Abstract
Skipjack tuna (Katsuwonus pelamis), a highly migratory pelagic species widely distributed in tropical and subtropical oceanic regions, has consistently ranked third in global fishery landings from 2015 to 2022 and holds substantial economic significance for the coastal fisheries of Pacific Rim countries. Integrating PacBio and Hi-C data, a chromosome-level assembly of its genome was accomplished. This assembly comprises 24 pseudo-chromosomes, yielding a genome size of 827.9 Mb with a scaffold N50 length of 32.7 Mb, indicative of a highly contiguous assembly. A BUSCO assessment ascertained the comprehensiveness of the genome at 98.7%, indicative of comprehensive genomic representation. A total of 32,001 protein-coding genes were predicted with 31,993 genes (99.98%) annotated. The chromosome-level genome assembly of K. pelamis is key to understanding its evolution and genetics, facilitating targeted conservation and sustainable fishing practices for this economically important species.
期刊介绍：
Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data.
The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
