Fresh Fish Guide
Comparatively; fresh meat is quite forgiving compared to fresh seafood. People ask us why their fresh fish arrives with only one, two or three days ‘use by’ dates on them. The simple and short answer to that is - Fish isn’t fresh after 3 days.
The colder you can keep it, the better it will be. Every hour a piece of fish sits at room temperature is equal to aging 1 day in the fridge.
