The Aquatics Facility at uOttawa comprises holding and experimental space for a variety of freshwater and marine fish species (including goldfish, rainbow trout and other temperature-water species, ghost knifefish, zebrafish, lungfish and the marine toadfish), as well as amphibians. Freshwater fish are held under appropriate photoperiod in recirculating systems supplied with flowing, temperature-controlled dechloraminated city of Ottawa tap water; flow-through capacity is also present for toxicology studies. In addition, the facility provides the capacity for control of water temperature and ionic strength for experimental purposes. The Aquatics Facility is staffed by a full-time, dedicated animal care technician. In addition, a second full-time technician is dedicated to the zebrafish room.
