Non-invasive biomakers of fish welfare
Non-invasive biomakers of fish welfare
NIBIFish-UB (“Non-Invasive Biomarkers in Fish”) is the UB’s research group within the Energy and Metabolism Intermediary in Fish group. Our research assesses the welfare and health of fish by using non-invasive biomarkers of skin mucus. We are also experts in the general fish metabolism according to their nutrition, environmental conditions and the characteristics of each species. This group belongs to the Department of Cell Biology, Physiology and Immunology of the University of Barcelona (UB), where we have the adequate facilities for the study of fish biology.
FOR WHOM WE WORK
The different members of the group have more than 15 years of experience in the Aquaculture, Farming and Veterinary sectors. We are experts on both marine species (sea bream, sea bass, sole, meagre, tuna) and freshwater species (trout, salmon, sturgeon). Our partners and customers include aquaculture farms, feed additive companies, feed manufacturers and veterinary products companies.
- Monitoring in situ of animal welfare and correlation with productivity.
- Determination of non-invasive biomarkers from skin mucus to study physiological state.
- Obtaining new antimicrobial products derived from the skin mucus.
- Integral design for the increase of the aquaculture productivity: feeding management, physical activity and the culture conditions.
- Non-invasive studies of the functional diets via skin mucus antibacterial capacity
