Chromosome-level assembly and gene annotation of Chanodichthys dabryi genome using HiFi and Hi-C technologies (PRJCA039443)

In this study, we present a high-quality, chromosome-level genome assembly for Chanodichthys dabryi, a carnivorous cyprinid found in the lower Jinsha River and upper Yangtze River, as well as major tributaries in China. Utilizing PacBio HiFi and Hi-C sequencing technologies, we generated an assembly of approximately 1106.1 Mb, with 96.6% of the sequence anchored to 24 chromosomes and a contig N50 of 43 Mb. Assembly quality was supported by BUSCO (98.7% complete) and Merqury (over 98% accuracy).

本研究报道了达氏鲌（Chanodichthys dabryi）的高质量染色体水平基因组组装结果。该物种为肉食性鲤科鱼类，栖息分布于中国金沙江下游、长江上游及其主要支流。本研究采用PacBio HiFi测序与Hi-C测序技术，构建得到总长度约1106.1 Mb的基因组组装序列，其中96.6%的序列被锚定至24条染色体，重叠群N50（contig N50）为43 Mb。该组装的质量经BUSCO分析（完整度达98.7%）与Merqury评估（准确率超98%）得到验证。
