Klargjøring og vurdering av kritiske faktorer for etablering av et avlsprogram for atlantisk kveite

Offentlig prosjektsammendrag

Atlantic halibut (Hippoglossus hippoglossus) is a highly valued seafood, but overfishing has led to stock collapses, making it scarce. While production has recently increased, it remains low due to the lack of breeding programs, which have greatly improved efficiency in other aquaculture species. This project aims to assess the feasibility of a breeding program for halibut by evaluating genetic diversity in broodstock from four companies, defining breeding goals, and establishing trait selection criteria. Aquaculture breeding presents challenges due to high fecundity and communal rearing. To address this, we will evaluate different breeding strategies, including traditional family-based breeding and genetic marker-assisted selection using SNP panels. Additionally, we will conduct association studies to identify genetic links to key production traits. These efforts will help establish an effective breeding program to enhance halibut production efficiency and sustainability.
