Abstract Marine medaka ( Oryzias melastigma ) is considered to be a useful fish model for marine and estuarine ecotoxicology studies and has good potential for field‐based population genomics because of its geographical distribution in Asian estuarine and coastal areas. In this study, we present the first whole‐genome draft of O. melastigma . The genome assembly consists of 8,602 scaffolds (N50 = 23.737 Mb) and a total genome length of 779.4 Mb. A total of 23,528 genes were predicted, and 12,670 gene families shared with three teleost species (Japanese medaka, mangrove killifish and zebrafish) were identified. Genome analyses revealed that the O. melastigma genome is highly heterozygous and contains a large number of repeat sequences. This assembly represents a useful genomic resource for fish scientists.
