Fatty acid profile of cooked leg meat and raw hepatopancreas of red king crab (Paralithodes camtschaticus) during three-month live holding without feeding at 5 and 10 °C

•Live holding without feeding does not alter the omega−3 proportion in leg meat.•Fatty acid profile of hepatopancreas is affected by live holding without feeding.•During starvation, 14:0, 16:0, 16:1n−7c, 18:1n−9t, and 22:5n−3c are utilized first.•Higher live holding temperature leads to earlier alteration of fatty acid profile.•Baseline information for selecting and developing suitable feed for red king crab.
