The identification of the gene responsible for IPN resistance in salmon enables a great accuracy in the selection of broodstock, ensuring the offspring to be resistant to IPN.

This gene is found to have two mutations that prevent the IPN virus from infecting salmon cells.

On 10-12 June 2014 the second international conference on integrated salmon biology was held in Vancouver, Canada.

This conference marked the completion of the salmon genome project. This work started in 2010 as a collaborative project between academia, industry and government funding agencies in Chile, Canada and Norway.

It is expected that the reference genome for salmon will provide important information of great benefit to the salmon farming in the future.

One example of the use of genetic information that has already brought significant improvements for farmed fish are genetic markers for resistance to infectious pancreatic necrosis (IPN) in salmon.

At the conference, seniorscientist Thomas Moen from AquaGen presentedthe work doneto discover the actual gene and reveal the mechanism behind IPN resistance in salmon.

IPN is a very common viral disease, and is one that has been responsible for significant losses in salmon farming.

The disease has proven to be very difficult to control by vaccination or other preventive or loss-reduction measures adopted over the years.

By the late 90s it had been documented that there was a significant genetic variation in salmon susceptibility to IPN.
