Supporting Data for: Product Environmental Footprint (PEF) of gilthead seabream (Sparus aurata) juveniles fed side-streams from farmed blue mussel

</p>The dataset is used as a foundation for the scientific article Product Environmental Footprint (PEF) of gilthead seabream (Sparus aurata) juveniles fed side-streams from farmed blue mussel. This study analysed the environmental footprints of rearing juvenile gilthead seabream using Life Cycle Assessment (LCA) principles aligned with the Product Environmental Footprint (PEF) method. Data were collected from a research facility where fish juveniles were fed diets with fishmeal partially or fully substituted at 100%, 50%, or 0%, with blue mussel (Mytilus galloprovincialis) meal. The results showed that the use of electricity and the feed were the largest contributors to most impact categories. Electricity use was primarily driven by the indoor flow-through facility's high-water renewal and lighting requirements. The sensitivity analyses showed a high uncertainty related to impacts from the blue mussel production. This dataset is connected to the interdisciplinary research project SECURE (Novel Marine Resources for Food Security and Food Safety) which investigate the potential of low-trophic marine species. The overall goal of the project is to develop knowledge that enables sustainable food security. More information is available through https://en.uit.no/project/secure.</p>
