Only 15% of the world aquaculture production utilizes genetically improved stock. As result producers of many species around the globe are facing constraints related to stock performance that could partially and totally be resolved through the application of selective breeding techniques

Genomar has a unique combination of resources and track records in managing breeding programs for Atlantic salmon and Nile tilapia which can be deployed for other species.

•    Improve growth rates
•    Reduce production cost
•    Improve disease resistance

breeding program


•    Characteristics of GST breeding Program
•    Wide genetic diversity and world-class management
•    Pedigree data and DNA-assisted parental selection.
•    Combined Selection.
We use a mixed of individual and family selection to maximize genetic gain.

•    Breeding Goals  (read more) We believe strongly on the role of animal breeding to support the efficiency and sustainability of the industry. Therefore we apply a balanced approach between production and functional traits to deliver our customer with a tilapia stocks that perform well in a variety of conditions.

•    Harvest weight
•    Stress tolerance
•    Fillet yield
•    From 2015:
•    Streptococcus agalactiae
•    Flexibacter columnaris
•    Robustness
•    Others
•    Control of inbreeding
To have a sustainable long term breeding program it is important to control the rate of inbreeding. Too rapid increase of inbreeding level can result in increased disease susceptibility, higher frequency of malformations, loss of performance and ultimately loss of potential for further genetic improvement.

Innovation: Genomic Selection
In January 2015, Genomar AS and the Center for Integrative Genetics (CIGENE) signed a collaboration agreement for the development and application of a high density SNP array for Nile tilapia.

High-density SNP arrays are utilized in human medicine research and terrestrial animal breeding to study the genetic basis of many conditions, particularly metabolic and infectious diseases

These great tools will be utilized to genotype GST tilapia for thousands of markers located across the genome. The analysis of variation between individuals and populations for those markers will allow us to pinpoint genes or areas of the genome with ´effect´ on tilapia diseases and other traits of interest.
Markers correlated with traits of interest will then be used, together with conventional breeding values, to evaluate selection candidates in the breeding program.
We are continuously looking to improve our breeding program by including new technologies and traits.
