摘要： Hemibagrus guttatus, also named as spotted longbarbel catfish, is an economical fish in China. However, their gender cannot be easily distinguished from their appearance, which largely impedes their artificial breeding. Therefore, we provided two gap-free chromosome-level genomes of male and female spotted longbarbel catfish by combining wtdbg2, LR_Gapcloser and TGS-GapCloser assembly approaches with Hi-C data and accurate Pacbio HiFi long-reads. We assembled 30 chromosomes without any gap. Their genome sizes are approximately 749.1 Mb and 747.8 Mb of male and female individuals. The completeness results of BUSCO evaluation show about 94.2% and 95.0%, representing a high-level of completeness of both genomes. We also obtained 35,277 and 34,571 protein-coding gene sets from male and female individuals. Both available gap-free chromosome-level genomes of H. guttatus will provide excellent references for resequencing of male and female individuals to identify accurate markers for distinguishing gender of this fish.
