The Ramalhete Marine Station (sited in Ria Formosa Natural Park, Faro, Portugal) enables a variety of experiments with larvae and juveniles of several species, including nutrition, behavior, and physiology, including acidification studies. It has 500 m2 of indoor tanks, isolated rooms for studies that require environmental control or behaviour, wet and dry laboratories. A 900 m2 outdoor area is used for larger volume tanks and other needs. The tanks provided have different capacities: 100L (n=24); 500L (n=20); 1000L (n=22); 3000L (3); 9000L (5). All tanks are flow-through supplied with filtered natural sea water. Indoor and outdoor systems of tanks for CO2 experiments simulating oceanic acidification scenarios are available. Tanks and space can be adapted to fulfill specific experimental needs as temperature control, photoperiod, light intensity, or salinity.
