Pampus argenteus Genome sequencing and assembly

Pampus argenteus is one of the major fishery species in coastal China. P. argenteus has highly specialized morphology, while its declining fishery resource encourages massive research effort on its aquacultural biology. In this study, we reported the first high-quality chromosome-level genome of P. argenteus by integrating Illumina, PacBio HiFi, and Hi-C sequencing techniques. The final size of this genome was 518.06 Mb, with a contig and scaffold N50 of 20.47 and 22.86 Mb, respectively. The sequences were anchored and oriented onto 24 pseudo-chromosomes based on Hi-C data, corresponding to the 24-chromatid karyotype of P. argenteus. Clear co-linearity relationship was observed between the P. argenteus genome with those of its closely related species (Scomber japonicus). 24,696 protein-coding genes were identified from the genome, with 98.9% of complete BUSCOs detected. The genome represents the first case of high-quality chromosome-level genome assembly for P. argenteus, which can provide valuable information to future evolutionary, conservation, and aquacultural research.
