Abstract
The greater amberjack (Seriola dumerili) is a globally important pelagic fish valued for its rapid growth, superior flesh quality, and high aquaculture potential. Here, we report the first telomere-to-telomere (T2T) chromosome-level genome assemblies for male and female S. dumerili generated through an integrated sequencing strategy combining Pacific Biosciences High-Fidelity (PacBio HiFi) long reads, MGI (MGI Technology, Inc.) short reads, and Hi-C (chromosome conformation capture) data.The assemblies spanned 685 Mb (female) and 683 Mb (male), each anchored to 24 chromosomes and exhibiting near-complete continuity and accuracy. Both genomes achieved exceptional completeness, with over 99.3% of the BUSCO genes identified, and contained 22,352 and 22,325 annotated protein-coding genes, respectively. The availability of these T2T genomes provides a comprehensive resource for investigating sex-specific genomic features, evolutionary adaptation, and functional mechanisms underlying growth and disease resistance, thereby advancing molecular breeding and sustainable aquaculture of the greater amberjack.
