| Summary: | Abstract The stone loach Barbatula barbatula is a benthic fish species widely distributed throughout Europe, primarily inhabiting stony upper sections of stream networks. This study presents an updated genome assembly of B. barbatula, contributing to the species’ available genomic resources for downstream applications such as conservation genetics. The draft assembly was 550 Mbp in size, with an N50 of 11.21 Mbp. We used the species’ available chromosome scaffolds to finish the genome. The final assembly had a BUSCO score of 96.7%. We identified 23270 protein-coding genes, and the proteome exhibited high completeness with BUSCO (93.1%) and OMArk (90.81%). Despite using multiple approaches to reduce duplicate contigs, we observed a relatively high duplicate ratio of 6.1% (BUSCO) and 8.52% (OMArk) in the annotations. We aimed to find microsatellite loci present in both the species’ publicly available genome and the new assembly to aid marker development for downstream analyses. This dataset serves as a reference for genomic analysis and is useful for developing markers to study the species’ biodiversity and support conservation efforts. |
