Abstract
Sinotaia quadrata (Gastropoda: Viviparidae) is a widely distributed freshwater snail species in China. It holds significant economic value due to its dual use as both a food source and a medicinal resource. Despite its importance, genomic data for this species were lacking. Here, we present the first chromosome-scale genome assembly of S. quadrata. The final genome assembly totals 0.98 Gb (contig N50 = 98.56 Mb; scaffold N50 = 138.03 Mb), with 99.96% of sequences anchored to eight pseudochromosomes. Genome annotation predicted 16,042 protein-coding genes, with 92.67% of the complete BUSCO genes identified. This high-quality genome will provide a valuable resource for evolutionary studies within Viviparidae and enable biotechnological applications for species improvement.
