Freshwater Fish-hatchery

INN Centre of Bioeconomy | Inland Norway University of Applied Sciences

The test facility consists of approx. 70 cylinders of 20 liters and 4 x 1 m² vessels. Attached to the waterway are heat flasks (a total of 30 kWh) which allow the manipulation of temperature in 3 gradients. In addition, there are possibilities for manipulating light with individual lighting in each cylinder and manipulating water flow. In the same building there are also 6 x 4 m² tubs that are available. The test facility is connected to a 24-hour continuous guard.

A typical experiment will involve taking disinfecting roe (buffodin) from different populations to the plant and fertilizing them. Specimens of roe are submitted for screening of pathogens and diseases at the Veterinary Institute. If there is any positive samples, that cannot be treated, the infected populations are not included in the experiments. Incubation, starting feeding and further feeding is then then carried out within the walls of the test station. At the end of the trial, all test fish will be euthanized. No experiments involving the addition of chemical substances in the treatment water (eg. tox tests) are carried out, nor are tests that entail bringing other than gametes (milk and eggs) from wild fish into the test rooms.
