Abstract Maintaining genetic diversity in cultured shellfish can be challenging due to high variance in individual reproductive success, founder effects, and rapid genetic drift, but is important to retain adaptive potential and avoid inbreeding depression. To support broodstock management and selective breeding in cultured Pacific oysters (Crassostrea (Magallana) gigas), we developed an amplicon panel targeting 592 genomic regions and SNP variants with an average of 50 amplicons per chromosome.

Abstract Maintaining genetic diversity in cultured shellfish can be challenging due to high variance in individual reproductive output, founder effects, and rapid genetic drift. However, it is important to consider for retaining adaptive potential and avoiding inbreeding depression, particularly in species with high mutational load.
