摘要： Exopalaemon carinicauda, a eurythermal and euryhaline shrimp, contributes one third of the total biomass production of polyculture ponds in eastern China and is considered as a potential ideal experimental animal for research on crustaceans. We conducted a high-quality chromosome-level genome assembly of E. carinicauda combining PacBio HiFi and Hi-C sequencing data. The total assembly size was 5.86 Gb, with a contig N50 of 235.52 kb and a scaffold N50 of 138.24 Mb. Approximately 95.29% of the assembled sequences were anchored onto 45 pseudochromosomes. BUSCO analysis revealed that 92.89% of 1,013 single-copy genes were highly conserved orthologs. A total of 44, 288 protein-coding genes were predicted, of which 70.53% were functionally annotated. Given its high heterozygosity (2.62%) and large proportion of repeat sequences (71.49%), it is one of the most complex genome assemblies. This chromosome-scale genome will be a valuable resource for future molecular breeding and functional genomics research on E. carinicauda.
