Various types of hake are caught in waters around the world, specifically in the Atlantic and North Pacific. It’s available both fresh and frozen, and is sold either as a whole fish, or gutted with the head intact, or as fillets and steaks. It can occasionally also be found dried or smoked. Some varieties of hake have been greatly affected by overfishing. A lot of hake is now imported from South Africa. If sourcing sustainable fish is a concern, look for the distinctive blue MSC logo.
