I had a summer job working in a fish factory shelling scallops.
It involved sitting in what was effectively a huge fridge surrounded by other people doing the same thing. The sound of the knives on the shells was so loud that you couldn't really talk to the person sitting next to you. We had gloves, but the combination of the knives and the shells meant the gloves would have holes in them after a couple of hours so your hands would be wet all day. The smell got into your hair and clothes. And you'd start at 04:30 or 05:30 depending on when the boats came in.
i remember that smell. i worked the "slime line" in a fish processing plant in Seldovia AK for a summer. basically scooping fish stuff out with a metal spoon connected to a hose for 12-14 hours. fish scales everywhere.
