International audience. the bay scallop, Argopecten irradians, is a species of major commercial, cultural, and ecologicalimportance. It is endemic to the eastern coast of the United States, but has also been introducedto China, where it supports a significant aquaculture industry. Here, we provide an annotatedchromosome-level reference genome assembly for the bay scallop, assembled using PacBio andHi-C data. The total genome size is 845.9 Mb, distributed over 1,503 scaffolds with a scaffold N50 of44.3 Mb. The majority (92.9%) of the assembled genome is contained within the 16 largest scaffolds,corresponding to the 16 chromosomes confirmed by Hi-C analysis. The assembly also includes thecomplete mitochondrial genome. Approximately 36.2% of the genome consists of repetitive elements.The BUSCO analysis showed a completeness of 96.2%. We identified 33,772 protein-coding genes. Thisgenome assembly will be a valuable resource for future research on evolutionary dynamics, adaptivemechanisms, and will support genome-assisted breeding, contributing to the conservation andmanagement of this iconic species in the face of environmental and pathogenic challenges
