Only about 10% of today’s global aquaculture production use genetically improved stocks. In Europe, some breeding programmes consist of only the basic components of a breeding scheme. Hence, there is large potential to increase efficiency and profit by domestication and genetic improvement of farmed finfish. The main challenge of FISHBOOST is to realise this potential into economic and social acceptable breeding schemes, and advance these for each of the six target species. Acknowledging the different capacities of the species, the aim of FISHBOOST is: To improve the efficiency and profitability of European aquaculture by advancing selective breeding to the next level for each of the six main finfish species through collaborative research with industry. FISHBOOST considers the main components of breeding programmes for Atlantic salmon, common carp, European seabass, gilthead seabream, rainbow trout and turbot. Disease resistance and production efficiency are genetically improved through detailed phenotyping and advanced genomic technologies. The economic impact and producers’ perceptions will be assessed for the recommendations for each of the species. 14 well-recognised RTD participants in Europe on aquaculture breeding will collaborate in a five year comprehensive research project with 7 SMEs, 4 large industries and 1 NGO throughout Europe that are in the lead of the development of their species’ breeding programmes or are vectors between industry and RTD. A mixture of low and high-tech technological advances depending on current capacities of the species will be developed to move each species’ breeding program to the next level. This step-change advance will facilitate balanced and sustainable breeding programmes applying a wide set of traits, breeding tools and technologies. A dissemination program will deliver these results to SMEs and other end-users, thereby advancing existing and stimulating new aquaculture breeding programmes in Europe.
