Merluza is the Spanish name for hake, which is a type of fish. It is a popular menu item in Spain, and is considered a delicacy in the northeastern United States.
Merluza is a flaky white fish with a similar texture and flavor to cod, though with slightly fluffier flesh. This fish suits a variety of dishes and is popular when poached, broiled, smoked or cured. It tends to stay moist when cooked, and it is tender and tasty.
Merluza live in deep ocean waters, but they must come up to slightly shallower waters to feed at night. The bulk of fishing for merluza is done at night.
