Because of this distinction, you may safely use fish even after the sell by date has lapsed. If there is a use-buy date on fresh fish, then it is recommended to either cook or freeze the fish by that date. Commercially frozen fish, if kept frozen, can be safely stored for 10-12 months.
when starts the shelf life ? from the day they catch the fish or when i buy the fish by my retailer?, and how can my retailer know how long the (fresh) fish is already on the way until they get it to sell it, can they check if the fish is stored, before even my retailer or grocery store will get the (fresh) fish.
