Channa argus Genome sequencing. Channa argus

The northern snakehead (Channa argus) exhibits male heterogamety (XY/XX), as well as an obvious sexually dimorphic growth rate. Within this species, males generally grow more quickly than females. Breeding all-male (XY) populations is preferred for large-scale fish culture. In this study, Hi-C and Nanopore sequencing methods were utilized to produce a chromosome-level genome for an albino XY C. argus var. The size of genome assembly was 0.66 GB, the contig N50 length was 13.64 Mb, and the scaffold N50 length was 28.14 Mb. 24 chromosomes, assembled from the XY genome, exhibited complete concordance with the XX genome in a synteny analysis.
