The laboratory possesses all the necessary equipment (glassware, reagents, spectrophotometers, pipettes and commercial kits) for the determination of the physicochemical characteristics of both freshwater and saltwater (Dissolved Oxygen, carbon dioxide, alkalinity, ammonia, nitrite, nitrate, chloride ions, total phosphorus, BOD, COD, pH etc.)
The laboratory provides all the appropriate equipment for biochemical analysis (glassware, lyophilizer, HPLC, GC, GC-MS, gas analyzer, blood electrolytes, image analyzer, centrifuges etc) in aquatic organisms. Among other methods, a plethora of hematological parameters can be quantified (triglycerides, cholesterol, total fat, albumin, glucose, cortisol, osmolarity, hematocrit, red and white blood cells, hemoglobin, blood gases, blood pH, blood electrolytes etc.), carcass composition (fat, protein, moisture, ash), total fats, glycogen, ascorbic acid, moisture and other hepatic indices, digestive enzymes etc.
Stress level determination (acute and chronic) is vital for aquaculture, as stress intensity may hinder fish health and welfare. Its effects have financial impact on the farm, as well as on consumers. Stress determination may be accurately achieved via the determination of the concentrations of fish brain neurotransmitters. In the Laboratory of Applied Hydrobiology, liquid chromatography techniques (HPLC/ECD) are employed to determine the concentrations of serotonin (5-HT), its metabolite 5-HIAA, dopamine (DA) and its metabolites DOPAC and HVA, as well as noradrenaline (NA). 5-HIAA/5-HT and DOPAC/DA ratios are used to determine serotoninergic and dopaminergic activities respectively.
Finally, the lab conducts determination of Paralytic Shellfish Poisoning (PSP) toxins in mollusks by application of a HPLC
