The genome sequence of the thickback sole, Microchirus variegatus (Donovan, 1808).

We present a genome assembly from an individual female Microchirus variegatus (the thickback sole; Chordata; Actinopteri; Pleuronectiformes; Soleidae). The genome sequence is 724.7 megabases in span. Most of the assembly is scaffolded into 23 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 17.42 kilobases in length.
