Our research focuses on the interactions between fish and their environment in the context of aquaculture.
We explore environmental requirements and aquaculture technologies, integrating biotechnologies related to stress and welfare, feed and nutrition, health, reproduction, and early life stages. Our goal is to understand how biotic and abiotic factors affect the biology of farmed fish, aiming to define rearing environments that enhance fish performance and welfare.
Our team has expertise in fish immunology, health, genetics, physiology, nutrition, and aquaculture technology, including recirculating aquaculture systems (RAS). We tackle research problems from various perspectives, with solutions potentially involving studies at the molecular level, through cells and tissues, to observations of living fish. While most of our work is conducted under controlled conditions, we also engage in field studies in collaboration with partners from the fish farming industry.
Our teaching activities focus on aquaculture production and technology, fish nutrition, fish physiology, fish welfare and early life stages of marine fish at Bachelor or Master level as well as professional training. We also teach in aquatic ecology and other subjects.
