Luke maintains and develops breeding programmes for farmed rainbow trout and European whitefish.

Selective breeding of farmed fish improves the profitability of the aquaculture business and the quality of food available for consumers. The applied selective breeding methods improve not only the production traits of fish, but also their quality and health. On the whole, selection is aimed at establishing food production that is increasingly ecological, ethical and economical.

Higher quality fish for consumers from JALO breeding programme

The JALO selection programmes for rainbow trout (established in 1992) and European whitefish (established in 2002) have developed into a highly advanced and internationally competitive programmes. The programme deploys the latest animal breeding methods (for example, programmes are a result of long-standing collaboration between fish farmers, processing industry and animal breeders.

Continuous research and development work is practiced to generate more effective breeding programmes fulfilling customer needs.  Under the JALO programme, a new selection index for rainbow trout is being developed, enabling the improvement of fish characteristics that have a strong economic impact on the profitability of the companies across the whole value chain. To enhance aquaculture practices of our international partners, co-operative projects are established to distribute improved fish material and to exchange knowledge on measurement technology, construction of fish breeding programmes and on animal breeding methods.

Protection of genetically improved fish material

JALO breeding programme aims at increasing the productivity of its clients, but simultaneously at protecting its genetically unique fish material from being misused by other broodstock owners.

To provide fish for farmers and multipliers, the breeding programme utilises a new method to produce large numbers of eggs and fingerlings with a very narrow genetic background which prevents the establishment of new broodstock populations. Simultaneously, the method results in more homogeneous stock of production fish, and enables the customisation of fish batches that are based on selection criteria that differ slightly from those of the underlying programme. The method has been patented.
