Clarias dussumieri, commonly known as the giant river catfish, is a vital freshwater specieswith ecological and economic significance, holds significance in the catfish aquacultureglobally. Other species of clariid catfish viz., Clarias magur endemic to Indian subcontinents,and male individual of magur does not responds to the synthetic hormone for inducedbreeding, thus the male needs to be sacrifice whereas the Clarias dussumieri properlyrespond to the synthetic hormones, thus it’s become important for, comprehensive genomicinformation for this species is lacking. In this study, we present the de novo genomeassembly to address this gap by generating high quality chromosome level genome assemblyusing PacBio long reads and Hi-C scaffolding. The assembled chromosome-level genome,918.7MB in size. The genome characterization includes repeat characterization, identifying1174725 SSRs, and prediction of 25369 genes with functional annotations. The Sigle copyorthologs analysis places C. dussumieri in a distinct position with the magur. Additionally,the study delves into reproductive gene and GAD gene isoforms responsible for synthesis ofGABA, a key player in final maturation and spermiation in cat fishes. The comprehensivegenomic information offers resources for comparative genomics with Clarias magur foreconomic traits improvement.
