A Systematic Review and Meta-Analysis of Basal and Post-Stress Circulating Cortisol Concentration in an Important Marine Aquaculture Fish Species, European Sea Bass, Dicentrarchus labrax
Summary
This meta-analysis found that European sea bass have naturally higher cortisol levels than most studied fish species, with significant variation across studies. All forms of stress consistently elevated cortisol further, highlighting the importance of standardizing stress assessments in aquaculture research.
Cortisol levels in E. sea bass are higher than most studied fish species and display large heterogeneity. Application of stress led to elevated cortisol levels in all studies examined. In all cases, sources of between-studies heterogeneity were identified.

The Importance of Monitoring Cortisol in the Agri-Food Sector—A Systematic Review
This systematic review found that cortisol monitoring in livestock and aquaculture is a valuable indicator of animal welfare, production quality, and food safety. Elevated cortisol from chronic stress can reduce meat and fish quality, making stress hormone tracking an important tool across the food supply chain.
Effect of Handling Stress on Primary and Secondary Stress Responses of the Catfish, Clarias batrachus
Researchers found that the catfish Clarias batrachus showed no statistically significant changes in cortisol, glucose, or osmolality levels across non-anaesthetized, anaesthetized, and stressed conditions, indicating it is a hardy species that tolerates routine laboratory handling without measurable stress responses.

Researchers evaluated how functional feed additives affected stress response and gill antioxidant capacity in a selectively bred high-growth European sea bass genotype, finding that dietary supplements could help reinforce oxidative stress tolerance during hydrogen peroxide treatment.
Physiological Stress and Tissue Damage Response of Ctenopharyngodon idella to Artificial and Automated Injection
Researchers evaluated physiological stress and tissue damage responses of grass carp Ctenopharyngodon idella to artificial versus automated injection methods, finding that the automated injection group exhibited faster epithelial regeneration alongside similar immune and cortisol responses.
A multiple biomarker approach to understand the effects of microplastics on the health status of European seabass farmed in earthen ponds on the NE Atlantic coast
Researchers studied European seabass farmed in earthen ponds to understand how microplastic exposure relates to fish health. Using multiple biomarkers including blood chemistry, immune response, and tissue analysis, they found measurable biological changes linked to microplastic levels in the fish. The findings raise concerns about seafood quality from aquaculture systems that are exposed to environmental microplastic contamination.
