Abstract

We present a genome assembly from an individual male Gasterosteus aculeatus (three-spined stickleback; Chordata; Actinopteri; Perciformes; Gasterosteidae). The assembly contains two haplotypes with total lengths of 511.14 megabases and 457.35 megabases. Most of haplotype 1 (97.82%) is scaffolded into 22 chromosomal pseudomolecules, including the X and Y sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 16.56 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.
