StressChron Framework:

Project code 022
Role Coordinator
Research area Contributing to a more sustainable and animal welfare minded food production
Research topic Improving sustainability and animal welfare in aquaculture and husbandry
Vertebrate Fish
Species Carp (Cyprinus carpio)


The research goal is providing a long-term (2 years) biological validation of cortisol in scales of carp (Cyprinus carpio) as biomarker for chronic stress. This will allow an objective, animal friendly way to evaluate chronic stress and in a broader sense the long term animal welfare on a large scale at the aquaculture farm, at sea, in public aquaria and laboratory fish.
