The genome of Trichiurus japonicus, commonly known as the Japanese hairtail or cutlassfish, is characterized by its chromosomal organization at the genomic level. This species possesses a diploid chromosome number of 24. Our project also encompasses sequenced transcriptome data, Hi-C (High-throughput Chromosome Conformation Capture) data, and various resequencing data from hairtail species (Trichiurus spp.).
