Laboratory for Physiology and Genetics of Aquatic Organisms

Aquatic Organisms

The Laboratory for Physiology and Genetics of Aquatic Organisms houses numerous fish and amphibian species, including:

Zebrafish (Danio rerio)

The zebrafish holding systems are comprised of 20 modular racks supporting approximately 1,000 tanks of various capacities. The facility maintains both wild-type and transgenic zebrafish at the standard temperature of 28.5°C. In addition to the main zebrafish facility, there is also an isolated quarantine room fitted to accommodate experiments requiring chemical exposures. The zebrafish facility constitutes one of the largest for this species in Canada.

Brown ghost knifefish (Apteronotus leptorhynchus)

An isolated room is maintained for neurophysiological and behavioural work on the weakly electric knifefish.

Goldfish (Carassius auratus)

There are 40 tanks for housing goldfish, which require their own temperature control for specific experiments (between 12°C and 24°C).

Gulf toadfish (Opsanus beta)

A specially built marine facility is used to house warm seawater species, such as the Gulf toadfish. This unique installation provides temperature controlled recirculating seawater.

Salmonids (e.g. trout) and other large teleost fish

Three rooms house a common holding system consisting of 26 tanks of varying capacities. The facility can house trout or similar sized species (including American eels, catfish, etc). Temperatures can be maintained within these systems between 4°C and 22°C, depending upon the required experimental design.

Amphibian species

Temperature-controlled and humidified rooms are dedicated for the holding and manipulation of western clawed frogs (Xenopus tropicalis) and leopard frogs (Lithobates pipiens).
