We annotated 31,656 genes and discovered that approximately 2.19% of the genome contained DNA transposon elements repressed within duplicated genes. The final assembly is 828.68 Mb with 24 chromosomes, nearly all containing telomeric repeats at their ends. Here, we generated the first chromosome-level genome assembly of chub mackerel (fScoJap1) using the Vertebrate Genomes Project assembly pipeline with PacBio HiFi genomic sequencing and Arima Hi-C chromosome contact data. They are globally consumed for their high Omega-3 content, but their population is declining due to global warming.
Chub mackerels ( Scomber japonicus) are a migratory marine fish widely distributed in the Indo-Pacific Ocean.
