The draft genome of Labeo catla.

ABSTRACT: OBJECTIVE:Labeo catla (catla), one of the three Indian major carps, is native to the Indo-Gangetic riverine system of India as well as the rivers of Pakistan, Bangladesh, Nepal and Myanmar. Its higher growth rate and compatibility with other major carps, specific surface feeding habit, and consumer preference have increased its popularity in carp polyculture systems among the fish farmers in Indian subcontinent. Recent advancement in sequencing technology coupled with massive parallel sequencing platforms has facilitated accelerated genetic improvement in aquaculture species through integration of genomics tools. A draft genome and allied resources are lacking in catla. Therefore, in the present study, we have performed de-novo assembly of Labeo catla for the first time. DATA DESCRIPTION:A male farm reared catla was used for extracting high molecular weight genomic DNA followed by sequencing in Oxford Nanopore and Illumina platforms. Approximately, 80× coverage of sequence data was assembled adopting the hybrid assembly strategy. The assembled genome size of catla was 1.01 Gb containing 5345 scaffolds with N50 value 0.7 Mb and more than 92% BUSCO completeness. Gene annotation resulted in 25,812 predicted genes.
