LABORATORY
Applied Hydrobiology

The Research Activity

of the Laboratory of Applied Hydrobiology focuses on the study of aquatic organisms, in terms of husbandry, ethology, physiology and ecology.

  • Effect of rearing factors such as temperature, feeding regime, fish density, photoperiod, tank coloration, light density and coloration etc on aquatic organisms. Effects of experimental conditions are evaluated with hematological parameters (hematocrit, cortisol, glucose, electrolytes, enzymatic activity, dissolved gasses etc.).
  • Fish behavior is studied with a view to understand ethological and dietary demands, in relation with diets enriched with various nutrients (e.g. fatty acids, amino acids, vitamins etc), targeting towards improving fish welfare, growth rates and carcass quality. The aforementioned research is always conducted considering the protection of aquatic environment.
  • Enhancement of fish quantitative and qualitative traits during intensive production as well as the improvement of the production systems.
  • Fish traceability and authenticity trials, in order to define local fish populations with the use of modern molecular biology techniques.
  • Sustainable management of the marine environment.
