Nothobranchius rachovii is a species of freshwater annual killifish native to Africa. This organism is an attractive model in aging studies because of short lifetime and rapid maturation. In this study, we present draft genome assembly of this organism based on Nanopore reads and polished with Illumina reads. We tested four popular Nanopore reads assemblers (Flye, MaSuRCA, Shasta, wtdbg2) and two polishers (Pilon and MaSuRCA-polish tool). We selected the best combination of these tools in terms of contig length and assembly completeness.
