Everyday items such as cell phones and solar panels contain non-renewable resources (metals or rare-earth minerals) that need to be extracted responsibly. ILEE prospects and characterizes these geological resources (petrography, mineralogy and geochemistry of supergeneous ores) and integrates human use over the centuries, to improve their sustainable management.

Temperate species (Eurasian perch, zander and trout) and tropical species (striped catfish, African catfish and tilapia) are studied. Emphasis is placed on the application of immune stimulation techniques to find alternatives to the use of antibiotics and chemicals, on the replacement of fishmeal and fish oil with substances of plant origin, and on the improvement of husbandry to promote fish welfare.
