Molva molva, also called common ling, is a large species of the cod family. It is a salt water fish that lives in the Atlantic Ocean around Iceland, the Faroe Islands, the British Isles, along the entire western European coast, including into the Kattegat, and occasionally along the coast of Newfoundland, in addition to the western Mediterranean. As the name suggests, it is a long, slender fish that can grow up to two meters long. The adult specimens typically live in fairly deep water, from 100 meters and deeper, while the younger specimens live in shallower areas.

The ling can be used in the same way as cod, both in fresh, salted and dried form (including as lye fish). The salted roe from the ling is considered to be a delicacy in Spain, where it is known as huevas de maruca.
