Background and activities

The PhD position

Gaspard Philis is a PhD candidate at the Department of Biological Sciences Ålesund at NTNU, financed by the NTNU Sustainability program. This PhD project is conducted in collaboration with RISE - The Swedish Research Institute and the Norwegian Veterinary Institute and linked to the NTNU Aquaculture Pilot project supported by NTNU Oceans and NTNU Sustainability

Furthermore, Gaspard Philis participate in the development of the ISO/NP 22948 Carbon Footprint for Seafood - Product Category Rules (CFP-PCR) and the report "Assessment of the impacts of land-based activities on marine and coastal resources and environment" lead by the UNEP International Resource Panel

Area of research

This PhD project focuses on the topic of aquaculture sustainability and more specifically on the quantitative measurements of environmental impacts generated by the Norwegian aquaculture industry. Our research effort concentrate on improving the comprehensivness of current Life Cycle Assessments (LCA) measuring the environmental impact of Norwegian salmon production. To work towards this objective, three main area of research have been identified:

  • Quantifying the environmental impacts associated with biological lice treatments in the Norwegian aquaculture (cradle-to-grave).
  • Quantifying the environmental impacts associated with mechanical and chemical lice treatments, including impacts derived from increased mortality (cradle-to-grave).
  • Comparing LCA results of salmon lice treatments using an innovative stochiastic multicriteria acceptability analysis, with specific weighting regime.

Previous work

  • "Comparative Material and Substance Flow Analysis (MFA/SFA) of two aquafeed protein rich ingredients: Brazilian Soy Protein Concentrate (SPC) and Norwegian Seaweed Protein Concentrate (SWPC)". This study was part of the environmental assessment conducted in the PROMAC research project.
  • Participation to an MFA/SFA study tracking plastics (Nylon, PE, PP) embedded in fishing gears lost and discarded by the Norwegian fishing fleet in the ocean (study conducted under the Circular Ocean Project).
