Fish odors are usually the result of a breakdown of proteins. The odorant is trimethlamine. The warmer the temperature of the stored fish the faster it is produced. The reason is that a lot of fish markets (the stupid ones) store the fish directly on an ice bed. The problem is that cold goes down (and heat goes up) therefore the exposed/top side of the fish can be at almost room temperature and unless the help are flipping the fish over every hour or so, bad, smelly things will happen. Most “fresh” fish are anything but fresh. Want fresh fish? Buy frozen fish because in most cases, it is caught, processed and flash frozen within an hour right on a giant factory ship. Unlike when it was frozen years ago the methodology used today freezes it so quickly it retains its integrity when thawed properly. Or only buy it from a fish market that has a dock behind it where the fishing boats bring it directly, or a fish market that uses proper cold-hold cases. Those are the ones they keep meat an chicken in.
