthic...

Marine aquaculture has a high growth potential, useful for meeting current and future populations’ food needs. Aquaculture activity, including the stage of production and those upstream and downstream the value chain, however, is responsible for potential environmental impacts on local (e.g. benthic impact) or global (e.g. impact on climate change) ecosystems. To minimize these impacts, it is necessary to develop environmental analysis methods with a holistic approach. The general objective of this thesis was to design a method to assess environmental impacts at different spatial scales (local, regional, global) by combining modeling tools at several organizational scales (individual, farm, sector) and scenario analysis. This method was tested on a case study of red drum (Sciaenops ocellatus) farming in Mayotte lagoon. Three farm scenarios were built based on field surveys.
