19 Feb A study by CSIC7 aims to understand stress in aquaculture fish to improve their welfare.

A study by CSIC7, published in a book by the Dávalos-Fletcher Foundation, analyzes stress in aquaculture fish such as gilthead seabream, European seabass, and meagre, species of great economic interest. In a context where consumers increasingly value animal welfare in the products they consume, this research seeks to improve fish conditions in aquaculture farms through a scientific and practical approach.

The book, titled New Stress Markers in Fish of High Interest in Aquaculture in the Valencian Community, combines a detailed analysis of aquaculture in the region with findings on fish stress. It also studies species with growing market demand, such as the greater amberjack, whose popularity has increased in recent years. The research proposes non-invasive methods to assess stress, analyzing substances like cortisol from scale and fin samples.

This work has been driven by the “Fish NeuroBehaviour Lab” at IATS-CSIC, in collaboration with the company AVRAMAR and supported by the Dávalos-Fletcher Foundation. The study has received funding from the European Union “NextGenerationEU” (PRTR-C17.11) and the Generalitat Valenciana (THINKINAZUL/ 2021/025).
