Hatchery Room


Eggs of Atlantic cod (Gadus morhua), Atlantic hailbut (Hippoglossus hippoglossus), and yellow flounder (Limanda ferruginea) have been successfully incubated in the hatchery room at the Joe Brown Aquatic Research Building.

There are twenty-three 330 litre incubators and thirty-four 50 litre incubators available to accommodate researchers specific needs. The current set up of sixteen 330 litre and twenty-eight 50 litre incubators was recently used by the Atlantic Cod Genomics and Broodstock Development program to raise 56 Atlantic cod families.

Each incubator is equipped with its own water inlet and aeration line and fitted with banjo filters to prevent the escape of eggs and larvae. Incubators can be adapted for both pelagic and demersal eggs by changing the configuration of the incoming water.

An adjacent preparation room is available with laboratory equipment and supplies including fume hood, microscope and dry bench. An ozone gas generator is available to use for egg disinfection prior to incubation.

In addition, an overhead lighting system with variable intensity and emergency bottled oxygen supply is available.
