Development and validation of a combined species SNP array for the European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata)

Abstract: SNP arrays are powerful tools for high-resolution studies of the genetic basis of complex traits, facilitating both population genomic and selective breeding research. The European seabass (Dicentrarchus labrax) and the gilthead seabream (Sparus aurata) are the two most important fish species for Mediterranean aquaculture. While selective breeding programmes increasingly underpin stocky supply for this industry, genomic selection is not yet widespread. Genomic selection has major potential to expedite genetic … Show more

“…Reduced representation sequencing can be a valuable tool for selective breeding practices in emerging aquaculture species, such as Arctic charr [14]. Genomic information is useful for important aspects of fish breeding that include, but are not limited to estimating relationships between individuals, assessing genetic diversity in populations and even investigating the genetic basis of phenotypic variation [41]. However, the cost of genotyping is a limiting factor for the sustainability of breeding programs.…”

“…Tissues samples were sent to Identigen for DNA extraction and genotyping (Identigen Ltd, Dublin, Ireland). The combined-species 60K SNP array for the European seabass and the gilthead seabream (the MedFish SNP chip), which was developed in a collaboration between the MEDAID 1 and PERFORMFISH 2 consortia was utilized ( Penaloza et al, 2020 ). A total of 22,246 SNPs were available on European Seabass after setting a quality threshold at 93%.…”
