Experimental Aquaria

Experimental aquaria are essential facilities at PiE-UPV/EHU where a wide range of experiment can be performed with the highest quality required. A plethora of experiments with marine algae, invertebrates and vertebrates can be carried out with highest quality standards.

PiE-UPV/EHU, as partner of EMBRC fulfills the compromise with the ethics and animal healthcare in experimentation regulations.

The building due to its location in the beach has a great opportunity for Sea water supply. Naturally filtered good quality water is obtained from two wells in the Bay of Plentzia.

General characteristics

  • Modular facilities. It allows a perfect design and the development of any experiment and especially useful in toxicological experimentation.
  • High quality seawater continuous supply (up to 300000 L/day) and air supply.
  • Metal free
  • Photoperiod and temperature are independently regulated 
  • Equipped with sea water quality and control:
    • Marine water temperature controler- titanium plate interchanger. It allows the regulation of temperature in flow-through systems (12 m3/h; 14-22 ºC).
    • Data logger for continuous recording of the water quality (pH, conductivity, salinity, oxygen, turbidity, chlorophyll levels)
  • Equipped with its own depuration plant organized in three depurations lines (organic material, hydrocarbons, metals). It allows experimenting with a huge range of contaminants without harming the local depuration plant.
  • In addition, specific filtration units could be installed for specific experiments if it is required.

Examples of type of experiments conducted in PiE-UPV/EHU

  • Toxicological and growth experiments have been performed with marine mollucs such as periwinkles, oysters and mussels.
  • Toxicological experiments have been performed with sole, Solea sp., exposed to model contaminants in sediments and waterborne.
  • Sea bass was exposed to mixtures of emergent contaminants in open flow system using passive dosers in order to investigate changes at chemical, metabolomical and bio/histochemical levels in the sea bass.
  • Experiments carried out to investigate changes in the behavior patterns of sea bass fed Hg contaminated food, using under-water camera records to analyse the entropy of fish movement.
  • Sea urchin is used as model experimental species for biomedical (e.g., membrane lipids of sea urchin embryos as models for cancer research), as well as for toxicological assays.
