Annotation of <i>Eleutheronema rhadinum</i>

The East Asian fourfinger threadfin (<i>Eleutheronema rhadinum</i>, Jordan &amp; Evermann, 1902), an endemic species in East Asia, is distributed across coastal waters of China (including Taiwan Province), Japan, and northern Vietnam. Owing to its high market value, <i>E. rhadinum</i> is considered an economically important species in China and is widely targeted by gillnet, set net, and rod-and-reel fisheries in both coastal and inshore waters for commercial and recreational purposes. Despite its ecological and economic significance, the orthologous relationships and phylogenetic history of <i>E. rhadinum</i> remain largely uncharacterized.In this study, we performed whole-genome sequencing using PacBio SMRT and Hi-C technologies to generate a high-quality, chromosome-level genome assembly. The assembled genome size was 585.27 Mb, with a contig N50 of 24.22 Mb and 99.73% of sequences anchored to 26 chromosomes. A total of 23,090 protein-coding genes were predicted, and approximately 18.53% of the genome was identified as repetitive sequences.
