Abstract The American bullfrog (Aquarana catesbeiana) is both an economically important aquaculture species and a globally distributed invasive organism with high environmental adaptability. In this study, we present a high-quality chromosome-level genome assembly for the species, comprising 13 chromosomes with a total length of 6.32 Gb and a scaffold N50 of 691.8 Mb. Genome completeness was evaluated at 95.5% using BUSCO and 99.9% using Merqury. Repetitive sequences accounted for 79.51% of the genome. Through a combination of RNA-seq, Ab initio and homology-based gene prediction, we identified 32,382 protein-coding genes, with 98.96% of these genes functionally annotated. This chromosome-level assembly provides an important resource for future studies on the evolution, functional genomics and molecular breeding of the American bullfrog.
