Illumina RNA sequencing of the muscle tissue from individual fished at Timraroe, an island in the archipelago of Stockholm
mRNA was extracted from the tissue using polyA selection. The library was generated and sequenced at the Science for Life Laboratory (SciLifeLab) in Stockholm according to the manufacturer's instructions. The paired-end library with an insert size of 200 bp was sequenced using an Illumina HiSeq-2000 (Illumina Inc., San Diego, U.S.A) using 101 cycles per run.
