Subject area	Genetics and Transcriptomics
More specific subject area	Transcriptomics of Atlantic chub mackerel Liver
Type of data	Raw reads of DNA sequences
How data was acquired	A liver sample of Atlantic chub mackerel, Scomber colias, was collected for total RNA isolation. It was prepared paired-end library and sequenced by the Hiseq. 4000 system. The obtained data were subjected to de novo assembly and annotated using Trinotate.
Data format	Raw data in FASTQ, transcriptome assembly and Final transcriptome assembly in FASTA format.
Experimental factors	One specimen of S. colias was obtained from North Atlantic waters.
Experimental features	The de novo assembling of the transcriptome, decontamination, filtration and the functional annotation of Atlantic chub mackerel liver was performed.
Data source location	Portugal (41.501944 N 8.851667 W)
Data accessibility	The raw FASTQ files were deposited in the NCBI SRA database with accession number SRX3462868 (https://www.ncbi.nlm.nih.gov/sra/SRX3462868).
	The decontaminated transcriptome assembly was deposited in the NCBI TSA database with accession number GGCI00000000.1 (https://www.ncbi.nlm.nih.gov/nuccore/GGCI00000000.1).
	The final transcriptome assembly was deposited in the figshare digital repository (https://figshare.com/s/a97f1d5b37d174d1d819).
